烟雾病的磁共振成像

Magnetic resonance imaging of moyamoya disease

烟雾病是一种以双侧颈内动脉末端及其大分支血管进行性狭窄或闭塞，且在颅底伴有异常新生血管网形成为特征的慢性进行性脑血管病。作为一种无创性检查方式，MRI在烟雾病的诊断评价中发挥着重要作用。文章就MRI在烟雾病患者卒中亚型判断、确诊以及治疗评价等方面的应用进行了综述。

Moyamoya disease is a chronic progressive cerebrovascular disease which is characterized by progressive stenosis or occlusion at bilateral terminal portions of the internal carotid artery and its large branch vessels,and with an abnormal formation of new vascular network in skull base.As a noninvasive method,magnetic resonance imaging （MRI） plays an important role in the diagnosis and evaluation of moyamoya disease.This article reviews the application of MRI in the identification,diagnosis and treatment evaluation of the stroke subtypes in patients with moyamoya disease.
