摘　　要：目的探讨多层螺旋CT血管造影（MDCTA）对主动脉夹层的诊断价值.方法：对连续55例临床疑似主动脉瘤患者进行了MDCTA检查,采用多层面重建（MPR）曲面重建（CPR）和容积显示（VR）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28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：MDCTA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.Objectiveto investigate the diagnostic value of multi-slice spiral CT angiography （MDCTA） in the diagnosis of aortic dissection. Methods：From September 2013 to August 2015, 55 consecutive patients with clinically suspected aortic aneurysm underwent MDCTA examination, using multiple planar reformation （MPR）, and CPR, volume reconstruction （VR） and other post-processing technologies. Data were analyzed in the comparison with the original cross-sectional image. Results：Using MDCTA, a total of 28 cases were diagnosed with aortic dissection. Aortic dissection type and scope, the location of the intimal rupture, true and false lumen and thrombus, main involved vessels were assessed. Results were consistent with clinical diagnosis. Conclusion：MDCTA is a reliable and accurate method in the assessment of aortic dissection, and can be used as the first choice for the diagnosis of suspected aortic dissection
