Background/Aims: The aim of this study was to measure the apparent diffusion coefficient (ADC) values detected by diffusion-weighted imaging (DWI) in acute pancreatitis and compare them with computerized tomography (CT) findings in acute pancreatitis subgrouped by the Balthazar classification. Materials and Methods: The study population included 50 patients diagnosed with clinical pancreatitis who were evaluated with both multidetector CT and magnetic resonance imaging (MRI) within 24 h of clinical presentation. We calculated pancreatic ADC values obtained from DWI (b=0 and b=1000 mm
