Patients with chronic liver diseases generally have
portal hypertension (PH) characterized by an increased
liver resistance to blood flow that mainly affect the
portal system. In order to determine the severity of PH
some invasive methods has been proposed. In this work we
present a method to indirect estimate the severity of PH
by the quantification of the intrahepatic portal vein
blood flow with a non-contrast, flow depend technique
(TIR-ASL).
