主动脉瘤(夹层)的CT诊断

目的:探讨主动脉夹层CT诊断的标准及多层螺旋CT血管造影对其意义。材料与方法:采用GE公司lightspeed多层螺旋机,从胸骨切迹向下耻骨联合扫描发现主动脉夹层8例病例进行图像分析。结果:CT增强扫描加3D重建对主动脉夹层CT诊断率很高,比普通CT扫描获得的信息量大,可对主动脉夹层提出准确的分型,为临床治疗提供依据。结论:目前多层螺旋CT可以清楚显示主动脉分支受累及所致器官缺血性状况,有与介入造影金标准并驾齐驱的态势,并有很好的无创伤功能诊断价值。

Purpose： To discuss the diagnostic stand of aortic dissection （AD） hy cr and the significance of CrA. Materials and Methods. MSCT. lightspeed made by GE company was applied to scan from surastemal notch to symphysis pubica, eight cases of AD were found and their images were analyzed. Result： MSCT ＋ 3DR could get more messages than the common CT, it could improve the diagnostic rate of AD, provided accurate classification and evidence for clinic treatment. Conclusion： MSCY causing no injury could clearly show the effect of the branch of aorta and ischemic organ affected hy AD, and has the same featured as interventional angiography.
