Randomized Controlled Trial Comparative Study Clinical Trial
Tutor versus computer: a prospective comparison of interactive tutorial and computer-assisted instruction in radiology education.
This study compared the educational effectiveness of an interactive tutorial with that of interactive computer-assisted instruction (CAI) and determined the effects of personal preference, learning style, and level of training. ⋯ Interactive tutorial and optimal CAI are both effective instructional formats. The tutorial was marginally but significantly more effective at teaching factual knowledge, an effect unrelated to students' year of training, learning style, or stated enjoyment of CAI. The superiority of the tutorial is expected to increase when it is compared with commercially expedient CAI modules.

The purpose of this study was to determine the range of findings at diffusion-weighted magnetic resonance (MR) imaging in patients with systemic lupus erythematosus (SLE) and central nervous system involvement. ⋯ Diffusion-weighted imaging shows primarily two patterns of acute or subacute parenchymal lesions in patients with SLE: acute or subacute infarction and vasogenic edema with or without microinfarcts.

The purpose of this study was to determine if annual total work relative value units (RVUs) can be used to accurately compare physician productivity and effort among a small group of similarly trained radiologists. ⋯ The RVU is an accurate measure of income production but may be an inaccurate measure of effort and individual productivity because of differences in duty assignments. In a relatively homogeneous group of radiologists/practitioners, such a comparison should be done within a duty service, or a correcting methodology should be used, because assignment to duty services rarely is equalized across physicians.

The authors tested whether noninvasive magnetic resonance (MR) oximetry is accurate in the in vivo measurement of oxygen saturation in a stroma-free, hemoglobin-based oxygen carrier (HBOC). ⋯ Noninvasive in vivo MR measurement of oxygen saturation is valid for whole blood mixed with stroma-free hemoglobin. Therefore, MR oximetry may be clinically useful for assessing the oxygenation status in patients resuscitated with a HBOC.

The purpose of this project was to understand better the academic radiologist's clinical workload in order to determine faculty staffing requirements more accurately. ⋯ The SCARD survey provided very useful clinical workload data, measured in work RVUs per FTE for specific subspecialty sections. At practically all surveyed institutions, increasing clinical workload is competing with academic activities.
