We have previously validated MRI as a surrogate measure of Hepatic Venous Pressure Gradient (HVPG) at 1.5T using T1 relaxation time and splanchnic haemodynamics. Here, we explore the use of quantitative 3T MRI to assess portal hypertension. A strong correlation between HVPG and fat suppressed IR SE-EPI T1 (p<0.0001) and a correlation with superior mesenteric artery (SMA) velocity (p=0.02) was observed. MOLLI T1 showed a weak correlation with HVPG (p=0.11) compared with SE-EPI (p<0.001) in a matched patient subset. A fat suppressed IR SE-EPI T1 scheme and SMA velocity can be used as a surrogate for HVPG at 3T.
