目的探讨256层螺旋CT血管成像对主动脉夹层的诊断价值。方法回顾性对86例主动脉夹层患者CT征象。在工作站后处理采用容积再现法（VR）、多平面重建（MPR）、最大密度投影(MIP)及曲面重建（CPR）等处理技术。结果86例主动脉夹层中均能明确显示真假腔及内膜片，71例典型主动脉夹层三维成像均能显示明确破口,显示率为82.6%。根据DeBakey分型，本组86例主动脉夹层患者中显示I型10例(11.6%)，II型3例(3.5%)和III型73例(84.9%)。结论多层螺旋 CT能够快速、准确诊断主动脉夹层，能清晰的显示真假腔、内膜及受累血管范围，对临床治疗有着重要意义。

Objective To evaluate diagnostic value of 256-silice spiral CT angiography in aortic dissection. Methods Analize data of 86 aortic dissection cases by CTA. The data were reconstructed by volume rendering(VR),multiplanar reconstruction(MPR),maximum intensity projection(MIP)and curved planar reconstruction(CPR)and other reconstructions. Results The ture lumens,false lumens and the dissection menbranes were showed definitely in al 86 cases by CTA.The primary crevices were visible in 71 cases obviously(82.6%).According to DeBakey typing ,this group of 86 patients was composed of type I(10cases,11.6%) , type II (3cases,3.5%)和type III型(73cases,84.9%).Conclusion The features(including ture lumens,false lumens and the dissection menbranes)of aortic dissection can be diagnosed by 256-slice CTA fast and accurately and non-invasive ,and 256-slice CT can provide accurate imaging information for clinical therapy.
