摘　　要：目的:探讨双源CT去骨减影3D-CTA对脑血管病的诊断价值。方法:回顾性分析60例头颈CT血管成像检查的影像资料,使用西门子双源CT机。获得原始图像传送到工作站进行VR、MPR、CPR、MIP图像后处理重建,并对照手术或DSA结果评估其诊断价值。结果:本组60例,正常19例,异常41例,其中动脉瘤9例,动静脉畸形(AVM)3例,脑动脉狭窄和闭塞29例,与手术及DSA符合率100%。结论:双源CT去骨减影3D-CTA对多种脑血管病的诊断具有肯定的临床应用价值。Objective： To explore the diagnosis evaluation of DSCT with boneless subtraction 3D-CTA in cerebral vascular disease. Methods： DSCT with boneless subtraction 3D-CTA of 60 patients with suspected clinically cerebral vascular diseases were analyzed retrospectively all axial images were transferred to an external workstation. The reconstructed images were processed into volume rendering （VR）, multiplanar reconstruction （MPR） and maximum intensity projection （MIP）, the values were valuably compared with the results of surgery or DSA. Results： 9 cases were aneurysms, 29 cases were cerebral artery stenos is or occlusion, 3 cases were AVM, 19 cases were normal. Conclusion： DSCT with boneless subtraction 3D-CTA is a valuable diagnostic method for various cerebral vascular diseases
