目的:探讨128层螺旋CT血管成像在主动脉夹层的诊断价值。方法:15例主动脉夹层,全部进行128层螺旋CT胸腹联合平扫及增强,并将原始数据在工作站进行多平面重建(MPR)、阴影表面显示(SSD)、最大密度投影(MIP)及容积处理(VR)等后处理。结果:15例均很好地显示了主动脉夹层全程及其分支,真腔、假腔、内膜片及夹层动脉瘤的部位、范围。结论:128层螺旋CT血管成像是诊断主动脉夹层准确、快捷、有效的首选检查方法,具有较高的临床应用价值。
Objective: To investigate the diagnostic value of 128-slice spiral CT angiography in aortic dissection. Methods: Fifteen cases of aortic dissection were scanned with 128-slice spiral CT combined with chest and abdomen. The raw data were analyzed by multi-plane reconstruction (MPR), shadow surface display (SSD), maximum density projection (MIP) Volume processing (VR) and other post-processing. Results: All the 15 cases showed the location and extent of the entire aortic dissection and its branches, true cavity, false lumen, intima and dissecting aneurysm well. Conclusion: 128-slice spiral CT angiography is the first choice to diagnose aortic dissection accurately, quickly and effectively, which has high clinical value.
