Overview
MRI
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'.
Patient #1
MRI demonstrates superior mesenteric vein thrombosis secondary to chronic pancreatitis:
