Core Tip
Core tip: Hepatic abnormal perfusion (HAP) due to acute pancreatitis on enhanced magnetic resonance imaging (MRI) presents as a strip-shaped abnormality of the hepatic tissue adjacent to the gallbladder or a patch- or wedge-shaped abnormality with lobar distribution in the liver, which is most likely caused by both the inflamed gallbladder and acute pancreatitis. Indications of HAP resulting from acute pancreatitis should not be misinterpreted as primary liver abnormalities. The presence of HAP on MRI cannot be used to indicate the severity of acute pancreatitis.
