摘要
目的探讨多层螺旋CT血管成像(MSCTA)诊断下肢动脉硬化性闭塞症(ASO)的方法及临床应用价值。资料与方法对42例临床疑有ASO患者行MSCTA检查,数据传输至AW4.2工作站,行容积再现(VR)、最大密度投影(MIP)、曲面重建(CPR)、仿真内镜(VE)、高级血管分析(AVA)等多种后处理并结合原始图像进行综合分析。结果42例的血管重建图像对ASO有特征性显示,15例患者术中所见与MSCTA一致。结论MSCTA对下肢动脉病变的显示具有独特的优势,已逐渐成为诊断血管病变及评估手术疗效的首选影像学检查方法。
Objective To discuss the clinical value of 16-slice CT angiography in diagnosis of arteriosclerotic occlusive disease of lower limb. Materials and Methods 42 cases clinically suspected with arteriosclerotic occlusive disease of lower limb were performed with MSCTA. The data was transmitted to ADW4.2 workstation, and reconstructed by VR, MIP, CPR, VE, AVA and generally analyzed with original axial images. Results 42 cases were performed successfully, and characteristic features depicted. Results of MSCTA in 15 cases were identical with results of operation. Conclusion MSCTA is valuable to demonstrate arterial disease in lower limb, gradually become the first modality to diagnose and evaluate the curative effect.
