What’s New in Cardiovascular Imaging is a bibliographical "image" of a Symposium held June 22-24, 1998 in Leiden, the Netherlands. At this Symposium all the major advances in car- diovascular imaging in all the cardiovascular imaging modalities (X-ray, (intravascular) ultra- sound, magnetic resonance, scintigraphy and CT) were addressed by the leading authorities in this field. Based on the presentations of the invited Faculty, this book consists of a compi- lation of manuscripts related to most of the topics discussed at this particular meeting. We express our gratitude to all authors and coauthors for having made great efforts in preparing their superb up-to-date chapters under a great time pressure, so that this book was available at the time of the Symposium. The authors are all excellent investigators in one or more fields of cardiovascular imaging and they have stimulated progress in cardiovascular imaging with the aim to improve patient care and clinical research. This book consists of a total of 32 chapters subdivided into seven Parts. Each part describes a particular field in cardiovascular imaging. These Parts are: Coronary quantitation by QCA and intracoronary ultrasound (QCU), angiographic trials, progress in intravascular ultrasound, magnetic resonance (MR) coronary and vascular imaging, nuclear cardiovascular imaging, echocardiography, and cine and spiral CT coronary imaging. In general, each Part begins with a chapter that provides a broad overview of the advances in the field described in that particular Part, as well as a view towards the future.
