Figure 4: VWI of Symptomatic ICAS with T2 Hyperintensity and Enhancement.

Figure 4:

(A) A patient with acute infarction in the left centrum semiovale showed (B) severe flow-limiting stenosis in the left supraclinoid internal carotid artery on 3D TOF MRA (arrowhead). (C) Cerebral angiogram showed trace flow through this severely stenotic segment (arrowhead). (D) At the site of stenosis, sagittal T2w VWI showed eccentric T2 hyperintense signal (arrowhead). (E) Precontrast T1w VWI and (F) postcontrast T1w VWI reveals plaque enhancement (arrowhead).
