摘要

目的从计算机断层扫描（CT）和磁共振成像 (MRI)断面影像中获得肝脏标准解剖学体位的一些信息，用于对离体肝脏恢复其解剖位置。方法通过测量100例上腹部CT和MRI图像中下腔静脉与门静脉在横断面、矢状面和冠状面的相互角度来了解肝脏标准解剖体位的解剖学特征。包括横断面上，门静脉囊部到下腔静脉中心之间的连线与水平线（桌面）之间的角度；矢状面上，下腔静脉与桌面之间的角度；冠状面上，下腔静脉与体正中线之间的角度。从而获得关于肝脏标准解剖体位的三维数据。结果横断面上平均角度为左侧角(79.1±9.2)°；矢状面上平均角度为(7.3±5.1)°；冠状面上平均角度为(6.1±4.3)°。结论通过应用这些解剖学特征可以将离体的肝脏标本恢复到大致标准的解剖体位。为正确认识肝内结构相互关系奠定基础。

Abstract

Objective To provide the recovery of the anatomical position of the extracorporeal liver with the aid of measurements obtained from CT and MRI scans of the liver. Methods The correlation of the inferior vena cava (IVC) and portal vein were studied in the transverse, sagittal, and coronal planes of CT and MRI imaging of the liver in 100 patients.To obtained three-dimensional data of the anatomical position of the liver, three angles were determined and measured on three different scanning planes. There were the angle on the transverse plane between horizontal line(tabletop)and the line from the diverticular part of left portal vein to the centre of the IVC; the angle on the sagittal plane between the IVC and tabletop and the angle on the coronal plane between the IVC and middle line of body. Results On the transverse plane, the average left angle was (79.1±9.2)°, on the sagittal plane, the average angle was (7.3±5.1)°, and on the coronal plane, the average angle was (6.1±4.3)°. Conclusion By applying these measurements to the extracorporeal liver, and placing the liver at these angles, the anatomical position can be determined and restored.
