[摘要]目的：认识多层螺旋CT血管成像(MSCTA)对主动脉夹层的诊断价值。方法：收集我科2008年1月~2010年10月经手术确认及MSCTA、彩超、MRI相结合共同诊断的24例主动脉夹层病例进行回顾性分析总结。结果：24例主动脉夹层均显示双腔和撕裂的血管内膜片，MSCTA能清楚显示血管壁钙化及假腔内附壁血栓，部分显示主动脉水平裂破口。其中DeBakeyⅠ型8例，Ⅱ型2例，Ⅲ型14例。结论：螺旋CT增强扫描及图像重建能迅速、准确诊断主动脉夹层，为临床治疗提供客观依据。

[Abstract]Objective：To assess the value of MSCTA in aortic dissection (AD) diagnosis. Methods 4 cases of AD were diagnosed by operation,MSCTA,Ultrasound and MRI from January 2008 to October 2010.Retrospective analysis was employed for the assay. Araesults：We found that the image of 24 cases of AD showed the double-lumen and the patches in the vessel infimale and the calcium patches in thevessel or the thrombus in artificial cavum particularly found on the bursting breach of AD were showed very cldarly . Among them,Type I had 8 cases, TypeII had2 cases typeIII 14 cases. Conclusion SCTA and reconstruction of image not only can diagnose AD accurately and rapidly but also provide objective proof to diangnosis and therapy of coinic ......
