Abstract:

Objective:To analyze variations of main trunk of portal vein (MTPV) in healthy persons by multislice spiral computed tomography portagraphy (MSCTP). Methods:Four hundreds and five subjects （including 200 normal volunteers）were performed by test bolus to demonstrate the optimization of MSCTP from December 2006 to June 2007 at the Affiliated Zhujiang Hospital of South Medical University.The maximum intensity prejection (MIP),volume rendering (VR) and multiplanar reformation (MPR) were employed for threedimensional reconstruction to analyze variations of MTPV (1～3 grades). Results:There were 12 types of MTPV (1～3 details) with the variation rate of 2074%. Conclusion:Due to high variation rate of portal vein among normal people,the 3-D reconstruction of multislice CT is constructive to local the focus and the decision of approaches for the surgical treatment in clinic.

Key words: portal vein variation, multislice spiral CT

摘要：

目的:分析肝内门静脉解剖变异，探讨64层螺旋CT门静脉成像技术（MSCTP)在临床中的应用。方法:对2006年12月至2007年6月南方医科大学附属珠江医院的405例（包括200名健康志愿者）检查者采用小剂量预注射技术（Test Bolus）行门静脉血管成像，最大强度投影(MIP)、容积再现(VR)及多平面重组（MPR）观察门静脉1～3级分支情况，并确定门静脉分支类型。结果:在405例成像中，门静脉1～3级分支共有12种变异类型，变异率为2074%。结论:肝内门静脉变异率较高，术前行多层螺旋CT门静脉血管三维重建对病灶定位及术式评估具有一定的临床意义。
