摘　　要：目的:探讨64层螺旋CT门静脉造影重建技术对门静脉病变中的诊断价值。方法:对70例门静脉系统疾病患者行MSCT门静脉造影,重建技术有多平面重建(MPR)、最大密度投影(MIP)和容积再现(VR)。结果:肝动脉—门静脉瘘5例,门静脉栓塞41例,门静脉海绵样变5例,肝硬化门静脉高压侧枝循环形成8例,良性病、恶性病变门静脉受压改变16例。多层螺旋CT血管重建技术MIP及各种角度及厚度的VR能清楚显示门脉主干的病变,邻近肿瘤对门脉的侵犯和门脉的侧支血管;MPR较直观地显示了病变整体形态、范围及门静脉管腔变窄程度。结论:MSCT门静脉造影重建技术是显示门静脉病变的有效诊断方法。Objective：To evaluate the diagnosis value of portal vein angiography reconstruction in portal vein diseases using 64-slice spiral CT.Methods：70 cases of portal vein diseases were underwent poi＇tal vein reconstruction with 64-slice spiral CT, including multiplanar reconstruction （MPR）, maximum intensity projection （MIP） and volume rendering （VR）.Results：5 cases hepatic artery portal fistula. Portal vein thrombus 41cases.Portal sponge degeneration 5 cases.8 cases the collateral circulation of portal hypertension in liver cirrhosis. 16 cases portal vein compression by benign and malignant diseases. MIP and VR can clearly show lesion in the main portal vein, the portal invation by adjacent tumor and portal vein branches; MPR can directly show the whole shape, of the extent and narrowing lumen.Conclusion ：The portal vein angiography reconstruction is an effect diagnostic method for portal vein diseases.
