The purpose of our prospective study was to correlate the hepatic vasculature hemodynamic parameters measured with navigator-gated 4D flow MRI with the hepatic venous pressure gradient (HVPG) in patients with chronic liver disease and suspicion of portal hypertension (PH). Peak velocity in the celiac trunk (CT) was moderately correlated with HVPG, and was significantly elevated in patients with PH. CT flow was significantly elevated in patients with clinically significant PH (CSPH), while portal vein peak velocity was significantly reduced in patients with cirrhosis. Our results suggest that 4D flow MRI may be sensitive to hemodynamic changes in patients with PH.
