title: [Three-dimensional reconstruction and anatomic variation of the portal vein based on 64-slice spiral CT data].
abstract: OBJECTIVE
  To investigate the three-dimensional reconstruction methods of the portal vein using 64-slice spiral CT data and the anatomical variation of the portal vein.
  
  
  METHODS
  Three-dimensional reconstruction of the portal vein was performed using Mimics software based on the 64-slice spiral CT data of 64 cases. Each model of the portal vein and its branches was evaluated according to the presentation rate, depiction quality and anatomic variation.
  
  
  RESULTS
  The reconstructed model showed a depiction rates of 100% for the 4-grade branches of the portal vein. The stem of the portal vein and the left and right branches of the level III or above were all displayed, but in 2 cases the superior mesenteric vein and in 1 case the spleen vein was displayed only to the level IV. Of the 64 cases, 50 (78.1%) had normal portal vein and 14 (21.9%) showed anatomical variations.
  
  
  CONCLUSIONS
  The 3D model vividly mimics the anatomic variations of the portal vein to provide valuable information for surgical plans.
