摘要
随着现代影像技术的发展，基于CT或MRI检查原始数据的各种三维重建技术已逐渐应用于肝、胆、胰、脾疾病的临床诊断和治疗，但主要是针对肝脏肿瘤的术前评估。目前对于门静脉高压症患者的门静脉系统主干主要采用CT或MRI三维重建，
With the development of modern imaging technologies, three-dimensional （3D） reconstruction techniques based on the computed tomography （CT） or magnetic resonance imaging （MRI） data has been gradually applied in clinical diag- nosis and treatment of hepatobiliary diseases. In order to study the characteristics of the 3D model of portal branches and collat- eral circulation in various types of portal hypertension, the data of 64-slice spiral CT scan of 5 patients with portal hypertension were collected and imported to the abdominal medical image three-dimensional visualization system （MI-3DVS） for sequence segmenting and 3D reconstruction, and then the results of 3D models were compared with operation findings. The 3D models were vividly, visually and clearly displayed the portal system and the collateral circulation, which is helpful in the diagnosis and treatment of the portal hypertension.
