摘　　要：目的:从核磁共振3D影像学角度探讨肝脏Ⅷ段门静脉的分布情况。方法:选取100例正常的健康体检肝脏影像资料进行核磁共振三维重建,采取2D和3D对应的方法,对肝脏Ⅷ段门静脉进行观察和分类。结果:100例正常活体肝移植供肝中,肝脏Ⅷ段门静脉可大致分为4种类型:单轴型、两支型、三支型、四支型,各占16.0%、72.0%、8.0%和4.0%。具有腹侧支和背侧支的共84%。背侧支都跨越了肝右静脉。结论:3D影像能够更好的直观反映肝脏Ⅷ段门静脉的立体空间分布情况,大多具有腹侧支和背侧支。Objective： To evaluate the distribution of the branches of the segment VIII by 3-D point of view. Methods： using 100 successive sections of the upper abdomen of adult MRI enhanced images of living donor for liver transplantation. We investigated the course and division pattern of the intrahepatic portal vein of segment VIII by 2D and 3D image and also the relationship between them. Results： Among the 100 cases, the branches of segment VIII may be divieded into four types： monopodium, two branches, three branches and four branches and the peccentage was 16%, 72%, 8% and 4% respectivly. About 84% has the ventral and dorsal branches and the dorsal branch across the right hepatic vein. Conclusion： 3D image can display a better impression of the distribution of the branches of the portal veins of the segment VIII and can provide informations for hepatic surgery .
