Abstract

Objective To evaluate the value of portal vein image reconstruction techniques in diagnosis of portal vein diseases using 64-slice spiral CT.Methods Sixty cases of portal vein diseases were undergone portal vein image reconstruction with 64-slice spiral CT,including multiplanar reconstruction(MPR),maximum intensity projection(MIP) and volume rendering(VR).Results Among 60 cases,hepatic artery portal fistula 5 cases,portal vein embolism 41 cases,portal sponge degeneration 1 cases,8 cases collateral vessel with liver cirrhosis and portal hypertension,and the portal invasion by adjacent lesion 5 cases.MIP and VR clearly showed lesion in the main portal vein,portal branches vessles and the portal invasion by adjacent lesion;MPR directly showed the whole shape,the extent and lumen narrowing.Conclusion The portal vein image reconstruction technique is an effective method in diagnosis of portal vein diseases.
