| 摘 要： | 目的: 探讨64排螺旋CT血管造影对主动脉夹层的诊断价值.方法: 2005年9月至2006年9月对连续88例临床疑似主动脉瘤患者进行了64排螺旋CT血管造影检查,采用多层面重建(MPR);曲面重建(CPR);容积显示(VR)和仿真内镜(VE)等多种后处理技术并结合原始横断增强图像进行综合分析.结果: MDCTA共显示主动脉夹层32例,可以准确评估主动脉夹层的分型及范围、内膜剥离、破口位置、真假腔及血栓情况、主要分支血管开口等,符合临床诊断要求.结论: 64排螺旋CT血管造影术对主动脉夹层的评价是可靠和准确的,可作为目前对临床疑似主动脉夹层筛查的首选影像诊断方法之一.

| Abstract: | Objective: To evaluate the diagnostic value of 64 multi-detector helical CT angiography in aortic dissection.Methods: 88 cases suspected dissection of aortic dissection were performed with MDCTA.The data was transmitted to ADW4.2 workstation,and reconstructed by MPR,VR,CPR,VE and generally analyzed with original axial images.Results: All the 32 aortic dissection were demonstrated clearly by MDCTA,and it can reveal the types and shape of aortic dissection.The true and false lumen and the intimal flap of aortic dissection were clearly showed.The position,size and shape of lacuna and its relationship with aortic branches,were clearly demonstrated from the cavities.Conclusion: 64-MDCTA is reliable and accurate in evaluating aortic dissection,gradually becomes one of the first modality diagnose in aortic dissection. |
