Accurate quantification of the shape and extent of breast tumors has a vital role in nearly all applications of breast magnetic resonance (MR) imaging (MRI). Specifically, tumor segmentation is a key component in the computerized assessment of likelihood of malignancy. However, manual delineation of lesions in four-dimensional MR images is labor intensive and subject to interobserver and intraobserver variations. We developed a computerized lesion segmentation method that has the advantage of being automatic, efficient, and objective. ⋯ Our proposed algorithm for breast-lesion segmentation in dynamic contrast-enhanced MRI was shown to be effective and efficient.

Stratifying candidates objectively on the merit of publication portfolios is an onerous and difficult task. Institutional committees are under increasing pressure to rank applicants based on previous achievements for appointments/promotions, funding, and awards, and must do so within unforgiving time constraints. The journal impact factor (IF) has been loosely adopted in many circles for assessing article "quality," circumventing detailed review of individual articles. The premise supporting such practice often hinges on assuming that high-IF journals are harder to publish in, for example, have higher rejection rates (RRs), and therefore, authors achieving publication in such periodicals should be "recognized" for their achievement. There is no evidence of previous research linking IF and RR. ⋯ In summary, this study demonstrates poor linear agreement between IF and RR for manuscripts submitted to peer-reviewed radiology journals. This suggests that journal IF is a poor predictor of RR, and vice versa. This finding may be of interest to institutional committees who have adopted the IF as an indicator of merit in reviewing publication curriculum vitae, and may encourage rethinking of currently practiced candidate assessment approaches.

The aim of the study is to gauge radiology fellowship directors' experiences with the fellowship application process and perceptions of the National Resident Matching Program Radiology Fellowship Match, as well as compare these perceptions with those of senior residents. ⋯ Although there are significant differences in perception of the Match process between fellowship directors and senior residents, the majority of fellowship directors favor continuing the Match in some form. Several potential solutions, including explicit declaration of the number of available positions and strict enforcement of Match rules, may help improve the process in the future.
