Uterine artery embolization (UAE) is an effective treatment for the management of symptomatic uterine fibroids. We aim to evaluate the efficacy of superior hypogastric nerve block (SHNB) in reducing narcotic analgesia use for postprocedural pain after UAE. ⋯ The use of SHNB could significantly reduce the amount of narcotic analgesia required for pain control after UAE with larger intramural fibroids and younger patients as predictors of increased efficacy.

To determine burnout prevalence in Canadian radiology residency and identify contributing factors. ⋯ This study demonstrates significant burnout in Canadian radiology residents with major contributory factors identified.

Fournier gangrene (FG) is a genitourinary necrotizing fasciitis that can be lethal if not promptly diagnosed and surgically debrided. The diagnosis is often made by physical examination paired with an appropriate clinical suspicion and supporting laboratory values. Imaging, particularly computed tomography (CT), plays a role in delineating involved fascial planes for operative debridement and occasionally in diagnosing FG. ⋯ Women with FG are more likely to be morbidly obese and have vulvar or labial involvement compared to men. Imaging mimics include ulcerative and necrotic tumors, traumatic or iatrogenic fascial gas, and vaginitis emphysematosa. The purpose of this pictorial review is to illustrate the imaging manifestations of FG and its mimics, with emphases on necrotizing fasciitis CT scoring systems and FG in women.

Observational Study
A Single-Institute Experience With Radioactive Seed Localization of Breast Lesions-A Retrospective Study.
To assess the benefits associated with radioactive seed localization (RSL) in comparison to conventional wire localization (WL) for nonpalpable breast lesions. ⋯ The use of RSL, as compared to conventional WL, resulted in a reduction in the number of pathologically involved surgical margins and was associated with an increased number of surgeries. Furthermore, RSL can be performed up to 14 days prior to surgery, which may improve scheduling flexibility in the radiology department.

To evaluate the efficacy of the semiquantitative and quantitative parameters of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) in differentiating between benign and malignant soft-tissue tumors. ⋯ The use of semiquantitative and quantitative parameters of DCE-MRI enabled differentiation between benign and malignant soft-tissue tumors. The values of TTP were lower, while those of MAX Conc, AUC-TC, MAX Slope, Ktrans, and Kep were higher in malignant than in benign tumors.
