Injuries to the hand and digits are common in football players. To our knowledge, there have been no reports on multiple flexor pulley ruptures in football players treated non-operatively through splinting and taping techniques. A 22-year old collegiate defensive lineman sustained an injury resulting in complete disruption of the annular 2, 3, 4, and cruciate 1 and 2 pulleys. The patient was successfully treated with serial custom splints for 12 weeks. Our splinting and taping techniques and timing of these have not been previously described. This case illustrates a successful treatment option in football players with multiple flexor pulley ruptures.

Diseases of the musculoskeletal system ,RC925-935 - Abstract
Polyfibromatosis is a rare disease characterized by fibrosis manifesting in different locations. It is commonly characterized by palmar fibromatosis (Dupuytren’s contracture) in variable combinations with plantar fibromatosis (Ledderhose’s disease), penile fibromatosis (Peyronie’s disease), knuckle pads, and keloids. There are only three reported cases of polyfibromatosis and keloids with erosive arthritis. We report one such case and review the existing literature on this rare syndrome.

The Kaizen method is an approach to lean process improvement that is based on the idea that small ongoing positive changes can lead to major improvements in efficiency and reduction of waste. The hospital-based CT division at Mayo Clinic Arizona had been receiving numerous concerns of delays in the performance of examinations from inpatients, outpatients, and patients presenting to the emergency department. These concerns, along with a planned hospital expansion, provided the impetus to perform a process improvement project with the goal of reducing inpatient, emergency department, and outpatient turnaround times by 20%. Kaizen process improvement was chosen because of the emphasis on reduction of waste, standardization, and empowerment of frontline staff. The project was led by a process improvement coach who was trained in lean process improvement and A3 thinking. At the end of a weeklong Kaizen event, inpatient turnaround time decreased by 54%, emergency department turnaround time decreased by 29%, and outpatient turnaround time decreased by 45%. These results were achieved and sustained by establishing standardized work, developing frontline problem solvers, instituting visual management, aligning with relevant metrics, emphasizing patient and staff satisfaction, and reducing lead time and non-value-added work. When done properly, a Kaizen event can be an effective tool for process improvement in the health care setting.

The purpose of this article is to present algorithms for the diagnostic management of solitary bone lesions incidentally encountered on computed tomography (CT) and magnetic resonance (MRI) in adults. Based on review of the current literature and expert opinion, the Practice Guidelines and Technical Standards Committee of the Society of Skeletal Radiology (SSR) proposes a bone reporting and data system (Bone-RADS) for incidentally encountered solitary bone lesions on CT and MRI with four possible diagnostic management recommendations (Bone-RADS1, leave alone; Bone-RADS2, perform different imaging modality; Bone-RADS3, perform follow-up imaging; Bone-RADS4, biopsy and/or oncologic referral). Two algorithms for CT based on lesion density (lucent or sclerotic/mixed) and two for MRI allow the user to arrive at a specific Bone-RADS management recommendation. Representative cases are provided to illustrate the usability of the algorithms.

Purpose This article describes an innovative technique to confirm needle tip positioning using digital subtraction fluoroscopy and air within a targeted joint. Materials and Methods Digital subtraction fluoroscopy with air was utilized to confirm intra-articular needle tip position in 12 joints over a 14-month period at a single institution. Procedural details were recorded for each joint including: joint location, fluoroscopy time, patient age, patient body mass index, and change in subjective pain rating following the injection. Shoulder and hip phantoms were utilized to compare radiation dose differences between fluoroscopy with digital subtraction technique and fluoroscopy without digital subtraction technique. Results All of the 12 injections were technically successful with air clearly visualized within each targeted joint and subjective pain ratings either did not change or decreased following the injection. Patient age ranged from 51 to 87 years old and body mass index values ranged from 19.2 to 37.1 kg/m2. Fluoroscopy times ranged from 11.1 to 32.9 seconds. There were no complications during or immediately following the injections. The addition of digital subtraction technique increased the skin dose at the shoulder by approximately 2.6 times and at the hip by approximately 2.2 times. Likewise, the cumulative dose at the shoulder increased by approximately 2.7 times and at the hip by 2.0 times. Conclusion Fluoroscopic digital subtraction air arthrography is a valuable option for needle tip confirmation when using air as a contrast agent. This novel combination of established fluoroscopic techniques can be incorporated into most clinical practices.

We report a case of a 19-year-old man who presented with severe scrotal swelling. His medical history was notable for severe global edema at birth. Most areas of swelling had resolved by adolescence with exception of the scrotum and the left lower extremity. 99mTc-filtered sulfur colloid lymphoscintigraphy of the lower extremities demonstrated prominent dermal backflow into the superficial scrotum and thighs, which were confirmed on the SPECT/CT images, and correlated with findings on MR lymphangiogram. Lymphoscintigram and MR lymphangiogram may provide complementary information to aid diagnosis and management of primary scrotal lymphedema.

Improper specimen labeling of biopsy samples can cause substantial harm to patients through diagnostic delays, administration of inappropriate treatments, and can result in a loss of trust in the healthcare system. Specimen labeling errors are considered a relevant safety metric in our department and tracked on a rolling basis. One imaging section was noted to have nearly completely eliminated these errors through implementation of a 2-person check prior to submission to pathology. The purpose of this intervention was to identify the causes of continued specimen labeling errors in radiology and to standardize the specimen labeling workflow across the department of radiology to include the best practice identified in breast imaging utilizing a 2-person check. Preintervention, 31 specimen labeling errors were reported by the procedural staff over a period of 149 weeks resulting in an error rate of 0.21 errors per week. Postintervention, 3 specimen labeling errors occurred in the next 46 weeks resulting in a rate of 0.07 errors per week, a 68.8% decrease in the specimen labeling error rate. This quality improvement project highlights the process flaws which contribute to medical errors and demonstrates a potential pathway to try and reduce these errors and patient harm without significant investment in capital or new technology.

The purpose of this study was to compare the utility of two-dimensional high-resolution (2D), 3-dimensional with multiplanar reconstruction (3D MPR), and radially reformatted (RR) MRIs when evaluating the complexities of the hip joint in patients with femoroacetabular impingement (FAI). We hypothesized RR would be superior in detecting labral pathology and 2D would be superior in detecting transition zone and acetabular cartilage injury. 2D, 3D MPR, and RR MRIs of 33 patients, who later underwent surgical treatment for FAI, were evaluated for sensitivity, specificity, and accuracy. Bland-Altman methods were used to estimate agreement between each method and the gold-standard, arthroscopic visualization of the hip joint, regarding the percentage of the hip joint affected by each injury type. 3D MPR and RR groupings were associated with the highest sensitivity and accuracy for labral injury. 3D MPR demonstrated the smallest bias in assessing the percentage of joint affected by labral injury and was the most accurate in identifying acetabular cartilage injury, whereas RR had the smallest mean difference in assessing the percentage of joint affected by acetabular cartilage injury. 2D was the most accurate in identifying transition zone injuries, while RR was superior in assessing the percentage of the joint affected by transition zone injury. Our results suggest that including both 3D MPR and RR MRI groupings is favorable for accurate joint visualization and well-informed treatment planning, especially given that labral injury is a main source of pain and dysfunction for FAI patients.

Intraosseous infusion has become a key tool in the resuscitation of critically ill or injured patients, both in pre-hospital settings and in emergency departments. Intraosseous access is obtained through the percutaneous placement of a needle into the medullary space of a bone, thereby allowing access into the systemic venous circulation via the medullary space, which is essential to treat patients in shock, cardiac arrest, airway compromise, or major trauma. This becomes critically important when obtaining conventional intravenous access is difficult or impossible. Few cases of iatrogenic fracture have been reported for intraosseous access in the tibia and no case to-date has been reported of iatrogenic fracture secondary to humeral access. We report a case of a 55-year-old patient being resuscitated emergently with proximal humeral intraosseous infusion for cardiac and respiratory arrest secondary to status epilepticus. After successful resuscitation and removal of the intraosseous cannula, the patient noted new-onset shoulder pain. The patient was ultimately diagnosed with an iatrogenic fracture of the anatomic neck of the humerus through the intraosseous needle tract when the appropriate history was obtained in conjunction with cross-sectional imaging. As the use of intraosseous access expands, such fractures may well be seen more frequently. Intraosseous access is limited to the period of resuscitation and the cannula is often not present at the time of imaging. It is important for radiologists to recognize the findings related to intraosseous access as well as this complication with its characteristic locations and morphology.

Objective To review current musculoskeletal (MSK) job market postings to define the listed requirements for practice in order to provide insight to guide residents pursuing fellowship training in MSK radiology to best meet the needs of potential future employers. Methods Utilizing the ACR (American College of Radiology) Career Center, a review of the ACR job postings began 6/1/2018 focusing on jobs labeled as musculoskeletal (MSK) subspecialty. E-mail notifications from the career center were reviewed, and jobs were tracked prospectively for 1 year. Data was collected regarding the number of positions, the location, the practice type, and required skills both within musculoskeletal radiology and within the remainder of the radiology subspecialties. Results 456 postings met the inclusion criteria. Approximately 19% were for a dedicated MSK radiologist, 25% sought a combination of MSK and a general skill set, and 56% were specifically for a general radiologist position. Approximately 29% of jobs require some combination of mammography and/or light interventional radiology (IR). Discussion Our results indicate that majority of job postings for musculoskeletal radiology require a practice that is not specifically limited to MSK, mirroring trends in other radiology subspecialties. Radiology trainees and program directors should be aware of the needs being demanded by the job market to help guide trainees to individualize their training to best meet the needs of their future employment.

Rationale and Objectives Departmental websites are often the first exposure applicants have in researching programs. Websites provide information about resident education as well as infrastructure for resident wellness. For this study, we reviewed residency websites to evaluate resident wellness initiatives and extent of details available online. Materials and Methods Program websites for diagnostic radiology residencies listed in the 2020 ERAS program list were evaluated for 26 criteria pertaining to resident wellness. Criteria which are not radiology resident specific were also evaluated on their graduate medical education (GME) websites if unavailable on the departmental website. Results Of 189 programs, 185 (97.9%) had functioning websites for review. Book funds were mentioned by 57% (mean $3,762), and 43.5% discussed housing stipends during AIRP (mean $2,204); neither significantly correlated with program size. Retirement plan matching was present for 47.8% of programs. Almost all programs utilized night float call schedules, with relatively similar distribution of residents starting on-call duties as fall PGY2s, spring PGY2s, and starting PGY3s. Moonlighting was mentioned by 22.8% of departments. Paid wellness days were discussed in 10.8% (mean 3.1 days/year), and 37.7% described paid parental leave (mean 27.8 days/year). Less than 10% described resident mentoring, wellness committees, or non-clinical curricula. Resident retreats were mentioned by 21.6% of programs, and 11.4% described regular social activities; both were found more frequently at larger programs (chi-square analysis, p Conclusion This study evaluated radiology residency program and GME websites for information pertaining to resident wellness. While financial and clinical information was typically present for >50% of programs, information regarding social initiatives was generally lacking and may be one area to bolster resident wellness and describe on websites.

A broken needle is a rare complication of bone biopsy. We describe an easily applied technique of retrieval of a retained biopsy needle fragment using a cannulated drill typically used for internal fixation of femoral neck fractures. This approach allows for removal under moderate conscious sedation and can be performed by a radiologist using fluoroscopic or CT-fluoroscopic guidance in the radiology suite.

Purpose To evaluate the relationship between use of MRI of the lumbar spine for low back pain without prior conservative therapy and sociodemographic factors after the implementation of public reporting for Medicare's Hospital Outpatient Imaging Efficiency Measure for MRI Lumbar Spine for Low Back Pain (OP-8) metric. Materials and Methods We conducted a secondary data analysis using a nationally representative sample of 2009 to 2014 Medicare claims to evaluate trends in use of conservative therapy before MRI of the lumbar spine. Continuously enrolled fee-for-service Medicare beneficiaries were included. We applied the same criteria used by Medicare to generate a measure consistent with OP-8. Regression was used to evaluate trends in OP-8 by reporting status (outpatient hospital or clinic) and beneficiary characteristics. Age, sex, and race from the Medicare denominator and area-level socioeconomic measures from the Area Health Resource File were used as covariates. Results Use of conservative therapy before MRI increased regardless of OP-8 reporting status. Several sociodemographic characteristics were associated with the likelihood of receiving conservative therapy before MRI; beneficiaries were less likely to receive conservative therapy before MRI if they were male, older, black, Hispanic or Latino; if they lived in the West or in an area with more college graduates; or if they had low incomes. Beneficiaries were more likely to receive conservative therapy before MRI if they had poorer health or lived in areas with higher home values. Conclusion Variations in use of conservative therapy according to factors other than clinically relevant factors, such as health status, are worrying. Further strategies are needed to improve appropriateness and equity in the provision of diagnostic imaging.

Background A chimerically configured gracilis and profunda artery perforator (PAP) flap is highly prevalent based on recent computed tomography (CT)-imaging data. The purpose of this study is to further characterize the vascular anatomy of this novel flap configuration and determine the feasibility of flap dissection. Methods To characterize flap arterial anatomy, lower extremity CT angiograms performed from 2011 to 2018 were retrospectively reviewed. To characterize venous anatomy and determine the feasibility of flap harvest, the lower extremities of cadavers were evaluated. Results A total of 974 lower extremity CT angiograms and 32 cadavers were included for the assessment. Of the 974 CT angiograms, majority (966, 99%) were bilateral studies, yielding a total of 1,940 lower extremities (right-lower-extremity = 970 and left-lower-extremity = 970) for radiographic evaluation. On CT angiography, a chimerically configured gracilis and PAP flap was found in 51% of patients (n = 494/974). By laterality, chimeric anatomy was present in 26% of right lower extremities (n = 254/970) and 25% of left lower extremities (n = 240/970); bilateral chimeric anatomy was found in 12% (n = 112/966) of patients. Average length of the common arterial pedicle feeding both gracilis and PAP flap perforasomes was 31.1 ± 16.5 mm (range = 2.0–95.0 mm) with an average diameter of 2.8 ± 0.7 mm (range = 1.3–8.8 mm).A total of 15 cadavers exhibited chimeric anatomy with intact, conjoined arteries and veins allowing for anatomical tracing from the profunda femoris to the distal branches within the tissues of the medial thigh. Dissection and isolation of the common pedicle and distal vessels was feasible with minimal disruption of adjacent tissues. Chimeric flap venous anatomy was favorable, with vena commitante adjacent to the common pedicle in all specimens. Conclusion Dissection of a chimeric medial thigh flap consisting of both gracilis and PAP flap tissues is feasible in a cadaveric model. The vascular anatomy of this potential flap appears suitable for future utilization in a clinical setting.

OBJECTIVE. We undertook this study to determine the radiologic features of desmo-plastic fibroblastoma. MATERIALS AND METHODS. We reviewed available radiologic images for 29 pathologically confirmed desmoplastic fibroblastomas, including images from MRI, radiography, ultrasound (US), and CT. RESULTS. The patient population included 14 women and 15 men (mean age, 60 years; range, 23-96 years). Typically, lesions were oval or lobulated and relatively small (mean, 5.6 cm). In 14 of the 22 cases that included patient histories, lesions had grown slowly, with two eventually causing pain. The remaining eight were discovered incidentally. All lesions involved or were below the deep fascia. Lesions were well-defined and associated with muscle (45%), deep fascia (28%), joint (21%), or tendon (7%). MR images were available in 26 cases; 14 included unenhanced and contrast-enhanced studies. On MRI imaging all lesions were well-defined and adjacent to dense connective tissue. On T1-weighted images, lesions showed varying amounts of low and intermediate signal intensity similar to that of tendon and skeletal muscle, respectively. On fluid-sensitive images, lesions were more heterogeneous, generally showing a wider spectrum of decreased to intermediate signal intensity. On contrast-enhanced MR images, enhancement was characteristically peripheral and septal with patchy areas of homogeneity. In the 10 cases with radiographs, images showed negative findings or a nonmineralized mass. The 10 available ultrasound studies showed mixed echogenicity. In eight patients, unenhanced CT showed lesions having attenuation similar to that of skeletal muscle. CONCLUSION. Desmoplastic fibroblastoma is an uncommon neoplasm with a relatively characteristic MRI appearance.

Injuries to the hand and digits are common in football players. To our knowledge, there have been no reports on multiple flexor pulley ruptures in football players treated non-operatively through splinting and taping techniques. A 22-year old collegiate defensive lineman sustained an injury resulting in complete disruption of the annular 2, 3, 4, and cruciate 1 and 2 pulleys. The patient was successfully treated with serial custom splints for 12 weeks. Our splinting and taping techniques and timing of these have not been previously described. This case illustrates a successful treatment option in football players with multiple flexor pulley ruptures.

Funding for research has become increasingly difficult to obtain in an environment of decreasing clinical revenue, increasing research costs, and growing competition for federal and nonfederal funding sources. This paper identifies critical requirements to build and sustain a successful radiology research program (eg, key personnel and leadership, research training and mentorship, infrastructure, institutional and departmental funding or support), reviews the current state of available funding for radiology (including federal, nonfederal, philanthropy, crowdfunding, and industry), and describes promising opportunities for future funding (eg, health services, comparative effectiveness, and patient-centered outcomes research). The funding climate, especially at the federal level, changes periodically, so it is important to have radiology-specific organizations such as the American College of Radiology and the Academy of Radiology Research serving as our key advocates. Key to obtaining any funding, no matter what the source, is a well-formulated grant proposal, so a review of opportunities specifically available to radiologists to develop and hone their grant-writing skills is provided. Effective and sustained funding for radiology research has the potential to cultivate young researchers, bolster quality research, and enhance health care. Those interested in pursuing research need to be aware of the ever-changing funding landscape, research priority areas, and the resources available to them to succeed. To succeed, radiology researchers need to think about diversification and flexibility in their interests, developing multidisciplinary and multi-institutional projects, and engaging a broader base of stakeholders that includes patients.

OP-8 is the Medicare imaging efficiency metric for MRI of the lumbar spine for low back pain in the outpatient hospital. We studied trends in exclusion criteria coding over time by site of service after implementation of OP-8 to evaluate provider's response to public reporting.We conducted a secondary data analysis using the Medicare Limited Data Set 5% sample for beneficiaries with MRI lumbar spine and lower back pain during 2009 to 2014. We evaluated the association between excluding condition prevalence and site by using generalized estimating equations regression. We produced model-based estimates of excluding condition prevalence by site and year. As a sensitivity analysis, we repeated the analysis while including additional conditions in the outcome measure.We included 285,911 MRIs of the lumbar spine for low back pain. Generalized estimating equations regression found that outpatient hospitals had a higher proportion of MRIs with at least one excluding condition documented compared with outpatient clinics (P.05), but increases in excluding condition prevalence were similar across all sites during 2009 to 2014. Our results were not sensitive to the inclusion of additional conditions.Documentation of excluding conditions and other clinically reasonable exclusions for OP-8 increased over time for outpatient hospitals and clinics. Increases in documentation of comorbidities may not translate to actual improvement in imaging appropriateness for low back pain. When accounting for all relevant conditions, the proportion of patients with low back pain considered uncomplicated and being measured by OP-8 would be small, reflecting a small proportion of patients with low back pain.

The purpose of this investigation was to better define the anatomical features of the biceps tendon sheath, including the distance the sheath extends below the inferior margin of the subscapularis tendon and below the termination of the bony bicipital groove. A total of 110 magnetic resonance and computed tomography arthrograms performed during 1-year period at our institution were retrospectively reviewed, and the length of the biceps tendon sheath and distances from the inferior margin of the subscapularis tendon and from the termination of the bicipital groove to the inferior margin of the biceps tendon sheath were measured by 3 radiologists. The mean length of the biceps tendon sheath was 47.5mm. The mean distances from the inferior margin of the subscapularis tendon and from the inferior margin of the bicipital groove to the distal extent of the biceps tendon sheath were 24.5mm and 11.9mm, respectively. The relationships among these 3 anatomical measurements and biological confounders of sex and age were investigated while controlling for measurement variability. The anatomical relationships between the biceps tendon sheath and surrounding structures may have implications for needle placement when attempting to inject into the biceps tendon sheath for diagnostic or therapeutic purposes.

MRI remains the optimal imaging modality to evaluate cartilage injuries in the athlete. As these injuries have no intrinsic healing capacity, early and accurate noninvasive diagnosis remains integral to determining the most appropriate treatment option in this class of patients. Although surgical success depends primarily on clinical outcomes, MRI evaluation can provide pertinent information regarding the status of the surgical repair and the progression of cartilage disease.

Purpose Radiology fellowship training has evolved from being an uncommon option to being a near requisite for post-training employment in the United States. A subset of fellows elect to pursue second fellowships with potentially substantial implications on both the private sector and academic radiology workforce. The purpose of this study was to assess the proportion of current radiology fellows pursuing multiple years of post-residency fellowship training. Materials and Methods After obtaining IRB approval, an anonymous web-based survey was emailed to 1,269 radiology fellows listed as “completing fellowship” in the American College of Radiology database in June 2014. Questions were asked regarding current fellowship training, post-fellowship employment plans, and individual experience pursuing employment. Results were analyzed using the survey analytical software. Results There were 219 responses received, representing a 17.3% response rate. Ten-percent of respondents were currently completing their second radiology fellowship. Of those completing their first year of fellowship training, 11% indicated plans to complete a second radiology fellowship. Conclusion This survey provides a snapshot of the percentage of radiology trainees who pursue a second year of fellowship training, currently in the range of 10%. Pursuing a second radiology fellowship may represent a safety net to a substantial subset of fellows who are not able to obtain satisfactory employment following training. Academic programs who rely heavily on fellows should be aware of the proportion of fellows pursuing two fellowships and should be prepared to adapt should this change over time.

Radiology residency training has undergone substantial changes, including increased utilization of night float systems, late and/or overnight attending radiology in-house coverage (LOAR), and restructuring of the radiology boards. The purpose of this study is to evaluate radiology residents' perceptions regarding these changes and their impact on resident training using an anonymous, web-based survey that was distributed to radiology residents across the United States. A total of 345 current radiology residents completed the survey. A substantial number of radiology residents perceive that LOARs have negative impact on their development of independence and efficiency during the on call period. Residents are concerned about the timing of the core exam and match fellowship interviews, the timing of the certifying exam, and that graduating as board-eligible radiologists will harm their job search.

Background Novel secondary flap options are paramount for patients who are not candidates for common reconstructive methods. The purpose of this study is to identify the prevalence of single arterial pedicle supplying both the gracilis muscle and medial thigh tissue carried in a profunda artery perforator (PAP) flap. Such a pedicle could allow the creation of a chimeric gracilis and PAP flap with a single-arterial anastomosis. Methods We conducted a retrospective review of 157 lower extremity computed tomography (CT) angiograms to assess the vasculature of the thigh soft tissues. Imaging evaluation was supervised by a board-certified musculoskeletal radiologist. Results Prevalence of a single-arterial pedicle to a gracilis and PAP flap in each patient was 59% (31% within the right leg and 28% in the left leg). Furthermore, 16% of patients had a common arterial pedicle in both lower extremities. Conclusion Existence of a single-arterial pedicle to both the gracilis muscle and PAP flap tissues is frequently present in most patients in at least one lower extremity. This chimeric flap configuration could serve as a reconstructive avenue for patients, particularly those who have exhausted other more common flap options. Screening angiography is warranted in patients looking for this anatomic variation to establish its presence.

To investigate the correlation between femoroacetabular cartilage thickness and lateral acetabular coverage in patients undergoing hip arthroscopy for a variety of indications. Articular cartilage at the hip is hypothesized to undergo adaptive change secondary to unique patterns of pathomechanical loading which results in a direct relationship between acetabular coverage and femoroacetabular cartilage thickness. A cohort of 252 patients presenting to our dedicated hip preservation service between June 2013 and June 2015 were retrospectively analysed. Preoperative radiographs and MRI studies were obtained for all symptomatic hips and classified according to radiographic lateral center edge angle (LCEA) as follows: normal acetabular coverage (25–40°), acetabular overcoverage (≥40°), borderline dysplasia (20–24.9°) and frank dysplasia (

Osteoarthritis of the hip remains a prevalent disease condition that influences ever-changing treatment options. Procedures performed to correct anatomic variations, and, in turn, prevent or slow the progression of osteoarthritis, are aptly referred to as types of hip preservation surgery (HPS). Conditions that predispose individuals to femoroacetabular impingement (FAI), including pincer- and cam-type morphology, and hip dysplasia are specifically targeted in HPS. Common surgical interventions include acetabuloplasty, osteochondroplasty, periacetabular osteotomy (PAO), and derotational femoral osteotomy (DFO). The radiologist's understanding of the surgical approach, pre- and postoperative imaging findings, and common complications of HPS are paramount to providing value to the patient and surgeon. Acetabuloplasty and osteochondroplasty are performed to address pincer- and cam-type morphology in patients with FAI. With both of these HPS techniques, the goal is to restore the normal morphology by resecting excess bone in the acetabulum or femoral head or neck. As a result, a frequently encountered complication is incomplete or excessive resection. Excessive resection can predispose the patient to dislocation in the case of acetabuloplasty and fracture in the case of osteochondroplasty. Iatrogenic injury to adjacent structures such as the ischiofemoral ligament and acetabular cartilage also may occur. Although rare, especially when an arthroscopic approach is used, avascular necrosis remains a risk. Femoral head undercoverage in hip dysplasia is corrected by using PAO, which may be performed as the sole procedure or in conjunction with DFO. Incomplete or excessive rotation during surgery can result in postprocedural complications. As with any orthopedic procedure involving osteotomy, nonhealing is a risk. Iatrogenic injury in the form of fracture or hardware failure also may be seen. ©RSNA, 2016.

Over the past 10 years, there has been increased attending-level image interpretation during what has typically been considered the on-call period. The purpose of this study is to survey radiology attending physicians and assess their perceptions about how the presence of radiology attending physicians during the on-call period affects patient care and resident education. Two hundred eighty-eight radiology attendings completed the online survey. 70% believe that after hours final reads by radiology attendings improves patient care. 56% believe that this additional attending presence has a negative impact on the ability of graduating residents to efficiently interpret studies independently. A majority of radiology attending physicians in this study believe that increased in-house radiology attending coverage is harming resident training across the United States, yet also believe this attending presence is important for patient care. Additional studies are needed to quantify and further evaluate this effect, and develop strategies to address potential negative impacts on radiology resident education.

The relative value unit (RVU) is an important measuring tool for the work performed by physicians, and is currently used in the United States to calculate physician reimbursement. An understanding of radiology RVUs and current procedural terminology codes is important for radiologists, trainees, radiology managers, and administrators, as this knowledge would help them to understand better their current productivity and reimbursement, as well as controversies regarding reimbursement, and permit them to adapt to reimbursement changes that may occur in the future. This article reviews the components of the RVU and how radiology payment is calculated, highlights trends in RVUs and resultant payment for diagnostic and therapeutic imaging and examinations, and discusses current issues involving RVU and current procedural terminology codes.

The term never event in medicine was originally coined by Kenneth W. Kizer, MD, MPH, former chief executive officer of the National Quality Forum, to describe particularly shocking medical errors that should never occur, such as wrong-site surgery or death associated with introduction of a metallic object into the MRI area. With time, the National Quality Forum's list of never events, or "serious reportable events," has been expanded to include adverse events that are unambiguous, serious, and usually preventable. In this article, the never event framework has been used to describe (a) the errors that may occur in an imaging department that are serious and usually preventable with a review of the causative factors and (b) strategies to eliminate and reduce the adverse effects of these avoidable errors. These errors are often rooted in communication breakdowns and can only be eliminated with a true shift to a culture of open reporting and patient safety. ©RSNA, 2018.

Purpose To evaluate current and recent interventional radiology (IR) fellows’ perceptions on the new integrated IR residency. Materials and methods An anonymous, web-based survey was distributed to 82 current and recent IR fellows across the Unites States. The survey contained 15 questions, most of which were based on a five-point Likert scale. The survey was open for a three-week period in September 2015. The results were analyzed by two trainees and three IR attending physicians. Results Sixty-four current or recent former IR fellows completed the survey (response rate 78%). Of these 18% decided to pursue a career in IR by the end of their third year of medical school. A majority believed that the integrated IR residency will be an improved IR training pathway (62%). Based on current medical school curricula, 74% either disagreed or strongly disagreed that IR residency applicants will be ready to select such a pathway by the end of their third year of medical school. Conclusions Most current and recent IR fellows surveyed chose IR during their final year of medical school or during residency. Most respondents believe that the integrated IR residency will be an improved IR training pathway.

We developed a faculty professional development seminar series in order to facilitate the integration of our numerous new faculty into academics. The changing nature of the healthcare system, increasing clinical and administrative responsibility, and lack of access to senior mentors can hinder junior faculty productivity and possibly increase attrition. Given that no ready-made resources existed to address these issues we established a Professional Development Committee, developed a curriculum that covers relevant topics including promotion, mentorship, conflict management and feedback, and effective presentation of scientific data, and instituted changes iteratively based upon feedback. We used surveys from successive years of this seminar series to assess effectiveness, and our data demonstrate that our Professional Development Seminar Series was valued by its participants and that individual lectures improved from year to year. While it is too early to determine whether our efforts will lead to long-term changes in promotion success or faculty retention, our initial data are promising.

The field of diagnostic and therapeutic radiology has always been characterized by constant innovation and creativity to evolve to its current form. There are numerous imaging techniques that were once prevalent but have become outdated and were replaced by the current examinations and modalities, which improve diagnostic accuracy and patient outcomes. Many of these outdated examinations were first described in the journal Radiology during its first 100 years of existence and were subsequently able to be disseminated across its vast readership to become the standard of care across the nation and the world. These earlier techniques, such as pneumoencephalography as it applies to neuroimaging and neurosurgery; kymography, a predecessor of cardiac imaging; contrast agents such as Thorotrast; and miscellaneous cultural tools, such as the shoe-fitting fluoroscope, left lasting impressions on the current practice of radiology and reflect a small subset of the imaging examinations of our predecessors. Knowledge of historic radiologic examinations and procedures is important to understand how we have arrived at the current practice of radiology we embrace today and how our field can continue to evolve to improve our diagnostic and therapeutic abilities to fit the changing needs of our patients.

Introduction Knee osteoarthritis (OA) is a degenerative form of arthritis commonly diagnosed in older adults. It presents clinically with patient complaints of pain and impaired function, which are thought to result from cartilage degeneration and other skeletal changes. These changes can by examined radiographically and quantified using the semiquantitative grading scale known as the Kellgren-Lawrence (KL) scale. Currently, no standard training exists for KL grading, which may explain the unsatisfactory reliability of this tool in OA research. Therefore, the objective of this project was to develop a training tutorial for KL grading of knee OA to educate assessors on possible areas of inconsistency in grading. Methods The tutorial was developed in an e-learning authoring tool, Articulate Presenter. The content focuses on the poor reliability of KL grading, normal anatomy of a knee radiograph, and multiple examples of bony changes within the knee and their relation to different grades of the KL scale. The tutorial was presented to a group of health sciences graduate students at the University of Colorado Denver. Results Students were able to complete the training and an associated assessment in under an hour and reported improved confidence with assessing radiographic knee OA. Furthermore, they demonstrated favorable inter- and intrarater reliability scores in applying KL grading. Discussion To our knowledge, this is the first attempt to standardize training in KL grading for knee OA and to examine the effects of this training on reliability.

Background: Vertebral augmentation (VA) performed on inpatients with painful osteoporotic vertebral compression fractures (VCFs) has been shown to facilitate discharge, decrease analgesic requirements, and improve pain. Objective: The purpose of our study was to compare the overall cost, length of stay, and readmission data for patients hospitalized with painful osteoporotic VCFs, treated either medically or with inpatient VA. Setting: A single academic medical center. Study Design: Economic analysis Methods: Patients admitted with VCF over a 30-month period were identified using ICD-9 codes. The total length of stay, hospitalization costs, average daily cost, and 30-day readmission rates were compared between those who underwent VA and those managed nonoperatively. A subgroup analysis was performed with an age matched group of controls as well. Two-tailed t-tests were used for statistical significance. Results: Thirty-nine inpatients underwent VA; 61 levels were augmented. Their average age was 81.7 years. There were 209 patients who were treated nonoperatively for VCF. Their average age was 72.7 years, a significant age difference from the VA group (P < 0.01). The VA patients’ average length of stay was 13.8 days, compared to 8.1 days in the medically managed group (P < 0.01). Average total costs were $26,074 in the VA group and $15,507 in the medically managed group (P < 0.01). The daily costs of admission were $2,040 in the VA group and $2,069 in the medically managed group (P = 0.85). The readmission rates related to VCF were 0% in the VA group; 5.2% in the medically managed group; and 7.7% in the agematched control group. Of those who underwent VA, 43% experienced delays in care related to anticoagulation or medical comorbidities. Limitations: The study is retrospective and uses billing data as a marker for total cost of care, The study does not account for cost differences between vertebroplasty and kyphoplasty. Conclusion: Inpatient VA can be cost effective as demonstrated by the same daily cost between the VA and medically managed groups. Early identification and consultation can facilitate VA and rapid discharge. Anticoagulation issues and medical comorbidities can delay VA and lengthen hospital stays. Hospital admitted patients with painful osteoporotic VCF who are managed conservatively and discharged are at risk for readmission. Key words: vertebral augmentation, osteoporotic vertebral compression fracture, vertebroplasty, kyphoplasty
