【摘要】 目的:探讨64层CT血管成像(MSCTA)诊断下肢动脉硬化闭塞症(ASO)的方法和临床价值。方法:对46例临床疑有ASO患者行MSCTA检查,数据传至Wizard工作站,使用最大密度投影(MIP)、容积再现(VR)、曲面重建(CPR)等多种后处理方法,结合轴位原始图像进行综合分析。结果:46例血管重建图像显示了ASO特有的征象,13例手术患者与MSCTA结果一致。结论:MSCTA对下肢动脉硬化闭塞症的显示独具优势,对术前诊断及术后评价具有很高的临床价值。更多还原

【Abstract】 Objective:To discuss the clinical value of 64-slice CT angiography in diagnosis of arteriosclerotic occlusive disease of lower limb.Methods:46 cases with clinically suspected arteriosclerotic occlusive disease of lower limb were performed with MSCTA.The data were transmitted to Wizard workstation and reconstructed by MIP,VR,CPR,and generally analyzed with original axial images.Results:46 cases were performed successfully and the characteristic features were depicted.Results of MSCTA in 13 cases were identical with results of operation.Conclusion:MSCTA is valuable to demonstrate arterial disease in lower limb and,gradually,becomes the first modality to diagnose and evaluate the curative effect.更多还原
