Abstract

Objective To evaluate the role of MRA,IPVG and DUS in the hemodynamics studies of portal hypertension.Methods Thirty-eight patients with portal hypertension were examined with Philips Gyroscan 1.0 Tesla MR imaging system.3D-DCE MRA and 2D-PC MR were used for study of portal venous anatomy and its hemodynamics.The results were compared with those obtained from IPVG and DUS.Results 3D-DCE MRA could clearly display the anatomical imaging of portal venous system and its imaging quality was better than that of IPVG.The data of hemodynamics from 2D-PC MR including diameter,blood velocity and blood flow were closely correlated to those from DUS.Conclusion As a non-invasive technique,MRA can display the anatomy of portal venous system and measure its hemodynamics exactly.It should be applied as the first choice in hemodynamics evaluation for portal hypertension.
