Features of CP seen by MRI/MRCP with or without secretin.

MRI and MRCP Features of CP
Main pancreatic duct and side branches	Strictures Ductal filling defects Ectatic side branches Ductal contour irregularity Disconnected/disrupted main pancreatic duct Congenital anomalies (e.g., pancreas divisum)
Parenchyma	Atrophy Steatosis
Fluid collections	Walled off necrosis vs pseudocyst
Secretin MRCP specific findings	Increase in diameter of main pancreatic duct Decreased duodenal filling by the pancreatic juice
T1 signal change	Decrease T1 signal in pre-contrast phase
Biliary system	Dilatation/strictures
Duodenum	Obstruction/stricture
