多层螺旋CT血管成像技术在主动脉夹层动脉瘤诊断中的应用价值分析

Analysis of application value of the multi-slice spiral CT scanner in the diagnosis of dissecting aneurysm of aorta

目的探讨多层螺旋CT血管成像技术(MS-CTA)在主动脉夹层动脉瘤诊断中的临床特点和应用价值。方法采用MS-CTA对在本院接受治疗的46例主动脉夹层动脉瘤患者进行检查,并将获得的原始数据进行多平面重组、最大密度投影、曲面重建以及容积再现技术进行处理。最终根据重建图像结果进行确诊,并与传统的数字减影血管造影(DSA)结果进行分析比较。结果 MS-CTA结果表明所选的病例中Ⅰ型13例,Ⅱ型24例,Ⅲ型9例。功能检查发现MS-CTA在主动脉夹层检查中能够清晰显示血管病变和累及范围、对病例中血栓形成、管壁钙化及破裂情况的检查结果与DSA检查差异均无统计学意义。结论 MSCT是主动脉夹层动脉瘤诊断最有价值的诊断方法之一。

Objective To explore and analyze the potential applications value of multislice spiral CT（MSCT） scanner for patients in clinical suffered with dissecting aneurysm of aorta. Methods Altogether 46 patients suffered from the disease of dissecting aneurysm of aorta in this research would be voluntary and experienced multi-slice spiral CT angiography scan. After which, multiple planar reconstruction （MPR）, curve planar reconstruction （CPR）, maximum intensity projection （MIP）, and volume rendering （VR） were applied to process the obtained date. Based on which all the cases were diagnosed and compared with clinically-proven results. Results DeBakey types of MSCT examination showed the number of the type Ⅰ , type Ⅱ and type Ⅲ were 13, 24, 9 eases, respectively. The results of muhisliee spiral CT （MSCT）seanner showed that it had great potent to determine the involvement and scope of aortic dissection, wall calcification, intraluminal thrombus, as well as rupture in a comparatively higher diagnostic manner which showed a high consistency with digital subtraction angiography （DSA） without significant difference from thestatistical point of view （P〉0.05）. Conclusion MSCT is one of the most valuable diagnostic methods for the diagnosis of aortic dissecting aneurysms.
