To assess hepatic blood flow (HBF) with a noninvasive method, we acquired HBF flow before and after meal ingestion using the pCASL method. In addition, we investigated the relationship of HBF, perfusion-related diffusion coefficient (D*) with intravoxel incoherent motion and portal vein blood flow (PVBF) with phase contrast. For each value of HBF, D*, and PVBF following meal ingestion increased significantly compared with the values prior to ingestion. However, there were no correlations between hepatic blood flow, perfusion-related diffusion coefficient, or portal flow with either pre- or post-ingestion.
