摘　　要：目的探讨128层螺旋CT血管造影(MSCTA)及其后处理技术在诊断烟雾病中的价值。方法 17例烟雾病病例均行CT平扫及MSCTA检查,所得原始容积数据在ADW4.3工作站上采用容积再现(VR)、最大密度投影(MIP)、多平面容积重建(MPVR)技术重组各种图像。结果 CT平扫可显示颅内缺血及出血性改变。MSCTA及后处理成像可显示不同程度的颈内动脉和(或)大脑前动脉、大脑中动脉狭窄或闭塞。17例均可显示颅底部异常增生的侧支血管网。结论 MSCTA可清晰显示烟雾病的血管改变特点,而重建图像可直观显示病变周围空间关系。此检查方法方便、快捷、无创,可为临床诊断及治疗提供重要依据。Objective To evaluate the value of 128-slice spiral CT angiography （MSCTA） and post-processing techniques in diagnosing moyamoya disease.Methods CT plain scanning and MSCTA volume scanning were performed in 17 patients,The raw data obtained were reorganized by volume rendering （VR）,maximum intensity projection （MIP） and multiple volume reconstruction （MPVR） on the ADW4.3 workstation.Results CT plain scan can show changes of ischemic and hemorrhagic in brain. MSCTA and post-processing imaging can show different degrees of stenosis or obstruction in internal carotid artery （ICA） and （or） anterior cerebral artery（ACA）,middle cerebral artery（MCA）. All 17 cases can show abnormal proliferation of collateral vascular network in skull base.Conclusion MSCTA can clearly show the vascular changes in moyamoya disease＇s characteristics,and lesions of the reconstructed image can be visually displayed around the spatial relations. This inspection method is convenient,quick,noninvasive,and can provide an important basis for clinical diagnosis and treatment.
