Non-interventional Radiology Fellowship Programs: What Is Out There?
Curr Probl Diagn Radiol
October 2021
Objective: To determine the spectrum of non-interventional radiology fellowship programs in institutions that offer both a radiology residency program and one or more non-interventional radiology fellowship programs.
Methods: Institutions offering both radiology residency and non-interventional radiology fellowship programs were identified using publicly available websites. The non-interventional radiology fellowship programs were categorized into "traditional" (neuroradiology, breast imaging, abdominal imaging, musculoskeletal imaging, thoracic imaging, pediatric radiology, and nuclear medicine) and "nontraditional" fellowship programs.
Imaging plays a central role in the postoperative management of acromioclavicular (AC) joint separations. There are more than 150 described techniques for the surgical management of AC joint injuries. These procedures can be categorized as varying combinations of the following basic techniques: a) soft-tissue repair, b) trans-articular AC joint fixation, c) coracoclavicular (CC) fixation, d) non-anatomic reconstruction of the CC ligaments, e) anatomic reconstruction of the CC ligaments, f) distal clavicle resection, and g) dynamic muscle transfer.

- The study explored the occurrence of contrast material extending from the radiocarpal joint into the soft tissues near the ulnar aspect of the wrist in MR arthrograms, hypothesizing that this finding is common and not related to symptoms.
- Out of 99 wrist examinations reviewed, 57% showed ulnar-sided contrast extravasation, which was more frequent in right wrists, but no other significant associations with wrist pain or joint abnormalities were found.
- The conclusion emphasized that such contrast extravasation is common following single-compartment radiocarpal joint injections and is not linked to the patients' reported symptoms or designed evaluation techniques.
Rib fractures are the most common form of blunt thoracic injury. Multiple rib fractures are an important indicator of trauma severity, with increased morbidity and mortality occurring with increasing numbers of rib fractures, especially in the elderly. Thoracic cage injuries may be associated with concomitant and potentially life-threating injuries.

- Anterior cruciate ligament (ACL) reconstruction is a widely performed surgery that has become more common in the last ten years.
- Different fixation devices are used to secure grafts in the femur and tibia during this procedure.
- Knowing how these devices look on post-operative images and understanding their potential complications is crucial for effective evaluation and review.
Article Synopsis
- Scapholunate instability is the leading type of carpal instability and its assessment relies heavily on imaging techniques, particularly X-rays.
- The article aims to examine the pre-operative evaluation stages, various surgical repair and reconstruction methods for the scapholunate ligament, and the expected post-surgery imaging results.
- It also discusses the potential complications that may arise from these surgical interventions.
Article Synopsis
- Scapholunate instability is the most prevalent type of carpal instability and requires imaging for proper assessment and management.
- In advanced cases, termed scapholunate advanced collapse, significant degenerative changes in the wrist occur.
- The article discusses various surgical treatments for different stages of this condition, focusing on postoperative imaging results and potential complications related to each surgical approach.
Article Synopsis
- Burnout is a psychological syndrome characterized by emotional exhaustion, depersonalization, and feelings of inadequate personal accomplishment, often due to prolonged workplace stress, and this study aimed to assess its prevalence among musculoskeletal radiology fellows.
- A 24-item survey based on the Maslach Burnout Inventory was distributed to fellows from 82 programs, with responses indicating higher levels of burnout in areas such as depersonalization and personal accomplishment, especially among female fellows.
- The findings highlight the importance of addressing burnout early, given its severe consequences, and emphasize the need for targeted interventions to improve the work-life balance and support for fellows.
Article Synopsis
- Overhead-throwing athletes commonly experience specific shoulder and elbow injuries due to their repetitive motions.
- There is a lack of detailed information about these injuries in the radiology literature, despite their well-known pathophysiology and terminology in clinical contexts.
- This review aims to highlight key imaging features of these injuries to improve diagnosis and treatment strategies for radiologists working with these athletes.
Objective: Burnout is a job-related psychological syndrome with three aspects: emotional exhaustion, depersonalization, and perceived lack of personal accomplishment. Burnout is associated with deleterious effects on both workers and their work. When burnout affects physicians, their well-being, longevity, and care of patients are at risk.

- The carpal boss is a bony growth found on the back of the hand near the bases of the second or third metacarpals, but it's not precisely defined.
- Researchers examined 129 wrist CT scans to understand the anatomy of the dorsal second and third carpometacarpal joints in the general population.
- Results showed that 82.2% of wrists had a dorsal protuberance on the third metacarpal; some showed more complex structures, and 6.2% had associated arthritis, suggesting a possible source of pain.
Article Synopsis
- The wrist is prone to various instability patterns due to its complex structure and movements.
- The Mayo classification is the most widely used system for categorizing carpal instability, and it's essential to grasp its terms for effective communication and accurate image interpretation.
- Standard wrist X-rays are the primary imaging tool for diagnosing carpal instability, with stress radiographs and other imaging techniques providing additional insights.
Disappearing Acts: The Many Causes of Rapidly Destructive Arthritis.
Curr Probl Diagn Radiol
May 2017
Most of the destructive joint disease necessitating arthoplasty is the result of an insidious and protracted process that occurs over the course of many years. However, there are a variety of diseases that may result in a rapid progressive deterioration of a joint. We describe both the common and less common etiologies of rapidly destructive arthropathy that one should consider, with imaging examples, and present discriminative factors when present.
