Abstract

In recent years, the clinical impact has emphasized the need for a more detailed analysis of atherosclerotic plaques in carotid artery stenosis. Information beyond the resulting degree of narrowing of the vessel lumen on angiography seems to be desirable. Epidemiologic studies have shown that a large proportion of persons who have sudden ischemic events have no prior ischemic symptoms [43]. More importantly, it has been found that acute coronary syndromes often result from plaque rupture at sites with no or only modest luminal narrowing on angiography [64]; similar observations can be found in the coronary system [26]. Vascular remodelling has often occurred at such sites, which consists of atherosclerosis-associated morphologic and biologic changes of the vessel wall without significant stenosis [27]. Thus there is considerable demand for diagnostic procedures that specifically identify rupture-prone, vulnerable plaques as the most frequent cause of sudden ischemic events [44], [45], also in the cerebrovascular system.
