【摘要】 目的:探讨间接门脉DSA与16排多层螺旋CT门脉造影(SCTP)的门脉成像差异。方法:对30例肝占位病变伴肝硬化患者均经肠系膜上动脉或腹腔动脉行间接门脉DSA和SCTP三维成像,对比分析2种影像质量差异。结果:不同程度肝硬化的SCTP三维成像质量及显示门脉4~5级及分支破坏要优于间接门脉DSA,但显示门脉分支推移改变2种方法无差异,而在显示动静脉瘘和门脉癌栓方面,间接门脉DSA由于其动态显像性要优于CT门脉造影。结论:在常规间接门脉DSA显示门脉欠佳时可选择SCTP检查以指导临床工作。更多还原

【Abstract】 objective: The features of indirect portography DSA and Light Speed 16 Multiple Slice spiral-CT portography (SCTP) in portography imaging were comparatively studied.Methods: 30 patients with space occupying diseases of liver accompanied by cirrhosis were examined by indirect portography DSA and 3D-SCTP.Results: 3D-SCTP could visualize the 4-5 grades branches of portal vein. The display rate of destruction and deviation of distal PV in 3D-SCTP was higher than in indirect portography DSA. There was no difference in showing deviated branches of portal vein. Indirect portography DSA can play more important role in arteriovenous fistula than CT portography.Conclusion: It was suggested that 3D-SCTP was helpful when display of portal vein by conventional indirect portography DSA is not very clear.更多还原
