Normal anatomy on MRCP. The confluence of the right and left intrahepatic ducts to form the common hepatic duct is seen (long thin arrow). The cystic duct (*) typically joins the right side of the common hepatic duct to form the common bile duct (CBD) (short arrow). The main pancreatic duct (arrowheads) drains along with the CBD into the major duodenal papilla. An accessory pancreatic duct is present (black circle), draining into the minor duodenal papilla. Fluid containing structures such as the gallbladder (GB), duodenum (D) and stomach (S) are well seen on this T2-weighted sequence with the duodenum obscuring part of the biliary tree
