Figure 1a. Patient 5. Images in a 35-year-old woman with chronic pancreatitis. (a) ERCP image shows subtle dilatation of the terminal ends of the secondary branches (open arrow) and a mild stricture in the pancreatic body (arrow). (b) Corresponding MRCP image demonstrates incomplete visualization (arrows) of the PD (detection). On the basis of this study, it also would be unclear if the nonvisualized segments are normal or have a stricture (characterization).

Figure 2a. Patient 13. Images in a 50-year-old man with a clinical diagnosis of chronic pancreatitis and biopsy-proved carcinoma in the pancreatic head. (a) ERCP image shows a narrowed distal common bile duct (arrow) and PD (arrowhead) with proximal dilatation (double duct sign). (b) Corresponding MRCP image demonstrates a very similar appearance.

Figure 3a. Patient 15. Images in a 31-year-old woman with pancreas divisum and persistent abdominal pain. (a) At ERCP, only the major papilla could be cannulated, and the ventral duct (open arrow) appears normal. (b) Corresponding MRCP image demonstrates a mildly irregular and dilated dorsal PD (arrows). Findings were proved at surgery.
