Spontaneous suburothelial hemorrhage (SSH), also known as Antopol Goldman lesion, is a rare condition characterized by spontaneous bleeding into the renal sinus and proximal ureter wall. This case report describes the clinical presentation, imaging findings, and management of SSH in a 20-year-old female initially suspected to have urothelial malignancy. Imaging features of SSH include pre-contrast hyperdensity and non-enhancing thickening of the pelviureteric wall, which can mimic transitional cell carcinoma (TCC) and lead to unnecessary interventions. Radiologists should maintain a high level of suspicion for SSH and be aware of its imaging characteristics to avoid misdiagnosis. Additionally, clinical data, such as bleeding dyscrasia, can aid in the imaging diagnosis. This report provides insights into the diagnosis and management of SSH while offering a comprehensive literature review on its clinical presentation and imaging features. Increased awareness of SSH will facilitate accurate diagnosis and appropriate management, avoiding unnecessary interventions for patients with this benign condition. [ABSTRACT FROM AUTHOR]

BACKGROUND፡ The thyroid, along with the breast, lung, and bone marrow, is among the most radiosensitive organs. This study aims to assess the rate of unnecessary radiation exposure to the thyroid gland in patients who had chest Computed Tomography (CT) at a large teaching hospital. METHOD: Hospital-based retrospective cross-sectional study on 1,306 patients who underwent chest CT from July 2018 to January 2019. Thyroid gland inclusion along with the CT dose of the studies was evaluated. Data was collected by evaluating chest CT scans from Picture Archive and Communication System (MedWeb). RESULT: Out of 1306 patients, who had Chest CT scans intravenous iodinated contrast media was used in 95.4% of the CT scans. The thyroid was included in 99.8% of the scans, out of which 76.9% included the whole thyroid gland. Among the patients who had previous CT scans, 75.3% had one previous scan and 24.7% had two previous scans. DLP (Dose Length Product) in mGycm was lower in females (360.33±32) compared to males (426.45±378.4). The lowest DLP value was observed in the pediatric patients in the age range of 1-5 years which was 146.83, while the highest was observed among those above 18 years of age with mean DLP of 418.31. CONCLUSION: The majority of chest CT scans unnecessarily include the whole thyroid gland, which is one of the most sensitive organs for radiation-induced effects. Authors recommend optimized technique for chest scans to avoid future impacts. [ABSTRACT FROM AUTHOR]

BACKGROUND: Colorectal cancer (CRC) is one of the most prevalent and incident cancers worldwide with an Increasing prevalence in a younger age in developing countries. The aim of the study was to determine the staging and imaging pattern of CRC at diagnosis. METHODS: This is a descriptive cross-sectional study including all consecutive cases of CRC found in the departments of radiology and oncology during the study period from March 2016 - February 2017. RESULTS: A total of 132 CRC cases were studied with M: F = 2.4:1, mean age of 46yrs and 67.4%

BACKGROUND: Radiology has become one of the most sought out residency programs in the country attracting highly qualified candidates from all over the country. The objective of the study was to determine the attitude, practice and barriers of radiology residents towards academic research: Method: A descriptive cross-sectional survey was conducted across all five institutions currently giving radiology residency programs in the country the survey was carried out from 12/16/2020 to 12/12/2021. Using a questionaries' that were distributed to the residents using google docs. RESULTS: There were A total of 120 radiology residents participated in the study. 93(77.5%) of the participants were male while the rest 27 (22.5%) were female. With the mean age of the participants was 29 (1.75)years of age. Out of the 120 residents only 6 (5%) of them have published a research paper. 92.6% of the respondents were found to have a positive attitude towards academic research. Some of the major barrier to research identified by the study were the lack of time due to heavy workload, lack of Training course, inadequate Mentor Support and inadequate financial support. CONCLUSIONS: The study has showed that the overall attitude of radiology residents across the country towards academic research was positive but the practice of the residents in various academic research activities was found to be low. The authors recommend that all the stakeholders in radiology post graduate education to encourage residents in their academic pursuits by providing the necessary time and resources needed to perform quality research.

The practice of radiology began after the invention of X-rays in 1895 which then spread to different parts of the world. There is no documentation on how and when the x-ray was introduced to the Ethiopian medical practice. However, radiology as a profession was in place for the last four decades. Similar with the experience in other countries, the history of progress in the field of radiology in the Ethiopian setup is related directly to technological advances that occurred during the past few decades. Radiography was the main modality used in the first two decades. In the early years of the initiation of radiology training, only radiographs and ultrasounds were available for training and service. In the subsequent years, modern cross-sectional imaging equipment was introduced. This was mainly accomplished with the involvement of the private institutions which played a significant role. So far, there are more than 300 practicing radiologists as diagnosticians. Recently, also radiologic interventions were also introduced with the commencement of subspecialty training.

BACKGROUND: National and multinational surveys indicate large variability of Computed Tomography urinarytractStone doses. The wide use of abdominopelvic Computed Tomography in the diagnosis, raised the issue of radiation exposure. Hence, this study was conducted to assess Computed Tomography radiation exposure of urinary tract Stone Patients there by, to compare the results from established reference values and other published studies. METHODS: A retrospective cross-sectional was done on 100 urinary tract Stone patients who have at least one computed tomography scan as part of their follow-up or for diagnosis purposes fromFebruary 1 to May 31, 2021, at Tikur Anbesa Specialized Hospital. Data were collected using a structured questionnaire format that evaluates the number of Computed Tomography they had, scan parameters, dose indicators, and socio-demographic characteristics. Finally, the collected data were analyzed using statistical software SPSS version 22. RESULTS: Out of 100 patients 3.6%of our patients have radiation exposure of more than 4mSv, which is the standard for low-dose Computed Tomography. The median radiation exposure is 1.27mSv per scan. Exposure factors like tube current, tube current products, dose length product, and scan range all have similar values with an almost null interquartile range. All the scans that overpassed the low dose threshold(4mSv) were done outsideTikur Anbesa Specialized Hospital. CONCLUSION: Our study showed that Tikur Anbesa Specialized Hospital's low-dose CT protocol for patients with urinary tract Stone is well optimized as opposed to non-Tikur Anbesa Specialized Hospital.
