Fig. 1 Schematic drawings of the pancreaticobiliary duct system with periampullary carcinomas. Distal dilated pancreaticobiliary duct angle and the distance from the proximal end of the distal dilated pancreaticobiliary duct to the major papilla defined in our study were demonstrated.

Fig. 2 Pancreatic head carcinoma confirmed surgically in a 53-year-old man. (a) Coronary oblique image shows dilatation of the CBD (black arrow) and MPD (white arrow) distal to a heterogeneous mass (arrowhead) on true FISP sequence. (b) Coronary oblique contrast-enhanced image shows the dilated CBD (white arrow) and MPD (black arrow) distal to a poorly enhanced mass (arrowhead). (c) Coronary oblique contrast-enhanced image manifests the major duodenal papilla (white arrow).

Fig. 3 Intrapancreatic bile duct carcinoma of the periductal-infiltrating type in a 54-year-old man. (a) Coronary oblique image shows a markedly dilated CBD (black arrow). There is mild dilatation of the MPD (white arrow) is also seen. (b) Coronary oblique contrast-enhanced image shows the dilated CBD (white arrow) and MPD (black arrow). Enhancement of the thickened wall of the intrapancreatic bile duct is revealed (arrowhead). (c) Axial contrast-enhanced image manifests the major duodenal papilla (arrow).

Fig. 4 Ampullary carcinoma of the nodular mass type in a 65-year-old woman. (a) Coronary oblique image shows a nodular filling defect (arrowhead) at the distal end of the CBD on true FISP sequence. (b) Coronary oblique contrast-enhanced image shows an enhanced mass (arrowhead) protruding into the duodenal lumen.
