Characteristics of three dimensional reconstruction of the portal vein systems of patients with portal hypertension / 中华消化外科杂志

ABSTRACT

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 diagnosis and treatment of hepatobiliary diseases.In order to study the characteristics of the 3 D model of portal branches and collateral circulation in various types of portal hypertension,the data of 64-slice spiral CT scan of5 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.
