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 investigate whether magnetic resonance imaging (MRI) radiographers are able to evaluate MRI examinations with regard to scaphoid fractures to save patients unnecessary immobilization and clinical and radiographic examinations, and to reduce the costs for the hospital as well as society in general. ⋯ It is possible to provide an acute MRI service to patients with clinically suspected fracture of the scaphoid and a normal plain radiograph. The MR images can be primarily read by sufficiently trained MR radiographers. This new work-up protocol reduces the cost for society.

To develop a method to provide absolute values of regional myocardial perfusion by means of color maps, and to determine myocardial perfusion reserve using magnetic resonance imaging during the first pass of gadolinium-diethylenetriamine pentaacetic acid (Gd-DTPA). ⋯ Our new technique can provide absolute values of regional myocardial perfusion by means of color maps, and has potential for widespread use for evaluation of ischemic and other types of heart disease.

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.
