Views of radiology program directors on the role of mentorship in the training of radiology residents.
The successful mentoring of resident physicians has been linked to several beneficial outcomes for trainees including increased research productivity, improved career satisfaction, and retention in academics. Female residents may have greater difficulty establishing mentoring relationships than male residents. The purpose of this study was to assess the attitudes of radiology residency program directors toward the subject of mentorship, to determine the prevalence of formal mentoring programs, and to evaluate several issues specifically pertaining to the mentoring of female residents. ⋯ Program directors consider mentoring relationships to be an important resource for resident professional development and a potential resource to increase the proportion of residents pursuing academic careers and positions of leadership. Female residents may have specific mentoring needs that should be explored with further study.

Liver MRI at 3 T using a respiratory-triggered time-efficient 3D T2-weighted technique: impact on artifacts and image quality.
The purpose of this retrospective study was to qualitatively and quantitatively compare image quality of a time-efficient 3D T2-weighted sequence-the sampling perfection with application-optimized contrasts using different flip angle evolutions (SPACE) sequence-with a standard 2D T2-weighted turbo spin-echo (TSE) sequence for liver imaging at 3 T. ⋯ For T2-weighted liver imaging at 3 T, the respiratory-triggered SPACE sequence shows better image quality with near elimination of motion and pulsation artifacts and improved tissue contrast than the breath-hold 2D TSE sequence, but suffers from increased B(1) inhomogeneity artifact and longer scanning time.

Multicenter StudyRadiofrequency ablation for the treatment of bone metastases from hepatocellular carcinoma.
The objective of our study was to retrospectively evaluate the clinical utility of bone radiofrequency ablation in patients with bone metastases from hepatocellular carcinoma (HCC). ⋯ Bone radiofrequency ablation is a safe, useful, and feasible therapeutic option for relieving pain in patients with HCC bone metastases. Prognostic factors reported herein can facilitate stratification of patients with HCC bone metastases.

Percutaneous abscess drainage in patients with perforated acute appendicitis: effectiveness, safety, and prediction of outcome.
The purposes of this study were to retrospectively investigate the effectiveness and safety of CT-guided percutaneous drainage in the treatment of patients with acute appendicitis complicated by perforation and to identify CT findings and procedure-related factors predictive of clinical and procedure outcome. ⋯ CT-guided percutaneous drainage is both effective and safe in the treatment of patients with acute appendicitis complicated by perforation and abscess. The clinical and technical success rates are high.
