While at this time there are more questions than answers, the recognition of an epidemiologic association between the administration of gadolinium-based MR contrast agents and the development of nephrogenic systemic fibrosis prompts caution in the use of these agents in the setting of renal disease.

Contrast-enhanced MR imaging is highly sensitive (94%) for detection of breast cancer in multimodality yearly surveillance—which also includes clinical breast examination, mammography, and US—in high-risk women; moreover, the positive predictive value of contrast-enhanced MR imaging (63%) is close to that of US (65%).

Rebecca S. Lewis, Mythreyi Bhargavan, and Jonathan H. Sunshine

Women and men radiologists differ in important professional respects and, thus, even if the percentage of posttraining, professionally active radiologists who are women does not increase beyond the approximately 25% we anticipate, the increase to 25% (from approximately 18% currently) is likely to have beneficial effects on some specialty-specific shortage and quality problems.

The findings of this study are that ventricular septal bowing, as detected at CT, had a low sensitivity for predicting death due to pulmonary embolism (PE) and a high degree of interobserver variability ({kappa} = 0.54), and that neither the ratio between the diameter of right ventricle and left ventricle nor embolic burden was associated with death due to PE.
