1 From the Biomedical Imaging Laboratory, Agency for Science Technology and Research, Singapore (G.L.Y., A. Aziz, B.N., A. Anand, W.L.N.); and National Neuroscience Institute, Singapore (C.C.T.L.). Presented as an infoRAD exhibit at the 2004 RSNA Annual Meeting. Received March 23, 2005; revision requested May 25 and received July 11; accepted July 18. Supported by the National Healthcare Group and the Biomedical Research Council of the Agency for Science, Technology and Research, Singapore. All authors have no financial relationships to disclose. Address correspondence to G.L.Y., 30 Biopolis St, 07-01 Matrix, Singapore 138671 (e-mail: glyang{at}sbic.a-star.edu.sg).

A new method has been developed for multimedia enhancement of electronic teaching files created by using the standard protocols and formats offered by the Medical Imaging Resource Center (MIRC) project of the Radiological Society of North America. The typical MIRC electronic teaching file consists of static pages only; with the new method, audio and visual content may be added to the MIRC electronic teaching file so that the entire image interpretation process can be recorded for teaching purposes. With an efficient system for encoding the audiovisual record of on-screen manipulation of radiologic images, the multimedia teaching files generated are small enough to be transmitted via the Internet with acceptable resolution. Students may respond with the addition of new audio and visual content and thereby participate in a discussion about a particular case. MIRC electronic teaching files with multimedia enhancement have the potential to augment the effectiveness of diagnostic radiology teaching.
