MR perfusion imaging in Moyamoya Syndrome: potential implications for clinical evaluation of occlusive cerebrovascular disease.
BACKGROUND AND PURPOSE Ischemic symptoms in patients with moyamoya syndrome (MMS) are usually due to hemodynamically mediated perfusion failure, and identification of abnormal tissue perfusion in these patients is therefore clinically important. Although dynamic susceptibility contrast (DSC) MRI can be used to study tissue perfusion, there are potential technical problems in MMS. This study inv...
متن کاملNeuropsychological and perfusion MR imaging correlates of revascularization in a case of moyamoya syndrome.
Serial neurocognitive and perfusion MR imaging findings are described in the perioperative course of a 48-year-old woman with a superficial temporal artery to middle cerebral artery bypass for right hemispheric ischemia due to moyamoya syndrome. Neurocognitive testing reflected both global and focal cerebrovascular dysfunction, which suggests that perfusion augmentation following surgical revas...
متن کاملEcho-planar perfusion MR of moyamoya disease.
PURPOSE Our goal was to assess the value of perfusion MR imaging by using a single-shot echo-planar technique to evaluate the hemodynamics of moyamoya disease. METHODS We performed echo-planar perfusion studies in 19 patients with a 1.5-T unit, using a free-induction-decay echo-planar sequence for 14 examinations and a turbo-gradient-spin-echo echo-planar sequence for five examinations. After...
متن کاملAcute perfusion MR imaging in a HaNDL-like syndrome.
Case Report A 44-year-old right-handed man, with no history of migraine or cardiovascular risk factors, developed acute numbness and weakness involving the right leg and ascending to the right arm and the face, with aphasia and right homonymous hemianopsia. The symptoms cleared within 8 h. Cerebral MR imaging performed 2 h after the onset of symptoms – including T 2 diffusion-weighted fluid-att...
متن کاملCerebral hemodynamics in Moyamoya disease: correlation between perfusion-weighted MR imaging and cerebral angiography.
BACKGROUND AND PURPOSE In Moyamoya disease, the relationship between cerebral hemodynamics and angiographic findings has not been fully evaluated. The purpose of this study is to evaluate hemodynamics in Moyamoya disease with perfusion-weighted MR imaging (PWI) and cerebral angiography. METHODS Twenty patients with Moyamoya disease were the subjects. Mean transit time (MTT) derived from PWI w...
