原发性胆汁性肝硬化与病毒肝炎性肝硬化影像学对比探讨

The imageology features of primary biliary cirrhosis （PBC） and viral hepatitis-related liver cirrhosis

目的 探讨原发性胆汁性肝硬化与病毒肝炎性肝硬化的影像学特征.方法 选择原发性胆汁性肝硬化（A组）患者与病毒性肝炎患者（B组）各40例,均采用多层螺旋CT检查,比较其影像学特点.结果 A组与B组各有9例（22.5％）和3例（7.5％）患者出现肝脏体积增大,差异无统计学意义（Х^2=3.53,P＞0.05）.A组肝脏增大患者左叶外侧段增大2例,弥漫性增大7例；B组3例均为左叶外侧段增大.A组与B组中分别有28例（70％）和8例（20％）合并胆囊炎,两组差异有统计学意义（Х^2=20.20,P＜0.05）.A组与B组合并胆囊结石者分别有13例（32.5％）和7例（17.5％）,两组差异有统计学意义（Х^2=2.40,P＞0.05）.结论 多层螺旋CT检查可用于辅助鉴别诊断原发性胆汁性肝硬化与病毒肝炎性肝硬化.

Objective To explore the imageology characters of primary biliary cirrhosis（PBC） and Viral hepatitis cirrhosis.Methods A total of 40 cases with PBC （group A） and 40 cases with viral hepatitis cirrhosis （group B） were included in our study.Spiral CT was conducted to every participants and the result in two groups were compared.Results The liver volume increased were found in 9 （22.5%） and 3 （7.5%） cases respectively in group A and B,but the difference has no statistical significance（Х^2 =3.53,P 〉 0.05）.The left lobe of outside part of liver increased were found in 2 cases and 3 cases in group A and B respectively,another 2 cases in group A showed hepatic diffusivity increased.Twenty-eight cases（70%） in group A and 8 cases（20%） in group B combined with cholecystitis.There is significant difference between them （Х^2 =20.20,P 〈 0.05）.About 13 （32.5 %） and 7 （17.5 %）cases combined with gallstone in group A and B and the difference has statistical significance（Х^2 =2.40,P 〉 0.05）.Conclusions Spiral CT can be used to diagnose PBC and viral hepatitis cirrhosis.
