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。
Abstract
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.
