Meta AnalysisJOURNAL CLUB: Extracolonic Findings at CT Colonography: Systematic Review and Meta-Analysis.
The purpose of this study was to perform a systematic review and meta-analysis of published studies on CT colonography (CTC) in which extracolonic findings were assessed. ⋯ With use of the more robust C-RADS classification, potentially important extracolonic findings at CTC occur in less than 3% of cohorts without symptoms. For all extracolonic findings, the rate of suggested or recommended additional workup is approximately 8% but decreases to 4% for potentially important extracolonic findings.

Comparative StudyPerformance Comparison Between 18F-FDG PET/CT Plus Brain MRI and Conventional Staging Plus Brain MRI in Staging of Small Cell Lung Carcinoma.
The purpose of this study was to prospectively compare the capabilities of integrated FDG PET/CT and conventional staging for identification of TNM factors, evaluation of the TNM and Veterans Administration Lung Study Group (VALSG) stages, and selection of patients with stage I small cell lung carcinoma (SCLC). ⋯ Integrated FDG PET/CT with contrast-enhanced brain MRI is potentially equal to or more effective than conventional staging plus enhanced brain MRI for T, N, and M assessment and TNM and VALSG staging of SCLC.

Interval Change in Diffusion and Perfusion MRI Parameters for the Assessment of Pseudoprogression in Cerebral Metastases Treated With Stereotactic Radiation.
Apparent increases in the size of cerebral metastases after stereotactic radiosurgery (SRS) can be caused by pseudoprogression or true disease progression, which poses a diagnostic challenge at conventional MRI. The purpose of this study was to assess whether interval change in DWI and perfusion MRI parameters can differentiate pseudoprogression from progressive disease after treatment with SRS. ⋯ Pseudoprogression can be distinguished from disease progression in cerebral metastases treated with SRS via an interval decrease in relative CBV and Ktrans values.

A Women in Radiology Group Fosters Career Development for Faculty and Trainees.
The objective of our study was to evaluate the outcomes of a women in radiology (WIR) group during the first 6 years of its existence, including members' satisfaction, activities, and differences based on seniority. ⋯ A WIR group can provide career development tools for its members. In this study, trainees and junior faculty reported increased networking and research involvement and gaining a mentor but were equally likely as senior faculty to have become mentors. Most members reported increased camaraderie among women in the department. A WIR group may help to accelerate professional development among trainees and junior faculty, thereby contributing to a more diverse and enabled workforce.

Multicenter StudyTomosynthesis Impact on Breast Cancer Screening in Patients Younger Than 50 Years Old.
The question of benefits versus harms of breast cancer screening for women younger than 50 years old has been the subject of debate. We investigate if the addition of tomosynthesis to mammography improves screening performance outcomes for women in this age group. ⋯ Tomosynthesis in a community setting resulted in decreased recall rates for patients younger than 50 years old. For the subgroup of women with dense breast tissue, cancer detection rates also increased.
