Ultrasound contrast is rapidly becoming an integral part of echocardiography, the technique most widely used to image the heart. This book is the result of the authors' combined experience in research into the agents and their associated imaging techniques and in clinical application of contrast echocardiography over a period of ten years. Its aim is to provide the clinical echocardiographer with a complete guide and reference for performing and interpreting a contrast echo study. The copious illustrations accompanying the text are supplemented by the generous contributions of more than a dozen worldwide authorities who have provided cases that convincingly demonstrate the general applicability of this new technology.
