摘要
目的 探讨正常人肝尾状叶大小变化的规律及其与肝硬化患者之间的关系。资料与方法经临床资料、CT及B超证实的30例肝硬化患者和30例正常人肝脏分别行正中矢状面、斜矢状面、垂直斜矢状面CT重组,计算重组后各矢状面的有效层数及肝尾状叶长径及短径的值,比较正常人与肝硬化患者肝尾状叶的关系。结果 肝尾状叶正常组与肝硬化组各矢状面有效层数差异均有统计学意义(P值<0.001);正常组与肝硬化组各有效层面上尾状叶长径与短径比较均有显著统计学差异,且以正中矢状面短径之间(P=0.001)和斜矢状面短径之间最可靠(P<0.001),灵敏度分别为73.33%(22/30)、76.67%(23/30),特异度分别为73.33%(22/30)、80.00%(24/30)。结论 对肝尾状叶正中矢状面、斜矢状面和垂直斜矢状面有效层数、长径与短径的测量能为临床诊断肝硬化提供有利证据。
Objective To investigate the relationship between the size of caudate lobe and hepatic cirrhosis.Materials and Methods Thirty patients with hepatic cirrhosis confirmed by clinical data and 30 healthy subjects performed CT and ultrasound examinations.The CT data were reconstructed to meso-sagittal plane,oblique-sagittal plane and vertical-sagittal plane.Number of plane,the major and minor diameter of caudate lobe were calculated and measured on those planes.Results Between the patients with hepatic cirrhosis and healthy subjects,the number of utility plane on sagittal planes had statistical difference（P0.001）;the major diameter and minor diameter of caudate lobe on sagittal plane had statistical difference too,especially on mesosagittal plane（P=0.001）and oblique-sagittal plane（P0.001）with sensitivity of 73.33%（22/30）and 76.67%（23/30）,specificity of 73.33%（22/30）and 80.00%（24/30）respectively.Conclu-sion The parameters of plane numbers major and minor diameter of caudate lobe on meso-sagittal plane,oblique-sagittal plane and vertical-sagittal plane can provide imformation for clinical diagnosis of hepatic cirrhosis.
