Core tip: Contrast-enhanced computed tomography is widely used imaging modality for the diagnosis and staging of acute pancreatitis due to its excellent capacity to demonstrate early inflammatory changes as well as local complications including fluid collections, However, magnetic resonance imaging may be a better imaging technique due to its, nonionizing nature, higher soft tissue contrast resolution, better safety profile of intravascular contrast media, noninvasive evaluation of pancreatic duct integrity and also has superiority in discrimination of internal consistency of pancreatic collections which is useful in further management plan. Role of endoscopic ultrasound and other newer techniques is still in evolving phase.
