Non-Invasive Imaging of Atherosclerosis is a primer, reference and review of some of the key features of current activities in the field of atherosclerosis. The Editors' goal is to provide material and stimulating ideas to basic scientists and clinical researchers in order to extend the application of vascular imaging and to further develop methods suitable for investigation of the arterial wall. The first section presents current knowledge about pathology, vascular mechanics and compensatory mechanisms active during atherogenesis. It explores the early lesion, complications of plaques and early detection of plaques. Section II reviews several key methodological issues of B-mode ultrasound imaging and some of the most current data. Quantitative B-mode ultrasound is an established non-invasive tool widely used in large epidemiologic studies and interventional clinical trials of atherosclerosis. The last section addresses the most promising areas of development in vascular imaging. This involves new techniques to evaluate the atherosclerotic bed, to follow atheroma progression/regression and to evaluate vascular mechanics in atherosclerotic arteries. The last chapter places the application of non-invasive imaging in perspective.
