【摘要】 目的探讨64排螺旋CT血管造影(CTA)技术在下肢动脉损伤中的应用价值。方法选择2012年2月至2013年4月于我院行CTA检查的32例下肢动脉损伤患者,利用LEONARDO工作站进行数据分析,处理方式包括曲面多平面重建、容积重建和最大密度投影,并与原始图像相结合,进行全面分析。结果 32例患者病变血管的程度、范围以及形态良好,血管轮廓在CTA重建图像中十分清晰。出现血栓闭塞性脉管炎的患者占4例,出现假性动脉瘤的患者占2例,出现腘动脉瘤的患者占5例,出现下肢动脉粥样硬化性病变的患者占21例。结论 64排螺旋CT血管造影技术在下肢动脉损伤诊断中具有很大的应用价值。更多还原

【Abstract】 Objective To investigate the application value of the 64-slice spiral CT angiography(CTA) technique in lower extremity arterial injury. Methods From February 2012 to April 2013 CTA examination were performed in 32 cases with lower extremity arterial injury, LEONARDO workstation was used for data analysis, and processing methods included curved MPR, volume rendering and maximum intensity projection, and then combined with the original image, to conduct a comprehensive analysis. Results Vascular lesion extent, scope and form were good in 32 patients, and a good outline blood vessels in CTA reconstructed image is very clear. There were 4 cases with thromboangiitis obliterans, 2 cases with pseudoaneurysm, 5 cases with popliteal aneurysm, 21 cases with lower extremity atherosclerotic lesions. Conclusion 64-slice spiral CT angiography has great application value in the diagnosis of lower extremity arterial injury.更多还原
