摘要
目的:评价64层螺旋CT血管造影在主动脉夹层动脉瘤中的应用价值。材料与方法:收集主动脉夹层动脉瘤CT血管造影41例,原始横断面图像结合MPR、MIP、VR进行图像分析。结果:原始横断面图像能明确主动脉夹层动脉瘤的诊断,能清晰显示真假腔41例(100%),分离移位的内膜片41例(100%)、内膜破口37例(90.2%)、主动脉分支受累21例(51.2%)、假腔内血栓形成27例(65.9%);MPR、MIP及VR能显示病变的空间情况,对原始横断面图像是很好的补充。对横断面图像较难显示小的内膜破裂口,MPR图像能清楚显示。MIP及VR可以立体、直观地显示主动脉夹层情况。结论:64层螺旋CT血管造影能明确诊断主动脉夹层动脉瘤,具有快速、准确、无创的特点,是诊断主动脉夹层动脉瘤的首选检查方法。
Objective：To evaluate clinical application value of 64-detector spiral CT angiography for dissecting aneurysm of aorta（ADA）.Material and methods：CT angiography was performed in 41 cases with ADA,Original axial images combined with MPR,MIP and VR were analyzed.Results：The original axial images can diagnose ADA definitely and clearly show true lumen and false lumen（100%）,intimal flap（100%）,entry of intimal tear（90.2%）,the involvement of branches of aortic（51.2%） and thrombosed false lumen（65.9%）,The images of MPR,MIP and VR can show space conditions of aorta and is a very good supplement to the original axial images.The images of MPR can clearly show those entries of intimal tear that the axial images show difficultly,The images of MIP and VR can show the condition of ADA spatially and intuitively.Conclusion：64-detector spiral CT angiography can diagnose ADA definitely and are accurate,quick and non-trauma,so the examination may be as the first choice method in diagnosis of ADA.
