目的：探讨主动脉壁内血肿多排螺旋CT(MDCT)的诊断价值及动态变化规律。方法回顾性分析48例主动脉壁内血肿患者的CT增强扫描资料，采用多平面重组(MPR)、曲面重组(CPR)、最大密度投影(MIP)等图像重建技术进行分析。结果48例诊断为主动脉壁内血肿的患者中，随访43例，进展的有8例，非进展者有35例。高龄，男性，肥胖，高血糖，吸烟及CT随访所见危险征象为主动脉壁内血肿进展的危险因素。结论 MDCT能准确诊断主动脉壁内血肿，并可以评估其进展的危险性。

Objectives To explore Multiple Detector Spiral CT(MDCT) application in diagnosis of aortic intramural hematoma (IMH) and the necessity for follow-up study. Methods A retrospective analysis of 48 patients with aortic intramural hematoma was performed. All patients underwent enhanced CT scan. Image reconstruction techniques were used for analysis, such as multi-planar reconstruction (MPR), curved planar reconstruction (CPR), maximum intensity projection (MIP),ect. Results In 48 patients with IMH, 43 patients finished the follow-up study,8 cases were progress ive and 35 cases were not. Age, male, obesity, diabetes, smoking and CT signs were the risk factors during the progression of IMH. Conclusion MDCT can accurately diagnose the aortic intramural hematoma, and to assess the risk of progress.
