DSA在肝动脉造影中的技术分析

Technique Analysis of the DSA Value and Effectiveness in Hepatic Arteriography

目的:分析肝动脉造影中影响DSA图像质量的相关因素,探讨DSA在肝动脉造影的价值及效果。方法:选择36例肝肿瘤患者,Seldinger方法经股动脉插管,用RH造影导管行肝动脉造影。结果:36例患者的192幅图像中,甲级片178幅,占92.7%;乙级片9幅,占5.3%;丙级片5幅,占2%。结论:选择性应用图像后处理功能处理乙丙级片,图像均有好转并能达到诊断要求。

Objective To analyze the correlation factors affecting DSA picture quality and to investigate the DSA value and effectiveness in hepatic arteriography. Methods 36 cases with liver tumor were analyzed through femoral artery intubatton with Seldinger and had hepatic arteriography with RH catheter. Results In the 192 images of 36 cases, the percentage of first-rate image was 92.7%, the second-rate image （9/192） was 5.3%, the third-rate image （5/192） was 2%.Conclusion All of the second-rate images and the third-rate images which were handled with selective image postprocessing can improve picture quality and can reach diagnosis request.
