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.
