【Abstract】ObjectiveTo evaluate the role of MRA, IPVG and DUS in the hemodynamics studies of portal hypertension.
MethodsThirty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.
Results3D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.
ConclusionAs 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.
