To assess the radiology department chairs' opinions concerning current status and plans for teaching ultrasound to medical students, the American College Taskforce on Radiology Ultrasound Education, commissioned by the American College of Radiology, distributed a survey to 142 radiology chairs and a medical school dean subgroup.The response rate was 30% (42/142), and 76% indicated ultrasound was currently part of the medical student curriculum. In preclinical years, radiology involvement was only 6.4%. During clinical years, radiology led ultrasound education with 51.7% in general and 82.9% in elective rotations. Regarding actual content, top 4 results were evenly distributed between learning hands-on scanning (81.1%), diagnostic use of ultrasound (75.7%), anatomy/pathology (75.7%), and ultrasound guidance for procedures (54.0%). Educational leaders in preclinical courses were emergency medicine (72.7%) followed by radiology (45.4%) physicians. During clinical years, leaders were radiology (52.6%) and emergency medicine (47.4%) physicians. Most chairs stated that knowledge of diagnostic ultrasound should be mandatory (76.2%), stressing the importance of teaching the diagnostic capabilities and uses of ultrasound as the primary goal (78.8%). Perceived barriers to implementation were evenly distributed between lack of space in the curriculum (55.6%), lack of faculty (48.2%), lack of resources (44.4%), and lack of institutional support (40.7%). The American College Taskforce on Radiology Ultrasound Education survey shows that radiology's role in ultrasound undergraduate education occurs almost exclusively during clinical years, and the chairs voice a desire to improve upon this role. Barriers include both intradepartmental (faculty and resources) and institutional (curricular) factors.

Objectives The growing body of evidence suggesting that lifestyle changes and aggressive medical management reduce the risk of strokes in patients with carotid stenosis has fostered interest in noninvasive screening. The objective of this study was to develop recommendations for follow-up carotid ultrasound surveillance of patients with Methods This retrospective observational cohort study includes 2956 patients seen between August 1998 and March 2015 in 4440 visits. Data analysis was restricted to 7710 carotid ultrasounds. Primary outcome was progression of carotid stenosis as defined by the “bulb” method: baseline stenosis of 0%–39% progressed to 40%–59% on subsequent examination, baseline stenosis of 0%–39% progressed to ≥60%, or baseline of 40%–59% progressed to ≥60%. Progression was estimated using Cox proportional hazard ratios and the Kaplan-Meier method. Results More than 10% of patients progressed in the 40%–59% baseline group within 12 months compared to 78 months for the 0%–39% baseline group. Patients who progressed had a higher proportion of peripheral vascular disease, and current/former smoking compared to those who did not. While there were statistically significant correlations between medication classes and comorbidities, none of the medications studied appeared to slow carotid stenosis progression. Conclusions In our experience, for patients with a 0%–39% carotid stenosis, follow-up examination should be performed at 6-year intervals. For patients with 40%–59% carotid stenosis, follow-up should be obtained annually to identify those who progress to a level requiring intervention. Future studies should examine whether study findings can be replicated using other approaches for determining carotid stenosis.

More than 25% of the present radiology workforce, or nearly 8300 radiologists, are actively practicing late-career radiologists. While these individuals could decide to retire from active practice, their continued presence in the workforce helps to maintain adequate and appropriate patient imaging services. To ensure their continued participation, issues important to all late-career radiologists need to be appreciated, discussed, and addressed. These issues include call-duty requirements, compensation, physical and cognitive health, and organized phase-out programs. The gamut of these issues is addressed in this review article. ©RSNA, 2018.

Hepatorenal index (HRI) has been shown to be an effective, noninvasive ultrasound tool to screen patients for those with or without >5% hepatic steatosis. Objective: The aim of this study was to further refine this HRI tool in order to stratify patients according to their degree of liver steatosis and give direction as to which patients should undergo random liver biopsy. Methods: We conducted a retrospective review of 267 consecutive patients from 2015 to 2017 who had abdominal ultrasounds and a subsequent random liver biopsy within one month. The HRI was calculated and compared with the percent steatosis as assessed by histology. Results: An HRI of ≤1.17 corresponds with >95% positive predictive value of ≤5% steatosis. Between HRI values 1.18 and 1.39, performance of steatosis prediction is mixed. However, for values 1.37. An HRI of ≥1.4 corresponds with >95% positive predictive value of ≥10% steatosis. Conclusion: HRI is an accurate noninvasive tool to quantify degree of steatosis and guide who should undergo random liver biopsy, potentially significantly reducing the total number of necessary liver biopsies.

Increasingly, radiologists' workplaces revolve around PACS and digital imaging. Use of these technologies can lead to repetitive strain injuries, many of which can be exacerbated by specific features of a radiology practice environment. Ergonomic approaches, such as proper reading room structure, lighting, temperature, noise, and equipment setup, can help decrease the frequency and severity of repetitive strain injuries and improve radiologist productivity. However, ergonomic approaches are complex, include all aspects of the radiology practice environment, and are best implemented along with proper training of the practicing radiologists. The ergonomic approaches considered most important by members of the ACR Commission on Human Resources are presented in this report, and this information may serve as an aid in departmental planning.

Objectives-The purpose of this study was to determine the incidences and rates of progression of varying degrees of carotid stenosis that do not require intervention according to the Asymptomatic Carotid Atherosclerosis Study, the European Carotid Surgery Trial, and the North American Symptomatic Carotid Endarterectomy Trial, and from this information, to provide evidence-based recommendations for follow-up imaging.

Workplace bullying is common in health care and has recently been reported in both radiology and radiation oncology. The purpose of this article is to increase awareness of bullying and its potential consequences in radiology and radiation oncology. Bullying behavior may involve abuse, humiliation, intimidation, or insults; is usually repetitive; and causes distress in victims. Workplace bullying is more common in health care than in other industries. Surveys of radiation therapists in the United States, student radiographers in England, and physicians-in-training showed that substantial proportions of respondents had been subjected to workplace bullying. No studies were found that addressed workplace bullying specifically in diagnostic radiology or radiation oncology residents. Potential consequences of workplace bullying in health care include anxiety, depression, and health problems in victims; harm to patients as a result of victims' reduced ability to concentrate; and reduced morale and high turnover in the workplace. The Joint Commission has established leadership standards addressing inappropriate behavior, including bullying, in the workplace. The ACR Commission on Human Resources recommends that organizations take steps to prevent bullying. Those steps include education, including education to ensure that the line between the Socratic method and bullying is not crossed, and the establishment of policies to facilitate reporting of bullying and support victims of bullying.

The transition of leadership within radiology practices is often not a planned replacement process with formal development of potential future leaders. To ensure their ongoing success, however, practices need to develop comprehensive succession plans that include a robust developmental program for potential leaders consisting of mentoring, coaching, structured socialization, 360-degree feedback, developmental stretch assignments, job rotation, and formal education. Succession planning and leadership development will be necessary in the future for a practice to be successful in its business relationships and to be financially viable.

Objectives We sought to assess midterm sonographic findings in patients after stenting for hepatic artery stenosis. Methods Thirty-nine hepatic artery stent procedures were performed for hepatic artery stenosis after liver transplantation between September 2009 and December 2013. Thirty cases were technically successful and met the minimum follow-up time (76 days, defined by earliest diagnosed stenosis). Routine ultrasound surveillance was obtained on all patients, and statistical analysis of the findings in the patency and restenosis groups was performed. Results Of the 30 cases, restenosis occurred 9 times in 6 patients. Mean follow-up was 677 days. Mean time to restenosis was 267 days. Five cases (56%) were identified within the first 6 months after stent placement. Four cases (44%) were recognized in the second year after stent placement. Prior to the sonographic diagnosis of restenosis, the mean resistive indices of the main (.64 versus .57, P

Clinical depression affects physicians, including radiologists. Medical professionals, including radiologists, may be more comfortable treating a patient than being one, and psychiatric issues may be regarded as taboo for discussion, so the issue of clinical depression in the specialty and subspecialty has not received widespread attention. Specifically, a review of the national and international literature in PubMed, Scopus, and Google reveals few publications dedicated to the issue of clinical depression in radiology; although statistically, they must exist. The purpose of this report is to define the terms and describe the manifestations and scope of the issues related to clinical depression, with special attention given to risk factors unique to radiologists, such as working in low ambient light or near different fields of magnetic strength. By the end of the article, it is the authors' hope that the reading radiologist will be aware of, and open to, the possibility of clinical depression in a colleague or within his or herself because clinical depression is common and it is important to get help.

Radiologists may choose or need to leave radiology as a career. The purpose of this article is to discuss options available to radiologists beyond their clinical careers.

Burnout is a concern for radiologists. The burnout rate is greater among diagnostic radiologists than the mean for all physicians, while radiation oncologists have a slightly lower burnout rate. Burnout can result in unprofessional behavior, thoughts of suicide, premature retirement, and errors in patient care. Strategies to reduce burnout include addressing the sources of job dissatisfaction, instilling lifestyle balance, finding reasons to work other than money, improving money management, developing a support group, and seeking help when needed.

The objective of our study was to assess utilization of the Family and Medical Leave Act (FMLA) in radiology practices in 2016 and compare with 2015 utilization.The Practice of Radiology Environment Database was used to identify practice leaders, and these leaders were asked to complete the annual American College of Radiology Commission on Human Resources workforce survey. The 2017 survey, which asked about 2016 experiences, again included questions about the number of radiologists in each practice who took FMLA, reasons why, and how absences were covered.Twenty-six percent (477/1811) of practice leaders responded to the survey. Of these respondents, 73% (346/477) answered FMLA questions, and 23% (80/346) of those answered affirmatively that a radiologist in their practice had taken FMLA leave in 2016 (previously 15% in 2015; p = 0.15). The reasons for FMLA leave included taking care of a newborn or adopted child (57%, previously 49%; p = 0.26), personal serious health condition (35%, previously 42%; p = 0.31), caring for an immediate family member (8%, unchanged), and engaging in active military duty (1%, unchanged). Although more women (72%) than men (32%) took FMLA leave for the first reason (p0.01), more men (63%) than women (18%) took FMLA leave for the second (p0.01), and there was no significant difference between women (10%) and men (5%) taking leave to care for an immediate family member (p = 0.18). Most practices (80%) again made no workforce changes to cover absences due to FMLA leave (previously 82%).Utilization of FMLA leave in radiology practices in 2016 was similar to that in 2015 and represents the beginning of longitudinal accrual of data on this important topic for both male and female radiologists.

Background The ACR Commission on Human Resources and Commission on General, Small and Rural Practice collaborated on developing a question regarding hiring preferences to include in the annual Commission on Human Resources Workforce Survey in order to understand hiring preferences. Methods Group leads were asked to rank five types of prospective radiologists from most desirable to least desirable for hire on the basis of the needs of their practices: single-specialty radiologists, focusing on only one subspecialty; single-specialty radiologists with general capabilities; multispecialty radiologists; general radiologists; and radiologists who did two fellowships in the same specialty. Results The most desired hiring preference was for a single-specialty radiologist with general capabilities. Sixty-eight percent of the practice leaders identified a single-specialty radiologist with general capabilities as the most desirable type of individual to hire, compared with 21% who chose multispecialty radiologists, 13% who chose single-specialty radiologists and general radiologists, and 5% who expressed a preference for radiologists who did two fellowships in the same specialty. Conclusions The most desirable candidates for hire appear to be those who are fellowship trained as subspecialists but who are also capable of reading in other clinical areas or modalities. This preference is true for most private practices, multispecialty practices, and hospital-owned practices. In contrast to those practices, chairs and leaders of academic medical center practices prefer to hire single-specialty radiologists slightly more than single-specialty radiologists with general capabilities.

Midcareer job transitions are occurring for many reasons other than individual radiologists' professional performance quality, affability, and desire for geographic change. New causes seem to be related to the present health care environment. All radiologists should be aware of this disruptive change to the profession and of the resources available to help job seekers find new positions.

Radiologists are faced with ever-increasing challenges in the needs of the practice, in both private and academic settings. Targeted information about protecting and maintaining the physical, mental, and emotional health of the radiologist is highly limited. Impairment is a functional classification that implies that the individual affected by a disease is unable to perform specific activities. Radiologists can suffer from the same illnesses as any human being, which include substance abuse and addiction, as well as chronic infectious diseases such as human immunodeficiency virus, hepatitis B and C, and tuberculosis. This article is intended to educate radiologists and leaders about various forms of physician impairment. It provides discussion of the challenges related to such impairment and provides tools and resources to address the impaired radiologist.

Practice leaders surveyed in the 2017 ACR Human Resources Commission workforce survey reported that 25% of the radiologists or radiation oncologists they supervised had neck pain, 32% had low back pain, and 16% were dealing with a repetitive stress injury. The prevalence rates of these musculoskeletal ailments among radiologists and radiation oncologists were consistent with those reported in the literature in other populations. However, these prevalence rates may be underestimated because practice leaders, not the radiologists themselves, were surveyed, and the leaders may not be aware of all injuries.

Radiologists today are faced with the challenges of maintaining and balancing individual and family health needs and the demands of the workplace. To provide the highest quality and safest care of our patients, a corresponding ethos of support for a healthy workforce is required. There is a paucity of targeted information describing protections for and maintenance of the health of the practicing radiologist, in both private and academic settings. However, a review of existing family and medical leave policies may be helpful to practice leaders and practicing radiologists as a platform for the development of strategic workforce plans. This writing, by members of the ACR Commission on Human Resources, addresses the following areas: (1) medical leave, (2) maternity and/or paternity leave, and (3) disability.

Merely suggesting that radiologists answer the call to bolster and secure the future of their own specialty has not resulted in increased activism. Therefore, the ACR Commission on Human Resources has developed a definition for the concept of citizenship in radiology and explicit descriptions of the activities associated with it. Furthermore, the authors introduce a methodology for the measurement and valuation of individual radiologists' contributions to group practices and to the specialty as a whole. These measures can in turn be used to promote, acknowledge, recognize, and incentivize citizenship activity among radiologists at the local, regional, and national levels.

BackgroundHepatic artery stenosis (HAS) after orthotopic liver transplantation is a significant risk factor for subsequent hepatic artery thrombosis (HAT). HAT is associated with a 30%-50% risk of liver failure culminating in retransplantation or death. Traditional treatment of hepatic artery complications has been surgical, with hepatic artery revision or retransplantation. Endovascular therapy of HAS, described primarily in the interventional radiology literature, may provide a less-invasive treatment option.MethodsThis was a retrospective review of all endovascular interventions performed for HAS after orthotopic liver transplantation over a 31-month period (August 2009 to January 2012). Patients with duplex ultrasound imaging evidence of severe main HAS (peak systolic velocity of >400 cm/s, resistive index of

Retirement and issues associated with the initiation of retirement have undergone extensive change in the past decade. Multiple factors, including economic conditions, have resulted in a delay in the initiation of retirement. Delayed retirement of senior radiologists is a factor contributing to a diminished job market for entering radiology graduates. These senior radiologists have extensive experience in operational issues and understanding complex relationships with other health professionals, hospitals, and often medical schools. In addition, although they may not be as facile with MRI or PET/CT, senior radiologists have a tremendous command of traditional imaging, which is lacking in recently trained radiologists. The authors examine many of the issues related to delayed retirement and propose some possible solutions.

OBJECTIVE. The risk of injury associated with long-term occupational exposure to ionizing radiation is low for radiologists. The purpose of this article is to systematically review and inform radiologists about radiation-related effects to which they are potentially susceptible. CONCLUSION. Formal education and training on radiation safety and management, careful attention to good radiation protection habits, and continued emphasis on radiation management and the as low as reasonably achievable principle are recommended for all radiologists.

Purpose Despite federal and state laws mandating lactation facilities for eligible employers, no reliable data exist regarding the availability of lactation facilities in the radiology workforce. To fill this void, the ACR Commission on Human Resources added new questions to its annual electronic survey to better understand this aspect of the workforce situation for radiologists. Methods As done annually, the Practice of Radiology Environment Database was utilized to identify leaders of radiology practices, who were asked to complete an electronic survey developed by the ACR Commission on Human Resources. Among other questions, leaders were asked, "Does your radiology or radiation oncology practice have a dedicated lactation facility?" Results Overall, 579 of 1,815 (32%) practice group leaders responded to the survey. Of 579, 394 responded to lactation question. Of 394, 51 (13%) reported affirmatively that they do have dedicated lactation facilities, and 343 of 394 (87%) responded that they do not have dedicated lactation facilities. Conclusion The vast majority of radiology and radiation oncology practices in the United States do not have dedicated lactation facilities; given the numerous benefits to breastfeeding mothers and babies, this impacts not only women but also men given that they too would like to have healthy colleagues with minimal absenteeism.

The number of 4th-year medical student applications to the field of diagnostic radiology has decreased from 2009 to 2015. The purpose of this study was to learn how radiology departments are recruiting medical students.An anonymous online survey hyperlink was distributed to the members of the Society of Chairs of Academic Radiology Departments regarding both innovative and proven recruitment strategies. The results were synthesized with a recently published survey of medical students about factors influencing them to go into radiology.Forty of 126 radiology departments completed the survey. Most felt that radiology exposure and curricula require alteration given recent downward trends in medical student applications. A majority (79%) had changed their outreach to medical students in response to these trends. The responding department chairs felt that interactive learning while on rotation was the most important strategy for recruitment. The presence of a diversity program, dedicated medical school educator, or rotating daily assignment for students did not affect the likelihood of filling residency spots in the main match.Many radiology departments are changing their outreach to medical students to improve recruitment. Effective strategies to focus on include early active outreach by involving students in the radiology department, thereby framing radiologists as clinicians.

Purpose To assess gender utilization of the Family and Medical Leave Act (FMLA) in radiology practices across the United States. Methods The Practice of Radiology Environment Database was utilized to identify U.S. practice leaders, who were asked to complete an electronic survey developed by the ACR Human Resources (HR) Commission. In 2016, new survey questions asked about number of radiologists in each practice who took FMLA, the reasons why, the average number of weeks taken, and how such absences were covered. Results Thirty-two percent (579/1815) of practice group leaders responded to the survey and of these, 73% (432/579) answered FMLA questions, with 15% of those (64/432) answering affirmatively that a radiologist in their practice had taken FMLA leave. Reasons for this in 2015 included to care for a newborn/adopted child (49%), because of a personal serious health condition (42%), to care for an immediate family member (8%), or for active military duty (1%). Women took a greater number of weeks of FMLA leave than men for all reasons (care of newborn/adopted child: 10.7 versus 4.7; personal serious health condition: 10.3 versus 8.0; care of immediate family member: 9.7 versus 8.7) except for military duty (24 weeks taken, all by men). At least 69% of leave time was paid, irrespective of reason for leave or gender of person taking it. Most practices (82%) made no workforce changes to cover FMLA leave. Conclusions Both genders of radiologists needed absences from work for FMLA-sanctioned reasons.

Purpose The ACR Commission on Human Resources continues to conduct its annual electronic survey to better understand the present workforce scenario for radiologists. Methods The Practice of Radiology Environment Database was used to identify group leads, who were asked to complete an electronic survey developed by the Commission on Human Resources. The survey asked group leaders to report the number of radiologists they currently employ or supervise, the number hired in 2014, and the numbers they plan to hire in 2015 and 2018. The leaders were asked to report the subspecialty area used as the main reason for hiring each physician, as well as the ages and genders of their current workforce. Results Thirty-two percent of group leaders responded to the survey, corresponding to 12,079 radiologists or 39% of all practicing radiologists. Twenty-one percent of the workforce is female and 79% is male. Ten percent of radiologists older than 65 years are women, while 32% younger than 35 are women. Twelve percent of radiologists work part-time, corresponding to a breakdown of 10% of men and 24% of women working part-time. The current workforce is 13% general radiologists and 87% subspecialists. In 2015, a projected 1,131 to 1,484 jobs will be available for radiologists. Conclusions Job opportunities for radiologists seem to be increasing compared with 2013 and are relatively similar to 2014. Radiologists continue to subspecialize in greater numbers, but only 39% of radiologists practice more than 50% of the time in their subspecialties.

Objectives— The purposes of this study were to develop a protocol for evaluating pancreas allografts, to describe a method for successfully studying pancreatic transplants, and to determine whether the resistive index (RI) of the splenic artery is a useful differentiator between complications.Methods— We retrospectively analyzed clinical, surgical, procedural, and radiologic reports in 51 consecutive patients undergoing 182 sonographic examinations during a 4.5-year period. Complications included splenic vein thrombosis, rejection, and pancreatitis. We obtained RIs in normal and complication groups and performed mixed model regression methods and receiver operating characteristic analysis.Results— The mean RI ± SD for normal transplants was 0.65 ± 0.09; for splenic vein thrombosis, 0.76 ± 0.09; after resolution of splenic vein thrombosis, 0.73 ± 0.09; during rejection, 0.94 ± 0.09; after successful treatment of rejection, 0.74 ± 0.09; for pancreatitis, 0.83 ± 0.09; and for fluid collections, 0.66 ± 0.09. There was a statistically significant difference (P < .05) between normal transplants and splenic vein thrombosis (P = .0003), rejection (P < .0001), and pancreatitis (P = .04). A significant difference was also seen between rejection and successful treatment thereof (P < .0001).Conclusions— We developed a protocol that allowed us to successfully evaluate 96% of the pancreatic allografts studied. Furthermore, our data show that the RI can be used as a therapeutic guide. When the RI is less than 0.65, the risk of vascular abnormalities is very low; however, fluid collections may be present. When greater than 0.75, splenic vein thrombosis, pancreatitis, or rejection should be suspected. When greater than 0.9, rejection must be seriously considered.

Stroke accounts for a significant degree of morbidity, mortality, and health care expenditure in this nation despite the many medical and surgical preventive measures we have in place. This article discusses how developing a universally accepted effective screening examination will help decrease this health care burden. Risk factors for the development of cardiovascular disease are explored. Special attention is given to the pathogenesis and diagnosis of carotid atherosclerosis because it accounts for a large percentage of both embolic and ischemic strokes. Current diagnostic testing, in particular duplex carotid sonography, and proposed screening strategies for the detection of carotid atherosclerosis and other risk factors are reviewed. Sex-related differences proposed in the current literature are also explored in this article because they may affect how we screen for and prevent stroke.Developing an accurate, cost-effective, and universally acknowledged screening test will allow us to maximize the preventive medical and surgical measures we already have in place. Doing so will in turn lead to a significant decrease in the morbidity, mortality, and health care expenditure associated with stroke.

The objective of this study was to prospectively evaluate the use of point shear wave elastography for the assessment of liver fibrosis and to determine the usefulness and optimal location for obtaining elastography measurements in native and transplanted livers. Point shear wave elastography measurements were obtained from 100 consecutive patients presenting for percutaneous liver biopsy. Measurements were acquired within both the superior right hepatic lobe (segments VII/VIII) via an intercostal approach and the inferior right hepatic lobe (segments V/VI) via a subcostal approach. Analysis of variance was used to assess statistical differences between the degree of fibrosis on percutaneous liver biopsy and elastography measurements. No statistical difference was present when comparing elastography measurements in patients with hepatic steatosis compared with patients without steatosis (P = 0.2759). There was no difference in the accuracy of elastography measurements in native livers versus transplanted livers (P = 0.221). Point shear wave elastography can accurately differentiate between patients with no-to-mild hepatic fibrosis (F0-F1) and moderate-to-severe hepatic fibrosis (≥F2) with sensitivity of 72% and specificity of 69%. Point shear wave elastography can be used as a noninvasive method to assess fibrosis in patients with native or transplanted livers. In addition, measurements can be combined or taken separately from either the superior or inferior right hepatic lobe. The presence of hepatic steatosis does not affect the accuracy of point shear wave elastography. However, shear wave elastography values in patients with body mass index greater than 40 should be interpreted with caution.

The aim of this study was to survey fourth-year medical students, both those choosing and those not choosing diagnostic radiology as their specialty, regarding factors influencing their choice of specialty and their perceptions of radiology.A voluntary anonymous online survey hyperlink was sent to 141 US medical schools for distribution to fourth-year students. Topics included demographics, radiology education, specialty choice and influencing factors, and opinions of radiology.A representative sampling (7%) of 2015 fourth-year medical students (n = 1,219; 51% men, 49% women) participated: 7% were applying in radiology and 93% were not. For respondents applying in radiology, the most important factor was intellectual challenge. For respondents applying in nonradiology specialties, degree of patient contact was the most important factor in the decision not to choose radiology; job market was not listed as a top-three factor. Women were less likely than men to apply in radiology (P.001), with radiology selected by 11.8% of men (56 of 476) and only 2.8% of women (13 of 459). Respondents self-identifying as Asian had a significantly higher (P = .015) likelihood of selecting radiology (19 of 156 [12.2%]) than all other races combined (44 of 723 [6.1%]). Respondents at medical schools with required dedicated medical imaging rotations were more likely to choose radiology as a specialty, but most schools still do not require the clerkship (82%).The reasons fourth-year medical students choose, or do not choose, diagnostic radiology as a specialty are multifactorial, but noncontrollable factors, such as the job market, proved less compelling than controllable factors, such as taking a radiology rotation.

Objectives-Marshall et al (AJR Am J Roentgenol 2012; 199:997-1002) initially demonstrated that the hepatorenal index is an effective and noninvasive tool to screen patients for hepatic steatosis. The aim of this study was to determine whether the hepatorenal index can be accurately calculated directly from a picture archiving and communication system (PACS) quickly and efficiently without the need for the multiple steps and specialized software used to calculate hepatorenal index in the study by Marshall et al. Methods-We evaluated 99 of the 101 patients included in the study by Marshall et al: patients being followed by hepatologists with plans for liver biopsy. The hepatorenal index was calculated by using Digital Imaging and Communications in Medicine (DICOM) images from a PACS and a markup region-of-interest tool. We compared this value to the value that Marshall et al derived by using specialized software and to standard histologic estimates. We created similar subgroups: patients with steatosis based on histologically estimated intracellular fat exceeding 5% and patients without steatosis. Results-The mean hepatorenal index ± SD for those with steatosis according to histologic findings was 1.87 ± 0.6, and for those without, it was 1.14 ± 0.2. A hepatorenal index of 1.34 or higher had 92% sensitivity for identifying fat exceeding 5%, 85% specificity, a 94% negative predictive value, and a 79% positive predictive value. Substantial agreement was found between the hepatorenal index calculated from DICOM images and macrovesicular fat categorized at the cut point of 1.34 or higher (? = 0.76; 95% confidence interval, 0.62-0.88; P < .001). Conclusions-The hepatorenal index can be quickly and accurately calculated from DICOM images directly on a PACS without supplementary software.

The results of a survey sent to practice leaders in the ACR Practice of Radiology Environment Database show that the majority of responding groups will continue to hire recently trained residents and fellows even though they have been unable to take the final ABR diagnostic radiology certifying examination. However, a significant minority of private practice groups will not hire these individuals. The majority of private practices expect the timing change for the ABR certifying examinations to affect their groups' function. In contrast, the majority of academic medical school practices expect little or no impact. Residents and fellows should not expect work time off or protected time to study for the certifying examination or for their maintenance of certification examinations in the future.

n important first step in the workup of a patient with a palpable testicular mass is sonography, considered by some to be an extension of the physical examination.1 Sonographic accuracy in the determination of intratesticular versus extratesticular masses has been reported as high as 99%.2 This distinction is important because most intratesticular masses prove to be malignant.3 Benign causes of intratesticular masses include hematoma, orchitis, torsion, infarction, and abscesses.4 The case presented had an unusual cause of an intratesticular mass.

The Society of Radiologists in Ultrasound convened a multidisciplinary panel of experts in the field of vascular ultrasonography (US) to come to a consensus regarding Doppler US for assistance in the diagnosis of carotid artery stenosis. The panel's consensus statement is believed to represent a reasonable position on the basis of analysis of available literature and panelists' experience. Key elements of the statement include the following: First, all internal carotid artery (ICA) examinations should be performed with grayscale, color Doppler, and spectral Doppler US. Second, the degree of stenosis determined at grayscale and Doppler US should be stratified into the categories of normal (no stenosis), less than 50% stenosis, 50 to 69% stenosis, > or =70% stenosis to near occlusion, near occlusion, and total occlusion. Third, ICA peak systolic velocity (PSV) and the presence of plaque on grayscale and/or color Doppler images are primarily used in the diagnosis and grading of ICA stenosis. Two additional parameters (the ICA-to-common carotid artery PSV ratio and ICA end diastolic velocity) may also be used when clinical or technical factors raise concern that ICA PSV may not be representative of the extent of disease. Fourth, ICA should be diagnosed as normal when ICA PSV is less than 125 cm/second and no plaque or intimal thickening is visible, less than 50% stenosis when ICA PSV is less than 125 cm/second and plaque or intimal thickening is visible, 50 to 69% stenosis when ICA PSV is 125 to 230 cm/second and plaque is visible, > or =70% stenosis to near occlusion when ICA PSV is more than 230 cm/second and visible plaque and lumen narrowing are seen, near occlusion when there is a markedly narrowed lumen on color Doppler US, and total occlusion when there is no detectable patent lumen on grayscale US and no flow on spectral, power, and color Doppler US. Fifth, the final report should discuss velocity measurements and grayscale and color Doppler findings. Study limitations should be noted when they exist. The conclusion should state an estimated degree of ICA stenosis as reflected in these categories. The panel also considered various technical aspects of carotid US and methods for quality assessment, and identified several important unanswered questions meriting future research.

Objective. To describe the importance of obtaining erect views when evaluating the celiac artery with sonography. Methods. Two patients had duplex and color flow Doppler sonographic evaluations of the celiac artery, including inspiration, expiration, and erect views. Results. Both patients had elevated celiac artery velocities with inspiration and expiration. These results alone would suggest celiac artery stenosis. With erect views, the celiac artery velocities returned to normal. The addition of erect views allowed the correct diagnosis of median arcuate ligament syndrome to be made. Conclusions. When evaluating the celiac artery, it is important to include erect views to prevent misdiagnosis of celiac artery stenosis.

The Society of Radiologists in Ultrasound convened a multidisciplinary panel of experts in the field of vascular ultrasonography (US) to come to a consensus regarding Doppler US for assistance in the diagnosis of carotid artery stenosis. The panel's consensus statement is believed to represent a reasonable position on the basis of analysis of available literature and panelists' experience. Key elements of the statement include the following: (a) All internal carotid artery (ICA) examinations should be performed with gray-scale, color Doppler, and spectral Doppler US. (b) The degree of stenosis determined at gray-scale and Doppler US should be stratified into the categories of normal (no stenosis),50% stenosis, 50%-69% stenosis,or =70% stenosis to near occlusion, near occlusion, and total occlusion. (c) ICA peak systolic velocity (PSV) and presence of plaque on gray-scale and/or color Doppler images are primarily used in diagnosis and grading of ICA stenosis; two additional parameters, ICA-to-common carotid artery PSV ratio and ICA end-diastolic velocity may also be used when clinical or technical factors raise concern that ICA PSV may not be representative of the extent of disease. (d) ICA should be diagnosed as (i) normal when ICA PSV is less than 125 cm/sec and no plaque or intimal thickening is visible; (ii)50% stenosis when ICA PSV is less than 125 cm/sec and plaque or intimal thickening is visible; (iii) 50%-69% stenosis when ICA PSV is 125-230 cm/sec and plaque is visible; (iv)or =70% stenosis to near occlusion when ICA PSV is greater than 230 cm/sec and visible plaque and lumen narrowing are seen; (v) near occlusion when there is a markedly narrowed lumen at color Doppler US; and (vi) total occlusion when there is no detectable patent lumen at gray-scale US and no flow at spectral, power, and color Doppler US. (e) The final report should discuss velocity measurements and gray-scale and color Doppler findings. Study limitations should be noted when they exist. The conclusion should state an estimated degree of ICA stenosis as reflected in the above categories. The panel also considered various technical aspects of carotid US and methods for quality assessment and identified several important unanswered questions meriting future research.

Radiologists interact with many individuals during daily practice, including patients, technologists, and other physicians. Some interactions may potentially negatively affect patient care and are termed "disruptive" behaviors. These actions are not uncommon and may begin during training, long before a radiologist enters clinical practice. The causes of disruptive behavior are multifactorial, and it is important that educators and radiologists in practice alike be able to identify them and respond accordingly. An escalated approach for both trainees and practicing radiologists is recommended, with substantial penalties after each incident that can include termination of employment. Training programs and practices must have clearly defined methods for confronting this potentially time-consuming and difficult issue.

Significant hepatic artery stenosis (HAS) after orthotopic liver transplantation (OLT) can lead to thrombosis, with subsequent liver failure in 30% of patients. Although operative intervention or retransplantation has been the traditional solution, endovascular therapy has emerged as a less invasive treatment strategy. Prior smaller studies have been conflicting in the relative efficacy of percutaneous transluminal angioplasty (PTA) vs primary stent placement for HAS.This was a single-center retrospective review of all endovascular interventions for HAS after OLT during a 54-month period (August 2009-December 2013). Patients with ultrasound imaging with evidence of severe HAS (peak systolic velocity400-450 cm/s, resistive index0.5) underwent endovascular treatment with primary stent placement or PTA. Outcomes calculated were technical success, primary and primary assisted patency rates, reinterventions, and complications.Sixty-two interventions for HAS were performed in 42 patients with a mean follow-up of 19.1 ± 15.2 months. During the study period, 654 OLTs were performed. Of 61 patients diagnosed with HAS, 42 underwent an endovascular intervention. The rate of endovascularly treated HAS was 6.4% (42 of 654). Primary technical success was achieved in 95% (59 of 62) of the interventions. Initial treatment was with PTA alone in 17 or primary stent in 25. Primary patency rates after initial stent placement were 87%, 76.5%, 78%, and 78% at 1, 6, 12, and 24 months, respectively, compared with initial PTA rates of 64.7%, 53.3%, 40%, and 0% (P = .19). There were 20 reinterventions in 14 patients (eight stents, six PTAs). The time to the initial reintervention was 51 days in patients with PTA alone vs 105.8 days for those with an initial stent (P = .16). Overall primary assisted patency was 93% at 24 months. Major complications were one arterial rupture and two hepatic artery dissections. The long-term risk of hepatic artery thrombosis in the entire patient cohort was 3.2%.HAS after OLT can be treated endovascularly with high technical success and excellent primary assisted patency. This series represents the largest reported cohort of endovascular interventions for HAS to date. Initial use of a stent showed a strong trend toward decreasing the need for reintervention. Avoidance of hepatic artery thrombosis is possible in95% of patients with endovascular treatment and close follow-up.

Purpose As part of the 2014 ACR Human Resources Commission Workforce Survey, an assessment of the gender of the U.S. radiologist workforce was undertaken. Radiologist gender in relation to type of practice, work location, leadership roles, and full- versus part-time employment have not previously been assessed by this survey. Methods The survey was completed by group leaders in radiology identified through the Practice of Radiology Environment Database. Results The response rate to the survey was 22%, representing 35% of all practicing radiologists. The survey found that 78% of the radiology workforce is male, and 22% female. Among the men, 58% work in private practice, and 18% in the academic/university environment; among women, percentages were 43% and 31%, respectively. Of all physician leads, 85% are men, 15% women. Of the full-time radiologists, 15% of men are practice leaders compared with 11% of women. Conclusions Fewer women than men are in private practice. More women than men practice in academic/university environments. Among part-time radiologists, there are more men than women, but significantly more women work part time than men. Women are in the minority among practice leaders.

Our specialty is seeking to establish the value of imaging in the longitudinal patient-care continuum. We recognize the need to assess the value of our contributions rather than concentrating primarily on generating revenue. This recent focus is a result of both increased cost-containment efforts and regulatory demands. Imaging 3.0 is a value-based perspective that intends to describe and facilitate value-based imaging. Imaging 3.0 includes a broad set of initiatives addressing the visibility of radiologists, and emphasizing quality and safety oversight by radiologists, which are new directions of focus for us. Imaging 3.0 also addresses subspecialty imaging and off-hours imaging, which are existing areas of practice that are emblematic of inconsistent service delivery across all hours. Looking to the future, Imaging 3.0 describes how imaging services could be integrated into the framework of accountable care organizations. Although all these efforts may be essential, they necessitate manpower expenditures, and these efforts are not directly covered by revenue. If we recognize the urgency of need in developing these concepts, we can justify the manpower and staffing expenditures each organization is willing to shoulder in reaching Imaging 3.0.

Endovascular stenting is a safe, effective treatment of hepatic artery stenosis after liver transplant, but no detailed evaluation has been completed of changes in ultrasound monitoring parameters after stenting. This study aims to improve poststenting surveillance by delineating the expected postoperative findings.Thirty-one stent procedures were performed at our institution for hepatic artery stenosis after liver transplant between October 2010 and October 2012. Of these, 28 (90%) were technically successful, of which 23 met the minimum follow-up time (76 days, defined by the earliest diagnosed restenosis). These patients were followed with serial ultrasound, per the following schedule: within 1 week of stenting, 3 months after stenting, 6 months after stenting, and every 6 months thereafter; additional, unscheduled examinations were frequently performed when indicated on the basis of deterioration of clinical and laboratory status. Follow-up examinations (mean, 268 days total follow-up) were compared with prestenting examinations to evaluate changes in peak systolic velocity (PSV), resistive index (RI), and tardus-parvus waveforms. Data were analyzed to determine a normal range for postprocedure values and time course of change in values.Of the 23 patients, six experienced restenosis. In all patients, mean PSV decreased by 124 cm/s, and mean RI increased by 0.13 within 48 hours after stenting. PSV differed between patency and restenosis groups only at more than 90 days after stenting (mean PSV, 234 and 400 cm/s, respectively), with PSV above 300 cm/s serving as a high-sensitivity threshold for the determination of restenosis. Prestenting RI of below 0.40 had a strong correlation with restenosis. Poststenting RI differed between patency and restenosis groups only at more than 48 hours after stenting, with RI of below 0.55 having a strong correlation with restenosis. Tardus-parvus waveform resolution was often delayed well beyond 48 hours after stenting, and time to tardus-parvus waveform resolution had no correlation with patency or restenosis.Ultrasound is convenient and useful to follow stents in hepatic artery stenosis after liver transplant. Prestenting hemodynamics can have value in predicting restenosis. Diagnosis of restenosis can be made with RI and PSV, whereas resolution time of tardus-parvus waveform is of less concern. These parameters can guide which patients require closer monitoring and aggressive treatment.

The employment of part-time radiologists (PTRs) has both advantages and disadvantages in various practice settings. The authors examine the pros and cons of PTRs and review the literature regarding PTRs both within and outside the specialty of radiology. The complexity of this issue is manifested in our inability to reach consensus on many policy issues for PTRs. Nevertheless, this article should be helpful in offering an objective, nonbiased background to initiating a discussion on employing PTRs in various radiology practices.
