Although a broad spectrum of entities can induce acute pathologic changes in the small bowel, there are relatively few imaging features that are characteristic of a specific diagnosis on the basis of CT findings. Specific clinical information, including time course and onset of disease, patient risk factors, and any recent pharmacologic or radiation therapy, is often instrumental in refining the differential diagnosis. A wide spectrum of disorders is reviewed in this article; however, given the breadth of disorders associated with the small bowel, neoplastic and infectious conditions affecting the small bowel that can manifest acutely are not specifically discussed. Vascular diseases that can affect the small bowel regionally or diffusely, including thromboembolic and hypoperfusion phenomena, as well as a spectrum of vasculitides, are reviewed. Iatrogenic causes of small bowel disorders are discussed, including angiotensin-converting enzyme inhibitor-induced angioedema, and chemotherapy- and radiation therapy-associated patterns of disease. Autoimmune and hereditary conditions that can affect the small bowel, including systemic lupus erythematosus and genetic C1 esterase inhibitor deficiency, respectively, are reviewed. ^©RSNA, 2018.

OBJECTIVE:Common fetal anomalies of the kidneys and urinary tract encompass a complex spectrum of abnormalities that can be detected prenatally by ultrasound. Common fetal anomalies of the kidneys and urinary tract can affect amniotic fluid volume production with the development of oligohydramnios or anhydramnios, resulting in fetal pulmonary hypoplasia and, potentially, abnormal development of other fetal structures. CONCLUSION/CONCLUSIONS:We provide an overview of common fetal anomalies of the kidneys and urinary tract with an emphasis on sonographic patterns as well as pathologic and postnatal correlation, along with brief recommendations for postnatal management. Of note, we render an updated classification of fetal abnormalities of the kidneys and urinary tract based on the presence or absence of associated urinary tract dilation. In addition, we review the 2014 classification of urinary tract dilation based on the Linthicum multidisciplinary consensus panel.

PURPOSE/OBJECTIVE:To examine trends in female authorship in the journal Emergency Radiology from January 1994 to December 2014. METHODS:We obtained institutional review board approval for our study. We retrospectively reviewed a total of 1617 articles published in the journal Emergency Radiology over a 20-year period. Original articles, case reports, review articles, and pictorial essays were included. The first and last position author's gender was categorized as female or male. We analyzed trends by comparing the first and last position authors of original articles from the first and last year reviewed. We utilized Chi-square test for statistical analysis, with a p value <0.05 noted as significant. RESULTS:One thousand four hundred twenty articles met our inclusion criteria. There were 1420 first position authors and 1295 last position authors. There were 125 articles that had a sole author-these authors were considered as first position authors only. We determined, as best as possible, the gender of 96% of the authors. Overall, female authors were 21% of first position authors (290 of 1368) and 15% of last position authors (183 of 1246). Thirty-two percent of articles with female last position authors also had female first position authors (58 of 183). There was a statistically significant increase in female last position authors, from 12.9% in 1994 to 21.3% in 2014 (p = 0.026), a non-significant increase in female first position authors, from 17.5% in 1994 to 20.9% in 2014 (p = 0.514), and a non-significant increase in articles with both a first and last female author, from 25% in 1994 to 35% in 2014 (p = 0.593). CONCLUSION/CONCLUSIONS:Over the last 20 years, there has been a statistically significant upward trend in female last position authors publishing in the journal Emergency Radiology.

We highlight what we believe are 2 major areas of weakness in current Canadian radiology training programs: insufficient community radiology training and limited preparation of residents for the job market. Although focusing on Canadian radiology programs, we suspect that these are also 2 areas of substantial concern for radiology training programs in the United States and other countries. We offer suggestions to address these deficiencies, particularly by using pre-existing hybrid radiology practices and by making relatively small changes to the current curricula of radiology residency programs.

Mentoring is an extremely important component of academic medicine, including radiology, yet it is not specifically emphasized in radiology training, and many academic radiology departments in the United States, Canada, and elsewhere do not have formal mentoring programs for medical students, residents, fellows, or junior faculty. The purpose of this article is to overview the current status of mentorship in radiology, to discuss the importance of mentorship at multiple levels and its potential benefits in particular, as well as how to conduct a successful mentor-mentee relationship. The literature on mentorship in radiology and in academic medicine in general is reviewed.

The failure to diagnose acute appendicitis (AA) is the third most common medical malpractice allegation related to gastrointestinal disease. There is a paucity of detailed data on this topic; however, publications by Whang et al and by Berlin and Berlin, which analyzed all types of malpractice suits against radiologists, have shown that the incidence of litigation has increased over time in the United States. This is likely true for cases of AA as well. The misinterpretation of cross-sectional imaging in patients with suspected appendicitis may be caused by suboptimal technique, errors of omission, i.e, missing key findings, failure to review a portion of the examination, and satisfaction of search error. This article summarizes the published legal, clinical, and imaging literature regarding litigation in cases of missed AA, and reviews optimized multidetector computed tomography and magnetic resonance imaging protocols for the diagnosis of AA, with examples shown of challenging cases.
