To evaluate the ability of magnetic resonance angiographic inflow-sensitive inversion recovery (IFIR-MRA) to assess hemodynamics of portal vein system in patients with portal hypertension, we compared visualized portal vein branching grade scores at different blood suppression inversion time (BSP TI) settings and signal intensity contrast ratio of the vessles and the liver parenchyma with color Doppler ultrasonograghy (CDUS) measured hemodynamics. Statistically significantly correlation demonstrated that IFIR-MRA of portal vein system has the potential to suggest hemodynamic changes, especially for RPV.
