The purpose of this study was to assess the utility high-field magnetic resonance (MR) imaging as a quantitative tool for estimating cerebral circulation in patients with moyamoya disease.Eighteen disease who were scheduled undergo revascularization surgery and 100 healthy volunteers examined using T2-reversed MR performed 3-tesla system. Ten 18 underwent second between 1 year 3 years after revascularization. Magnetic images obtained statistically analyzed compared those volunteers. findings also correlated results single-photon emission computerized tomography conventional angiography studies. Transverse lines white matter (medullary streaks) observed almost all persons. In volunteers, diameter sizes medullary streaks increased significantly age (p < 0.001). Multiple logistic regression analysis revealed that age-adjusted streak diameters larger Diameter severity hypoperfusion 0.001) higher angiographically determined stage decreased 0.001).The increases appear represent vessels dilated due hypoperfusion. High-field is useful disease.
