To develop and test the reliability, validity, and feasibility of a 360-degree evaluation to measure radiology resident competence in professionalism and interpersonal/communication skills. ⋯ Results from this pilot study suggest that self, faculty, and patient evaluations of resident performance constitutes a valid and reliable assessment of resident competence. Additional data are needed to determine whether the 360-degree assessment should be incorporated into residency programs and how frequently the assessment should be performed. Requiring only a specified number of assessments per rotation would make the process less burdensome for residents and faculty.

Case Reports Comparative Study
Computer-assisted diagnosis by temporal subtraction in postoperative brain tumor patients: a feasibility study.
To introduce and evaluate a novel, image fusion-based technique that can be used to compare the findings of primary and control brain magnetic resonance imaging scans, with special attention to the differences found in this comparison. ⋯ Colored difference mapping is suitable for comparison of images between two different radiologic examinations and helps to show even minimal changes in brain tissues.

To determine the in vivo feasibility of quantifying early degenerative changes in patellofemoral joint of symptomatic human knee using spin-lattice relaxation time in the rotating frame (T(1rho)) magnetic resonance imaging (MRI). ⋯ Preliminary results demonstrated the in vivo feasibility of quantifying early biochemical changes in symptomatic osteoarthritis subjects employing T(1rho)-weighted MRI on a 1.5 T clinical scanner. This study on limited number of symptomatic population shows that T(1rho)-weighted MRI provides a noninvasive marker for quantitation of early degenerative changes of cartilage in vivo. However, further studies are needed to correlate early osteoarthritis determined from arthroscopy with T(1rho) in a large symptomatic population.

We surveyed program directors to determine current radiology program practices in evaluating their residents, faculty, and program. ⋯ In general, there is a high degree of compliance among radiology programs in meeting ACGME evaluation requirements. However, some programs do not comply with requirements for frequency of resident evaluation or annual program evaluation. The percentage of new program directors is high and related to not using or knowing about useful evaluation resources. Use of computerized evaluation systems, which have the potential to decrease the work associated with evaluations and provide more dependable and reliable data, is minimal.

To compare conventional radiofrequency coil reception techniques with parallel coil array acquisition methods in adrenal tissue visualization and to evaluate the dependence of temporal resolution on image quality in adrenal magnetic resonance magnetic resonance (MR) imaging. ⋯ Parallel acceleration of sequences used for adrenal tissue visualization leads to a significant increase in diagnostic quality by significantly reducing breathing motion artifacts without sacrificing contrast indispensable for adrenal lesion characterization.
