摘　　要：目的:评价256层螺旋CT分步组合后处理技术在右膈下动脉(RIPA)成像中的价值。方法:对98例患者行腹部双期增强扫描,其中肝细胞癌12例,分别用A组:多平面重组(MPR)+最大密度投影(MIP);B组:MPR+容积再现(VR);C组:MPR+曲面重组(CPR)3种不同后处理组合方式观察RIPA。结果:98例患者的RIPA均能显示,A组对于RIPA起源及大体解剖的显示高于B组和C组,具有显著统计学差异(P<0.01)。结论:MPR+MIP分步组合后处理技术能很好的显示RIPA,可以作为经导管肝动脉化疗栓塞(TACE)术前准确评估其参与肝细胞癌肝外供血首选的无创性检查手段。Objective： To evaluate the value of combined different postprocessing techniques using 256 slice spiral CT for the visualization of right inferior phrenic artery（RIPA）.Methods： Double-phase contrast enhanced scan was performed in 98 patients including 12 cases of HCC to observe RIPA using three different postprocessing combination techniques.The cases were divided into three groups： Group A（MPR＋MIP）,Group B（MPR＋VR）,and Group C（MPR＋CPR）.Results： The ability of showing the origin and distribution of RIPA in Group A was higher than those in Group B and Group C.Conclusion： MPR＋MIP postprocessing techniques can display distribution of RIPA clearly,which can be used as a first choice and accurate noninvasive examination method to evaluate the extrahepatic blood supply in preoperative TACE of HCC.
