摘要
目的:评价主动脉夹层的多层螺旋CT表现和诊断价值。方法:回顾性分析18例主动脉夹层病例资料,所有病人均进行16层螺旋CT平扫和CTA检查,并进行多平面重组和3D成像处理。结果:所有病例均显示真假腔的大小形态,14例显示内膜片,5例显示内膜钙化内移,3例显示假腔内血栓形成。3D图像均显示了主动脉夹层的全貌。结论:多层螺旋CT对诊断和评价主动脉夹层具有重要价值,具有快速、无创和准确的优点,多层螺旋CT应该成为诊断主动脉夹层的首选方法。
Objective： To evaluate the manifestations and diagnostic value of multi-- slice CT （MSCT） in aortic dissection（AD）. Methods： 18 cases of aortic dissection were retrospectively analyzed. All cases were examined with MSCT plain scanning and CTA and post--processed using multiplanar reformation（MPR）and 3D technique. Results： True and false lumens were showed in all eases, intimate flap in 14 eases, intimate flap calcification and displace in 5 cases, intraluminal thrombus in 3 cases. 3D images displayed the whole shape of AD. Conclusion： MSCT has an important application value in diagnosing and evaluation AD, which is quick, hurtles and accurate. It could be used as the first choice imaging technique in diagnosing AD.
