The correlation of fluid-attenuated inversion recovery imaging (FLAIR) vascular hyperintensity (FVH) and collateral are still in discrepancy in intracranial atherosclerotic stenosis or occlusion. In the present study, we used territorial arterial spin labeling (ASL) and two post labeling delay (1.5s and 2.5s) ASL to study the leptomeningeal collateral and hemodynamic status in patients with different intensity of FVH, and concluded that FVH may be related to poor collateralization and hemodynamic impairments.
