Gastroenterology is one of the branches of medicine that can profit most from modem technology, whether this involves the advances in diagnostic instrumentation, in data and image processing and management, or in computer applications like expert systems. To evaluate current status of imaging, computerization, and expert systems in gastroenterology, a group of clinical researchers and computer experts met in Bologna, Italy, for several days'' discussion. The presentations at this symposium are introduced in this volume, which we believe to be a useful contribution to a specialization of great importance for health care as a whole.
