肝硬化肝脏及门静脉CT解剖学及其临床意义

To Study Liver and Portal Vein's CT Anatomy of Cirrhosis and Its Clinical Significance

目的 通过对肝硬化肝脏各叶及门静脉进行量化研究 ,为临床影像早期诊断肝硬化提供依据。方法 选择肝硬化代偿期组、失代偿期组作为疾病组 ,选择健康人作为对照组进行对比研究 ,利用人体常用解剖轴线作为肝脏测量的基准线。门静脉系统的测量采用文献报道的常用方法。结果 肝硬化时肝脏左叶冠状径 (L1 )的变化最具临床意义 ,肝硬化代偿期时该值增大 ,肝硬化失代偿期时该值缩小 :肝叶比例不仅存在于肝叶间同时也存在于肝叶内。门静脉管径的变化主要发生于肝硬化代偿期 ,通过建立门静脉的变化与肝脏变化的数学模型对早期肝硬化进行预测。结论 可以利用肝脏各叶的测量值及门静脉管径的变化预测和诊断早期肝硬化。

Objective The research is about the liver and portal vein' s quantity measurement on the cross section of CT imaging At same time,the data pot in use clinical diagnosis.Methods To select the compensatory phase cirrhosis group, the lose compensatory phase group as researching groups,and normal body's cross section CT imaging as comparing group,and to select lines which often use in the anatomy as measuring criterion lines;the measurement of portal vein system adopt the report's methods.Results When liver took place cirrhosis, the left lobe of cirrhosis's coronal diameter(L 1) have main meaning,increasing in the compensatory phase cirrhosis and decreasing in the lose compensatory phase cirrhosis.Not only have the maladjustment of liver lobes ratio of cirrhosis taken place among liver lobes,but also within every liver lobe.The diameters of portal cirrhosis vein have main statistics meaning between the compensatory cirrhosis group and normal comparing group.In order to connect liver with portal vein, we use classify analysis to put up mathematical model Conclusion We may use dates of the lobes of liver and portal vein systam to predict or diagnose early cirrhosis and improve sensibility.
