Quantitative MRI to Assess Portal Pressure in Patients With Liver Disease: Validation at 3 T
Hepatic venous pressure gradient (HVPG) is the gold standard for assessing portal hypertension (PH). We previously demonstrated that a bivariate MRI model combining liver T1 and splenic artery velocity at 1.5 T correlates with HVPG. This study aimed to evaluate this model at 3 T and investigate additional splanchnic MR...
