Figure 1. Detailed CT scan imaging characteristics of pancreatic enlargement and inflammation. (A, B) NECT axial images: Diffuse enlargement of the pancreas, especially of the head, with poorly-defined borders. Hyperdense content in the gallbladder. (C, D) CECT late arterial/portal venous phase; axial images: Heterogeneous attenuation of the head of the pancreas. Pancreatic inflammation is mainly localized to the area adjacent to the duodenum. Peripancreatic inflammation with surrounding fat stranding. (E, F) coronal and axial MPR images respectively: Pancreatic inflammation causing dilatation of the common bile duct and intrahepatic bile ducts. Arrows in the images point to the regions of inflammation and areas with ill-defined borders. NECT – non-enhanced computed tomography; CECT – contrast-enhanced computed tomography; MPR – multiplanar reconstruction.
