The presence of Fluid-Attenuated Inversion Recovery vascular hyperintensity (FVH) is able to discriminate symptomatic patients from asymptomatic patients in intracranial internal carotid artery or middle cerebral artery occlusion.
Figure 4 represents subgroup comparisons of the proportion of absence of FVH between symptomatic occlusion and asymptomatic occlusion. TIA: transit ischemic attack.
Figure 1 represents insular and M1-M6 regions for Fluid-Attenuated Inversion Recovery vascular hyperintensity Alberta Stroke Program Early Computed Tomography Score (FVH-ASPECTS) assessment. The illustrative case is scored as 3.
