Abstract

While reviewing the past year in diagnostic radiology, I was reminded of many important developments that have the potential to improve patient care. As Contempo authors are asked to restrict their discussions to only "key" advances likely to be of interest to readers in other specialties, I limit this review to four areas: magnetic resonance imaging (MRI), sonography, interventional radiology, and economic issues in diagnostic radiology.

Magnetic resonance imaging continues to develop in multiple directions. Perhaps most exciting was a report that MRI can actually identify and map the areas of the human brain that are active during a variety of neurological functions.1 If this is verified, MRI becomes a competitor to positron emission tomography as an imaging technique for identifying and analyzing higher brain function. Positron emission tomography technology is mature and well developed, and its ability to identify regions important to brain function is especially valuable. With
