摘　　要：目的:探讨MSCT及其后处理技术在主动脉壁内血肿(IMH)诊断中的应用价值。方法:采用GE 16层螺旋CT对11例AIH患者行平扫和CTA扫描。将采集的薄层数据在AW4.3工作站上行MPR和VR重建。结果:A型IMH 3例,B型IMH 8例。MSCT主要征象为:11例主动脉壁新月形或环形增厚大于5mm,呈等密度或高密度,无内膜片撕裂及真、假两腔形成;主动脉粥样硬化7例;内膜钙化内移4例;内膜渗漏3例;穿透性溃疡3例。结论:MSCT结合MPR和VR重建技术能准确、直观地显示IMH的范围和其它并发征象,对临床诊断和治疗有重要的指导意义。Objective：To study the application value of multi-slice spiral CT and postprocessing techniques in diagnosis of aortic artery intramural hematoma（IMH）.Methods：11 patients of IMH underwent plain scan and CT angiography by 16slice spiral CT of GE.The images of MPR and VR were reconstructed on the basis of axial scanning at AW4.3 workstation.Results：3 cases with Stanford A and 8 cases with Stanford B IMH were diagnosed.The main CT findings were as follows： Crescent or circular thickening（5 mm）of aortic wall with higher density or isodensity without intimal flap as well as true and false lumen（11 cases）;Atherosclerosis（7 cases）;Intimal calcification ingression（4 cases）;Intimal leakages（3 cases）;Penetrating ulcer（3 cases）.7 cases were observed complete regression.2 cases were observed incomplete regression.2 cases were observed to be dissecting aorta in progression.Conclusion：Combined application of MSCT and reconstruction of MPR and VR can display the range and other complicated signs of IMH accurately and directly.And provides important information for clinical diagnosis and treatment.
