Hyperintense Vessel Sign on High-Resolution Vessel Wall MRI and Perfusion Decompensation in Intracranial Atherosclerotic Disease: Burden Versus Proximal Extent.
RATIONALE AND OBJECTIVES To investigate the relationship between hyperintense vessel sign (HVS) on high-resolution magnetic resonance vessel wall imaging (HR-VWI) and cerebral perfusion decompensation in patients with intracranial atherosclerotic stenosis or occlusion. MATERIALS AND METHODS This retrospective cohort...
