【摘要】：目的探讨双源256层螺旋CT双能量扫描对主动脉壁间血肿的诊断价值。方法回顾分析2012年10月至2014年8月期间主动脉壁间血肿CT影像检查资料。41例主动脉壁间血肿患者,均行双源256层螺旋CT双能量直接增强扫描诊断,并对原始数据进行图像后处理,包括虚拟平扫、多平面重建、曲面重建、最大密度投影等。结果主动脉壁间血肿致主动脉壁增厚,增厚主动脉壁均大于5 mm,其中新月形增厚39例,环形增厚2例。30例主动脉壁可见钙化斑块,25例可见钙化内膜内移,32例可见主动脉壁溃疡龛影,3例见内膜渗漏,无1例见内膜撕裂破口。合并单纯胸腔积液8例,胸腔积液并心包积液2例。结论双源256层螺旋CT双能量扫描能快速、准确、无创地诊断主动脉壁间血肿,可为临床制定合理治疗方案提供重要的信息。
[Abstract]:Objective to evaluate the diagnostic value of dual-source 256-slice spiral CT dual-energy scan in the diagnosis of aortic intermural hematoma. Methods the CT imaging data of 41 patients with aortic intermural hematoma from October 2012 to August 2014 were retrospectively analyzed. Double source 256-slice spiral CT double energy direct enhanced scanning diagnosis was performed, and the original data were processed by image post-processing, including virtual plain scan, multi-plane reconstruction, surface reconstruction, and so on. Results Aortic wall thickening caused by intermural hematomas was more than 5 mm, and crescent thickening was found in 39 cases. Circular thickening was seen in 2 cases. Calcified plaques were seen in aortic wall in 25 cases, calcified intimal migration was seen in 32 cases, and leakage of intima was seen in 3 cases. No rupture of intima was found in 1 case. 8 cases were complicated with pleural effusion. Conclusion Dual-source 256-slice spiral CT dual-energy scan can diagnose aortic intermural hematoma quickly, accurately and noninvasively, which can provide important information for clinical treatment.
