64层螺旋CT血管成像对主动脉粥样硬化穿透性溃疡的应用价值

The Diagnostic Value of 64-MSCT Angiography for Penetrating Atherosclerotic Aortic Ulcerres

目的探讨64层螺旋CT血管成像(64-MSCTA)在穿透性粥样硬化性主动脉溃疡(PAU)中应用价值。方法 14例PAU均进行了64-MSCTA胸腹联合检查,将原始数据在工作站进行MPR、CPR、MIP及VR等后处理。结果 14例患者CT横轴位原始图像、MPR图像均能很好显示PAU的部位、数目、大小、深度、形态及并发症(包括壁内血肿、假性动脉瘤及主动脉破裂)。MIP及VR图像可任意角度立体显示主动脉全程轮廓、钙化斑块及溃疡形态。结论主动脉MSCTA是诊断主动脉粥样硬化穿透性溃疡准确、快捷、有效的首选检查方法,对指导临床治疗具有的很重要的意义。

Aim To investigate the diagnostic value of 64-MSCT angiography( 64-MSCTA) for penetrating atherosclerotic aortic ulcer( PAU). Methods 64-MSCT angiography study was performed in 14 patients with penetrating atherosclerotic aortic ulcer. The volume data was transferred to workstation for image post-processing including MPR, CPR,MIP and VR. Results The location,size,number,depth and complications of PAU in all patients were satisfactorily showed on Axial view and MPR image. The complications of PAU included intramural hematoma,pseudoaneurysm or aortic rupture. The whole aorta outline,ulcer shape and calcified plaque of 14 patients were 3D demonstrated well on MIP and VR image. Conclusion MDCTA is accurate,fast and effective for the diagnosis of PAU.
