摘　　要：目的：探讨64排螺旋CT血管成像（ CTA）在烟雾病诊断中的应用价值。方法：回顾CT平扫和CTA检查的16例烟雾病患者资料,分析其影像学特点。结果：脑出血8例,脑梗死2例,脑出血及脑梗死2例,脑萎缩及脑出血2例,2例未见明显异常。 CTA显示双侧大脑前中动脉狭窄、闭塞4例,单侧3例。双侧颈内动脉、大脑前、中动脉C1段、A1或A1-A3段、M1段不同程度狭窄、闭塞9例。合并大脑后动脉狭窄3例。16例均显示脑底异常血管网。侧支血管表现为相应血管及其分支粗大、增多,迂曲延长。结论：CTA可提供烟雾病确切的诊断,是一项实用、有效的技术,对烟雾病分析评价有重大临床价值。Objective：To investigate the clinical value of 64 detector spiral CT angiography（CTA） in the diagnosis of moyamoya disease. Methods：The CT scan and CTA examination data of 16 cases with moyamoya disease were retrospectively analyzed. their imaging features were compared. Results：Cerebral hemorrhage in 8 cases. cerebral infarction in 2 cases. cerebral hemorrhage and infarction in 2 cases. and brain atrophy and cerebral hemorrhage in 2 cases were found,2 cases with no obvious abnormalities. The CTA showed that bilateral anterior and middle cerebral artery stenosis and occlusion in 4 cases and unilateral stenosis and occlusion in 3 cases. The different degree of stenosis and occlusion in bilateral internal carotid artery and C1. A1 or A1-A3 and M1 segment of anterior and middle cerebral artery of 9 cases were found. The merger of posterior cerebral artery stenosis in 3 cases and moyamoya in 16 cases were found. The large increasing and circuity and extending blood vessel in collateral vessels were showed. Conclusions：CTA is an efficient and practical technique in diagnosing moyamoya disease. which has great clinical value.
