目的：观察烟雾病（MMD）的磁共振成像（MRI）与磁共振血管成像（MRA）表现，探讨 MRI各序列与 MRA对 MMD的诊断价值。方法回顾性分析明确诊断的18例MMD患者的临床资料并分析其影像学征象，18例采用常规头部MRI平扫，包括横断T1WI、T2WI、DWI、FLAIR及矢状T2WI序列；MRA采用三维时间飞跃法（3D-TOF）。结果18例 MRA结果均显示双侧颈内动脉远端、大脑前动脉及大脑中动脉近端不同程度狭窄、闭塞，其中，并发脑梗死11例，出血3例，半卵圆中心、放射冠区及侧脑室周围缺血灶7例，脑萎缩4例，脑软化灶并胶质增生8例。结论 MRI及 MRA检查对 MMD诊断、治疗具有重要价值。

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.
