MSCT血管成像在主动脉粥样硬化及主动脉瘤和夹层诊断中的应用价值

Clinical application of multi-slice spiral CT angiography in the diagnosis of aortic atherosclerosis, aortic dissection and aortic aneurysm

目的:探讨多层螺旋CT血管成像在主动脉粥样硬化及主动脉瘤和夹层诊断中的应用价值。方法:对63例疑有主动脉病变的患者行6层螺旋CT主动脉增强血管成像扫描,然后将数据送工作站作多平面重建(MPR)、曲面重建(CRP)、容积再现(VRT)、最大密度投影法(MIP)和仿真内窥镜重建(VE)。结果:63例病人中,正常者7例,异常者56例。异常病例中单纯主动脉钙化4例,主动脉粥样硬化52例,并发主动脉瘤5例,并发主动脉夹层7例。结论:多层螺旋CT主动脉血管成像对诊断主动脉粥样硬化及主动脉瘤和夹层诊断具有快速、准确、创伤小等优点,可作为诊断主动脉病变的首选检查方法之一。

Objective： To explore the value of multi-slice spiral CT angiography in the diagnosis of aortic atherosclerosis, aortic dissection and aortic aneurysm. Methods： 63 patients suffered from aortic disease were scanned by CT angiography with the 6-slice spiral CT, and the data was transferred to the workstation for image post-processing including multiple planar reformation（MPR）, curved planar reformation（CPR）, volume rendering technique（VRT）, maximum intensity projection（MIP）, visual endoscopy （VE）. Result： Fifty-two cases were suffered from aortic atherosclerosis （including 5 aortic aneurysm, 7 aortic dissection）, 4 were only suffered from calcification of aortic wall and 7 were normal. Conclusions： Multi-slice spiral CT angiography of aorta is accurate and non-invasive for diagnosing aortic atherosclerosis, aortic dissection and aortic aneurysm, and it can be a preferred method for the aortic diseases.
