Moyamoya disease (MMD) is deļ¬ned in angiography as a
chronic progressive steno-occlusion of internal carotid
arteries with characteristically abnormal vascular
networks at the base of the brain. In this study, by
analyzing the rs-fMRI data with the iteration algorithm
described in this paper, the perfusion deficit areas
that had long TTP value could be detected
non-invasively. The results of our technique match well
with TTP maps from DSC-MR and could be a good
alternative for monitoring long-term changes of cerebral
blood flow pattern in MMD frequently.
