Accurate quantification of hepatic blood flow would facilitate improved understanding of the hemodynamic mechanisms by which portal hypertension affects the function of the liver. In this retrospective analysis, data acquired with an efficient 4D phase velocity imaging method was analyzed to assess flow to the hepatic vasculature. Data from 17 participants, 10 with portal hypertension and 7 controls were evaluated. Compared to healthy controls, patients with portal hypertension demonstrated increased blood flow through the portal vein.
