摘要
目的：为ＭＲ矢状图像精确定位肝内占位性病变提供断层解剖学依据。方法：对照观察３８例腹部连续矢状断层标本、４１例胎肝管道铸型和８例活体腹部ＭＲ矢状图像，探讨肝段在矢状断面上的划分。结果：依肝左静脉可区分段Ⅱ和段Ⅲ，门静脉左支矢状部是段Ⅱ、段Ⅲ与段Ⅳ间的天然良界，段Ⅰ位于静脉韧带裂后方或／和下腔静脉前方，肝中静脉与肝门或胆囊窝的连线可用以区分段Ⅳ与段Ⅴ、段Ⅷ，依肝右静脉、胆囊窝和门静脉右支及其分支可区分出段Ⅴ、段Ⅷ、段Ⅵ、段Ⅶ。结论：依肝静脉、门静脉和肝的自然沟裂。
Objective:To provide the sectional anatomic data for sagittal MRI localizing the focal liver space occupying lesionsMethods:The division of the hepatic segments on the sagittal section was studied using MRI of 8 normal volunteers correlated with serial sagittal sections of 38 adult cadavers and 41 fetal liver corrosion castsResults:Segment Ⅱ is separated form segment Ⅲ by the left hepatic veinThe sagittal portion of the left portal vein is a natural limit in dividing segments Ⅱ,Ⅲ from ⅣSegment Ⅰ is posterior to the fissure for ligamentum venosum or/and anterior to the inferior vena cavaThe line through the middle hepatic vein and porta hepatis or fossa for gallbladder can be used to separate segments Ⅳ form Ⅴ,ⅦConclusions:The hepatic segments can be divided accurately on the sagittal MRI according to the hepatic and portal veins and natural fissures of the liver
