MRA findings in ulcerated carotid plaques. Axial T2-weighted image (a) showing flow void in the vessel lumen and slightly higher signal intensity within the origin of internal carotid artery, possibly representing a stenotic plaque (arrowhead). Contrast-enhanced MRA (b) identifying a type 3 ulcerated carotid plaque (arrowhead, same patient with Fig. 4d ). Axial T2-weighted image (c) showing a projection of the luminal flow void within a high-signal intensity area, consistent with an ulcerated fatty plaque (arrowhead). Contrast-enhanced MRA (d) confirming the presence of a type 1a ulceration (arrowhead, same patient as in Fig. 4a ). Axial contrast-enhanced T1-weighted image confirming the presence of contrast material within the ulcer’s cavity (arrow) (e)
