[Abstract] The fluid-attenuated inversion recovery vascular hyperintensity (FVH) is a common sign of MR imaging, which is tubular or serpentine hyperintensities in the subarachnoid space relative to cerebrospinal fluid. In addition to cerebrovascular diseases, there are other causes that can lead to the appearance of FVH, and FVH also has a specific location. The formation mechanism of FVH is complex, and it is mainly thought that FVHs are related to hemodynamic impairment and represent slow retrograde flow in leptomeningeal collaterals. The emergence of FVH is of great clinical significance, it can be used to evaluate cerebral artery stenosis and cerebral infarction, collateral circulation and ischemic penumbra. In addition, FVH sign plays an important role in the evaluation of vascular recanalization, prognosis and outcome. Therefore, comprehensive and complete evaluation of FVH sign is of great significance for the treatment decision and prognosis of patients with acute ischemic stroke. This article reviewed the definition, mechanism, clinical application and prospect of FVH.
