Gender Disparity Among Leaders of Canadian Academic Radiology Departments.
OBJECTIVE. Underrepresentation of women in the top hierarchy of academic medicine exists despite women comprising more than half of the medical school graduates and residency positions. The purpose of this study is to analyze and quantify the relationship of gender, research productivity, and career advancement in Canadian academic radiology departments. ⋯ CONCLUSION. Canadian academic radiology departments have fewer women radiologists in senior faculty and leadership positions. Our study results show that Canadian female radiologists at the professor level have more publications than their male counterparts.

Comparative StudyComparison of 2D Shear Wave Elastography, Transient Elastography, and MR Elastography for the Diagnosis of Fibrosis in Patients With Nonalcoholic Fatty Liver Disease.
OBJECTIVE. The aim of the present study was to compare the diagnostic accuracy of liver stiffness measurements (LSMs) obtained using MR elastography (MRE), transient elastography (TE), and 2D shear wave elastography (SWE) in patients with biopsy-proven nonalcoholic fatty liver disease (NAFLD). SUBJECTS AND METHODS. ⋯ Pairwise comparisons revealed similar diagnostic accuracy for significant fibrosis (2D SWE vs MRE, p = 0.431; 2D SWE vs TE, p = 0.317; and MRE vs TE, p = 0.052) and advanced fibrosis (2D SWE vs MRE, p = 0.348; 2D SWE vs TE, p = 0.293; and MRE vs TE, p = 0.059). CONCLUSION. For patients with biopsy-proven NAFLD, 2D SWE, MRE and TE exhibited comparable and very good to excellent diagnostic accuracy for advanced fibrosis and comparable but lower accuracy for significant fibrosis.

Clinical Practice Characteristics of Radiologists Based on American Board of Radiology Interventional Radiology Certification Status.
OBJECTIVE. The objective of this study was to assess clinical practice characteristics of radiologists on the basis of American Board of Radiology (ABR) interventional radiology (IR) certification status. MATERIALS AND METHODS. ⋯ Although radiologists maintaining IR certification have higher IR work effort than those whose IR certification has lapsed, they are heterogeneous with overall sizable noninvasive diagnostic imaging practices. Approximately one-quarter of radiologists with predominant IR practices have never obtained IR certification. Because current IR/DR maintenance of certification testing exclusively addresses IR practice, attention is warranted to ensure certification is relevant to all IR diplomates.

Transmural Bowel Necrosis From Acute Mesenteric Ischemia and Strangulated Small-Bowel Obstruction: Distinctive CT Features.
OBJECTIVE. The purpose of this study was to assess whether transmural bowel necrosis has distinct CT features based on the three main causes: occlusive acute mesenteric ischemia (AMI), nonocclusive AMI, and strangulated small-bowel obstruction (SBO). MATERIALS AND METHODS. ⋯ CONCLUSION. Transmural bowel necrosis has distinct CT findings according to its three main causes. Occlusive AMI is characterized by an absence of bowel wall enhancement and less mesenteric fat stranding, nonocclusive AMI by a high prevalence of pneumatosis intestinalis and portal venous gas, and strangulated SBO by spontaneous hyperattenuation of the bowel wall and an absence of pneumatosis intestinalis and portal venous gas.
