Fig 3. A 78-year-old man with TIA. Ulcerated plaque of the left CCA. Axial scan (A) shows ulcerations in a calcified plaque; the atheromatous plaque involved the common carotid artery, the carotid bifurcation, and internal carotid artery origin. This ulcer is proximal to the point of maximum stenosis (90% NASCET). The ulceration was easily detected using VR technique with 1 histogram (B) and 2 histograms (C, D). Ulceration was less clearly visible using MIP and MPR reconstruction (E, F). Note: B is an internal visual, where the lumen is cut to clarify the ulcers. (red arrow in axial image and yellow arrows in VR, MIP, and MPR images, ulceration; green arrows, ICA; blue arrows, CCA)
