Proximal end of dissection: Axial T1-weighted fat-saturated image through the upper neck demonstrates dissection of the left cervical internal carotid artery, with narrowing of the flow-related signal void starting at 4 cm from the ICA origin. Again seen is a crescentic hyperintense rim (red arrow) surrounding the narrowed flow-related signal void of the cervical ICA, likely representing subacute hemorrhage within the false lumen. The normal right ICA is visualized (blue arrow).
