摘　　要：目的评价多排螺旋CT在主动脉夹层诊断中的应用价值。方法采用多排螺旋CT对40例主动脉夹层患者进行对比增强检查,运用多平面重建(MPR)、曲面重建(CPR)、最大密度投影(MIP)和容积显示(VR)等多种后处理技术重建显示图像并进行分析。结果本组40例主动脉夹层患者中,I型5例、Ⅱ型2例和Ⅲ型33例,CT增强扫描及重建可清晰地显示主动脉增宽、动脉壁钙化、动脉夹层的真假腔、破口位置及内膜剥离范围。结论多排螺旋CT对显示主动脉夹层具有无创、快速检查的优势,可以全面显示主动脉夹层的病变和解剖细节,有助于临床术前评估、制定治疗方案、降低手术风险,是一种可靠的影像学诊断方法。Objective To evaluate the diagnosis value of 16-slice spiral CT in aortic dissection. Methods 40 patients suffering from aortic dissection were examined by contrast-enhanced MSCT. The data were reconstructed by multiplanar reconstruction（MPR）, curved planar reconstruction（CPR）, volume rendering（VR）, maximum intensity projection（MIP）. Results According to De Bakey＇S classification, De Bakey type I in 5 cases, type II in 2 cases and type Ⅲ in 33 cases were founded in the 40 cases. Enhanced CT scanning and reconstruction can clearly display aortic enlargement, arterial wall calcification as well as true or false cavities, crevasse position and intima stripping range of artery dissection. Conclusion 16-slice spiral enhanced scanning can display the details of aortic dissection. It was a reliable and effective imaging diagnostic way in preoperative evaluation, making the right operative modality and decreasing the perioperative mortality.
