Abstract:
Objective To explore the value of MRI sequence and MRA for diagnosis of moyamoya disease(MMD).Methods Retrospective analysed of 1 8 cases of moyamoya disease clinical datas,1 8 cases were used routine head MRI scan,including T1 WI, T2WI,DWI,transverse and sagittal T2WI sequence FLAIR;MRA three dimensional time of flight(3D-TOF).Results 18 cases of patients with MRA showed bilateral internal carotid artery,anterior cerebral artery distal and proximal middle cerebral artery steno-sis or occlusion of signs.Among them,1 1 cases were found with secondary cerebral infarction,3 cases of cerebral hemorrhage,7 ca-ses of centrum semiovale,corona radiata and periventricular cerebral ischemia,4 cases of cerebral atrophy,8 cases of cerebral soften-ing and gliosis.Conclusion MRI and MRA examination have important value in the diagnosis of moyamoya disease,treatment.
