Liver MRI was conducted with both 4D-Flow and APTw imaging before and after a meal challenge. After the meal, significantly increased blood flow velocity and volume were observed in portal vein (PV) and superior mesenteric vein (SMV) and significantly decreased blood flow was observed in splenic vein (PV), while no change was observed in APT values (MTRasym) in liver parenchyma after the meal.
