目的：探讨16层CT血管造影（16SCTA）在诊断烟雾病中的应用价值。方法23例烟雾病患者均行16层CT平扫和16SCTA检查，图像后处理采用多平面重组（MPR）、容积再现（VR）和最大密度投影（MIP）。其中5例同时行数字减影血管造影（DSA）检查。结果16层CT平扫显示脑梗死8例，脑出血7例，脑出血合并脑梗死6例，脑实质未见异常2例。16SCTA均清晰显示发生狭窄、闭塞的颈内动脉、Willis环血管近侧端，以及明显增多、扩张的脑底部侧支血管影，其中双侧颈内动脉闭塞8例，单侧大脑中动脉闭塞13例，单侧颈内动脉闭塞伴同侧大脑后动脉狭窄2例。侧支血管表现为相应血管及其分支的粗大、增多、迂曲。5例DSA表现与16SCTA结果一致。结论16SCTA可以清晰显示烟雾病病变血管的特点，检查方法简单、快捷，可为临床诊疗提供重要的诊断依据。

Objective To investigate the 16-slice CT angiography(16SCTA) in the diagnosis of moyamoya dis-ease. Methods All 23 cases of patients with moyamoya disease underwent 16-slice CT scan and 16SCTA examina-tion, the angiograms obtained were processed to perform volume rending(VR), maximum intensity projection(MIP) and multiplanar volume reformation(MPR). Among them 5 cases underwent digital subtraction angiography(DSA) examina-tion. Results 16-slice CT scan showed 8 cases of cerebral infarction, 7 cases with cerebral hemorrhage, 6 cases complicated with cerebral infarction and cerebral hemorrhage, cerebral parenchyma was normal in 2 cases. In all of the 23 patients, the 16SCTA clearly revealed stenosis, occlusion of the internal carotid artery, Willis ring vessel proxi-mal end, and significantly increased, expanding the base of the brain collateral vessels. The bilateral carotid artery occlusions were in 8 cases, unilateral middle cerebral artery occlusions in 13 cases, unilateral internal carotid artery occlusions and ipsilateral posterior cerebral artery stenosis in 2 cases. The performance of the corresponding collateral vessels and their branches, coarse, increased tortuosity. DSA manifestations of 5 cases were accordant with 16SCTA results. Conclusion The 16SCTA can clearly show the characteristics of lesions of moyamoya disease, and it is sim-ple, fast, and can provide the important diagnosis evidence for clinical diagnosis and treatment.
