Abstract

Rationale and Objectives. The competency of medical students in radiology clerkships is traditionally evaluated with film images, projected slides ofphotographed films, or printed reproductions of films. As radiology departments switch to filmless imaging, it seemed appropriate to determine the feasibility of an electronic evaluation prepared directly from digital images. Materials and Methods. The image-based portion of a multiple-choice final examination was prepared as a PowerPoint presentation that included images downloaded from the departmental picture archiving and communication system(PACS) or digital teaching collections. The images were downloaded as bitmap files, imported to Adobe Photoshop for image editing, converted to tagged image file format, and finally imported to PowerPoint, where they were combined with text to create 50 questions. A liquid crystal diode projector displayed the questions, with a timer set to advance them automatically. Results. The examination was easy and inexpensive to prepare (no photography costs). In an initial survey of 25 students, 17 (71%) of 24 students rated the resolution of images as excellent and five (21%) as good. No studentgave an image a poor rating. Students preferred that images cover at least40%-50% of the slides, and most approved of a blue background. An originalallowance of 30 seconds per slide was reported to be too fast; the interval was increased to 45 seconds. Conclusion. An electronic final examination for medical students, preparedwith images downloaded from PACS or digital teaching collections. is feasible, easy to prepare, and cost-effective, and it provides an excellent display of test images.
