Fluid-Attenuated Inversion Recovery Vascular Hyperintensities in Transient Ischemic Attack within the Anterior Circulation

Figure 3

FVH absent in a patient with left middle cerebral artery severe stenosis (M1). (a) MRA showed a severe stenosis of left MCA M1. (b) No hyperintense signal of the middle cerebral artery branch was found in the corresponding fissure or the sulci of the left fronto-parietal lobes. (c) CT perfusion imaging showed hypoperfusion with prolonged MTT in the bilateral anterior and posterior cortical border zones, and no clearly decreased CBF or CBV values were found.
