For the early diagnosis of portal hypertension, the relationship between portal venous hemodynamic changes and degree of liver fibrosis was evaluated using abdominal 4D-flow MR imaging. Flow quantification was performed in the middle part of the portal trunk. The forward flow was significantly correlated with Fib-4 index. In the comparison between the three groups divided by the degree of fibrosis, only the average velocity was significantly different. As the liver fibrosis progressed, the forward flow of the portal vein increased. The average velocity of the portal vein may be useful for early diagnosis of liver fibrosis.
