Topography of the hyperintense vessel sign on fluid-attenuated inversion recovery represents cerebral hemodynamics in middle cerebral artery occlusion: a CT perfusion study

Whether the topography of fluid-attenuated inversion recovery hyperintense vessel sign (FHVs) can serve as a measure of cerebral hemodynamic stress remains unclear. We hypothesized that FHVs topography represents different cerebral hemodynamic status, as assessed by CT perfusion (CTP). We retrospectively reviewed 75 patients with acute middle cerebral artery (MCA) occlusion who underwent MR imaging and CTP. The FHVs topography included FHVs...
