Figure 1 (A) A small eccentric plaque within the carotid thought to be composed of fibrous tissue (FT) (dark in time of flight [TOF], moderate/high in both T1- and proton density (PD)-weighted images) indicates a type III plaque. (B) A carotid plaque consisting of both lipid and fibrous tissue, with a region of calcium deposits (Ca) indicative of a type IV to V plaque. (C) A carotid lesion with recent intraplaque hemorrhage (arrows) demonstrating high signal intensity on all sequences, and no evidence of plaque rupture with a thick fibrous cap surrounding the lumen (arrowhead). Figure 1C reproduced, with permission, from Kampschulte et al. (12).
