Tales of Mentoring in Radiology: The Experience of Residents and Mentors at a Single Academic Program.

PURPOSE: To investigate the utility of mentoring groups in radiology residency. METHODS: Five assistant professors of Radiology and 20 radiology residents were divided into 5 groups. One resident from each academic year was randomly paired with a mentor group. Three 1-hour group mentoring sessions took place over the year. Upon completion of the project an anonymous Quality Improvement survey of 20 questions were sent out to participants to assess the utility of these mentoring sessions. RESULTS: Four mentors out of 5 responded. All 4 had prior neutral and positive experiences as mentees involving career advice and subspecialty choice. During this experience all mentors had a positive experience. The majority found it helpful to have residents of different levels in their group to allow for peer to peer mentoring and all thought the mentoring program should continue. The most common topics they covered during the sessions were career advice and specialty choice. Sixteen residents out of 20 responded. The majority had had a previous mentor experience which was mostly positive or very positive and predominantly career and/or research related. Almost all of them had a positive or very positive mentoring experience this year. The high majority found that having residents of different levels was beneficial. Topics that mentoring sessions helped mostly with were career advice, work life balance and study skills. All of the mentees thought the mentoring program should continue. CONCLUSIONS: Mentoring groups can be a valuable addition to residency training, especially in helping with career advice and work life balance.

Median Arcuate Ligament Syndrome: A Single-Center Experience with 23 Patients.

BACKGROUND: Median arcuate ligament syndrome (MALS) is a rare entity that occurs when the median arcuate ligament of the diaphragm is low-lying, causing a compression to the underlying celiac trunk. We reviewed the vascular changes associated with MALS in an effort to emphasize the seriousness of this disease and the complications that may result. METHODS: This is a retrospective descriptive analysis of 23 consecutive patients diagnosed with MALS between January 1, 2012 and December 31, 2015 at a tertiary medical center. Computed tomographic (CT) scans, medical records, and patient follow-up were reviewed. RESULTS: The number of patients included herein was 23. The median age was 56 years (17-83). Sixteen patients (69.6%) had a significant arterial collateral circulation. Eleven patients (47.8%) were found to have visceral artery aneurysms; 4 patients (36.4%) bled secondary to aneurysm rupture. All ruptured aneurysms were treated with endovascular approach. The severity of the hemodynamic changes appears to be greater with complete occlusion, CONCLUSIONS: MALS causes pathological hemodynamic changes within the abdominal vasculature. Follow-up is advised for patients who develop a collateral circulation. Resulting aneurysms should preferably be treated when the size ratio approaches three. Treatment of these aneurysms can be done via an endovascular approach coupled with possible celiac artery decompression to restore physiologic blood flow.

Cortical bone invasion in non-transfusion-dependent thalassemia: tumefactive extramedullary hematopoiesis reviewed.

OBJECTIVE OF THE STUDY: To assess the prevalence of cortical bone invasion (CBI) with secondary extramedullary hematopoiesis (EMH) in patients with non-transfusion-dependent thalassemia (NTDT), to determine its predilection sites on thoracic and abdominal imaging, to determine whether there is an association between various clinical and hematological parameters, and to evaluate its various findings mainly on magnetic resonance imaging (MRI), in addition to computed tomography (CT) scans. MATERIALS AND METHODS: This is a retrospective cohort study of 57 patients with NTDT imaged by CT or MRI. Both clinical and laboratory data were gathered. An imaging scoring system was used to describe the appearance of CBI by MRI. RESULTS: Twenty-seven patients (47.4 %) were found to have CBI and EMH with the most common location being the thoracic spine. Splenectomy and lower hemoglobin level were found to be independent risk factors for its development. Most lesions were homogenous (70 %), had predominant red marrow signal (67 %), and well-defined margins (89 %). CONCLUSION: CBI and secondary tumefactive EMH are common findings in patients with NTDT, with distinct imaging and clinical characteristics. An increased risk was seen in patients with splenectomy and lower hemoglobin. The imaging scoring system described is helpful in diagnosing and describing this entity, hence precluding unnecessary biopsies.
