FLAIR vascular hyperintensity is associated with cerebral edema in anterior circulation stroke.
OBJECTIVE T2 Fluid-attenuated Inversion Recovery (FLAIR) vascular hyperintensity (FVH) refers to a slow blood flow through the leptomeningeal collaterals. Whether FVH relates to cerebral edema in acute ischemic stroke (AIS) remains unclear. We aimed to i) explore the association between FVH and cerebral edema in patien...
