Radiology Today 3 presents papers and panel discussions from a multi- national faculty at the biannual Salzburg Symposium, which this time covered three important topics: critical diagnostic pathways in gastro" intestinal and genitourinary radiology, interventional radiology of the abdomen, and cost containment in radiology. The choice of these topics illustrates the changing role of the radiolo- gist in the practice of medicine today and in the foreseeable future. He will have to serve as a consultant more than ever before, assuming in- creasing responsibility for sequencing of imaging procedures and par- ticipating more and more in therapeutic intervention. In order to pro- vide meaningful assistance, the imaging consultant must be aware of the efficacy and the limitations of every procedure. In this context, cost containment is a worldwide public concern, and the most appropriate procedures must be identified. Radiology Today 3 demonstrates how the radiologist functions as a member of diagnostic and management teams to provide optimal in- formation and efficient, low-risk patient care at the lowest possible cost.
