This book reflects the views of an international faculty and provides an authoritative appraisal of modern radiology. It represents the sec ond volume in a planned series of competent overviews, and is mod eled on the successful first volume, Radiology Today, which was enthu siastically received by an international readership. We were encour aged by the comments we received to continue blending the latest ad vances in radiology with comprehensive teaching material concerning modern radiological practice. The Radiology Today 1982 meeting again brought together outstanding radiologists from Europe and North America for the purpose of sharing their experiences and their viewpoints of the current position and opportunities of imaging in medicine. Updating his/her knowledge of advances in medical imaging has be come an integral part of continuing medical education for every radiol ogist. Because all imaging modalities are continuously being refined, new clinical applications develop and frequently replace more com plex or more invasive procedures. Also, the relationship of imaging procedures to each other changes constantly, and with it the configura tion of critical diagnostic pathways for investigation of clinical signs and symptoms. To recognize this trend is important, because it is ex panding the role of the radiologist: our involvement in active guidance to the point of the patient's diagnostic workup has increased signifi cantly where it has become strategic."

This book encompasses the proceedings of a very successful post graduate course entitled "Radiology Today" held in Salzburg in June 1980. It was organised by Dr. Martin W. Donner of Baltimore and Dr. F. H. W. Heuck of Stuttgart. It was attended by 230 radiologists from 17 countries. The aim was to select a certain number of subjects in diagnostic radiology and in each to have a broad spectrum overview reviewing recent advances presented by an acknowledged expert, followed by a series of rather more detailed papers on various aspects of that field, again given by acknowledged experts drawn from countries throughout Europe and also from the United States of America. This series of presentations on a theme was then followed later the same day by a "workshop" discussion at which the speakers, sometimes joined by other experts from collateral fields of interest, acted as a panel for discussion with the over-view speaker acting as moderator.

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.

The biennial symposium 'Radiology Today' continues its original mission to bring together European and American radiologists to discuss advances in the field. This volume presents material by well-known experts in cardiovascular and skeletal radiology. Its aim is to provide an overview of each major topic, trends in clinical development, and current interests in research. The future holds much promise for cardiovascular and skeletal radiology, primarily because of new techniques and procedures, but also because of the development of imaginative approaches to clinical problems. Ideas are born on both sides of the Atlantic, and we believe that it is important to ensure a rapid exchange of new information and to determine how it fits into today's medical care, keeping in mind the quality of patients' care, their safety and comfort, as well as cost. The traditional role of radiologists as consultants has increased greatly over time, with new responsibilities being continuously added. We radiologists are challenged to determine the diagnostic pathway appropriate to each patient. To arrive at the diagnosis quickly, safely, and at the lowest possible cost is as important as our participation in determining the patient's management. Some therapeutic procedures are even carried out by diagnostic radiol ogists themselves, employing ultrasound, computed tomography, or fluoroscopy and intracavitary catheters. Abscesses can be drained, and blood vessels dilated or blocked. In diagnosis and therapy, events are moving quickly, and advances are made at a rapid pace."

In diesem Band werden "alle" Teile des Gastrointestinaltraktes durch international anerkannte Spezialisten behandelt und alle modernen bildgebenden Verfahren erfasst. Neben dem Schwerpunkt der konventionellen Rontgendiagnostik werden die neuen bildgebenden Verfahren wie Ultraschall, Computer- und Kernspintomographie einbezogen. Besonderer Wert wurde auf das Doppelkontrastverfahren des gesamten Gastrointestinaltraktes gelegt. Auch die Belange der modernen Endoskopie, sowie Besonderheiten im Kindesalter werden gewertet. Das hervorragende Bildmaterial erleichtert die Nutzung der Informationen fur die tagliche Arbeit der Internisten und Radiologen der Fachgebiete."
