Biliary reflux detection in anomalous union of the pancreatico-biliary duct patients

Figure 1 A 52-year-old woman with anomalous union of the pancreatico-biliary duct and a type Ia choledochal cyst. A: Fusiform dilation of the common hepatic and cystic ducts with a focal stricture in the common bile duct (arrow) on T2-magnetic resonance cholangiography (MRC); B: Maximum intensity projection (MIP) reconstruction image of 60-min delayed gadoxetic acid-enhanced MRC shows the main pancreatic duct (arrowhead), indicating biliopancreatic reflux; C: MIP reconstruction image of 30-min delayed gadoxetic acid-enhanced MRC after a fatty meal shows progression of contrast media (arrowhead) along the main pancreatic duct; D: Gadoxetic acid-enhanced MRC coronal image taken 30 min after a fatty meal shows visualization of the main pancreatic duct (arrowhead) using contrast material.
