MRCP images revealed dilatation of the common bile duct (CBD) and main pancreatic duct (MPD) (5\/14), dilatation of the MPD only (3\/14), dilatation of the CBD only (3\/14), and normal MPD and CBD (3\/14). Both FP and RP revealed three types of time\u2013signal intensity curves: 1) rapid rise to a peak, with a rapid decline (FP=2, RP=4), 2) slow rise to a peak, followed by a slow decline (FP=5, RP=4), and 3) slower rise to a peak, with a slow decline or plateau (FP=7, RP=6).
