Intracranial artery steno-occlusive disease causes high morbidity of ischemic stroke occurrence and reoccurrence. The present study tested the presence of Fluid-Attenuated Inversion Recovery vascular hyperintensity (FVH) to discriminate symptomatic patients from asymptomatic patients in intracranial internal carotid artery or middle cerebral artery occlusion and found that the presence of FVH was independently associated with a recent ischemic event in these patients and negatively correlated with collateral circulation. The findings suggest that FVH may serve as a feasible imaging marker to identify high-risk cases in their follow-up and clinical management.
