目的:探讨16层螺旋CT血管造影(MSCTA)在烟雾病诊断中的应用。方法:20例烟雾病患者行MSC-TA检查,在工作站上分别行容积再现、最大密度投影、多平面重组进行血管重建,其中3例患者行DSA检查。结果:MSCTA清晰显示不同程度颈内动脉、大脑前动脉、大脑中动脉起始段狭窄、闭塞及脑底部纤细迂曲的烟雾状异常血管网。结论:MSCTA可清晰显示烟雾病异常血管、侧枝循环,并且检查方法简单、快捷,可为烟雾病的诊断和临床治疗提供重要的参考依据。
Objective: To explore the application of 16-slice spiral CT angiography (MSCTA) in the diagnosis of moyamoya disease. Methods: Twenty patients with moyamoya disease underwent MSC-TA examination. Volume reconstruction, maximum density projection and multiplanar reconstruction were performed on the workstation. Three patients underwent DSA. Results: MSCTA clearly shows varying degrees of internal carotid artery, anterior cerebral artery, middle cerebral artery stenosis at the beginning, occlusion and sinuatus at the bottom of the smoky vascular network. Conclusion: MSCTA can clearly show abnormal moyamoya disease and collateral circulation, and the examination method is simple and quick. It can provide an important reference for the diagnosis and clinical treatment of moyamoya disease.
