摘　　要：目的评估改良肝尾叶与右叶比值(C/RL-r)在肝炎后肝硬化CT诊断中的价值。方法收集行CT扫描的肝炎后肝硬化病例120例(Child-Pugh分级:A级40例,B级46例,C级34例)和正常对照组120例,回顾分析其CT平扫及增强检查图像。由3名经验丰富的放射科医师测量计算改良肝尾叶与右叶比值,分别比较该比值在肝硬化组和正常对照组之间的总体差异及肝硬化Child-Pugh分级各组间的差异。结果肝硬化组改良尾叶与右叶比值(C/RL-r)大于对照组(P<0.05);肝硬化Child-Pugh各分级组间亦有差异(P<0.05),Child-Pugh B级组>C组和A组(P<0.05),Child-Pugh C组>A组(P<0.05)。结论 C/RL-r在肝炎后肝硬化CT诊断中具有重要价值,但与肝硬化严重程度并不完全一致。Objective To analyze the value of modified caudateright lobe with use of the right portal vein to set the lateral boundary in CT diagnosis of viral hepatitis cirrhosis and its correlation with Child-Pugh grading of liver cirrhosis. Methods One hundred patients with viral hepatitis cirrhosis, including 30 cases of Child Pugh A, 36 cases of Child Pugh B and 34 cases of Child Pugh C, and 100 normal controls were performed CT scan. Plain and enhanced CT images of 200 patients were retrospectively analyzed. Three experienced physicians measured C/RLr and compared the differences between the two groups and that of three Child Pugh staging groups. Results The C/R-r for the patients with cirrhosis of liver were higher than the control group （P＜0.05）. A difference in C/RL-r was found between the three Child Pugh staging groups （P﹤0.05）. The C/RLr for Child B patients was higher than that of Child A and Child C patients（P﹤0.05, P﹤0.05）. The C/RL-r for Child C patients was higher than that of Child A （P＜0.05）.Conclusion Modified caudate-right lobe ratio may has significant value for the CT diagnosis of viral hepatitis cirrhosis, but has no positive correlation with liver function ChildPugh classification.
