Overview

Overview

MRI findings for chronic pancreatitis may be classified as early and late findings. Early findings may include low-signal-intensity pancreas on T1-weighted fat-suppressed images, decreased and delayed enhancement after IV contrast administration and dilated side branches. Late findings may include parenchymal atrophy or enlargement, pseudocyst formation, dilatation and beading of the pancreatic duct with intraductal calcifications giving an appearance of ‘chain of lakes’.

MRI

  • MRI may be helpful in the diagnosis of a rare form, groove pancreatitis.[1][2]

1. Morphological findings:

Features of chronic pancreatitis can be divided into early and late findings:[3][4][5][6]

(a) Early findings:

  • Low-signal-intensity pancreas on T1-weighted fat-suppressed images
  • Decreased and delayed enhancement after IV contrast administration
  • Dilated side branches ​

(b) Late findings:

  • Parenchymal atrophy or enlargement
  • Pseudocyst formation
  • Dilatation and beading of the pancreatic duct with intraductal calcifications can give an appearance of ‘chain of lakes’.
