Research Abstract

In 30 of the 37 patients with misery perfusion detected by ^<15>O PET, susceptibility-weighted MR imaging demonstrated prominently hypointense signal within the superficial and deep cerebral veins ipsilaterally in steno-occlusive lesions. None of the 24 patients without misery perfusion detected by ^<15>O PET showed prominently hypointense signal within the cerebral veins. Susceptibility-weighted imaging was superior to GRE-EPI for visualization of the prominently hypointense cerebral veins with increased deoxyhemoglobin concentration. Our results suggest that susceptibility-weighted imaging is helpful in identifying misery perfusion in chronic cerebrovascular disease.
On GRE-EPI, engorgement of superficial and deep cerebral veins was frequently seen ipsilaterally in evolving infarction due to acute embolic occlusion.
