Chronic pancreatitis: Pain and computed tomography/magnetic resonance imaging findings

Table 2 Cambridge classification diagnostic criteria in chronic pancreatitis[27]

To evaluate chronic pancreatitis from the aspects of pancreatic parenchyma, pancreatic duct morphology, local changes, and so on by CT and US
Normal	Quality study visualising the whole gland without abnormal features
Equivocal	One sign only	Main duct enlarged (< 4 mm)
		Gland enlarged (up to 2 × normal)
		Cavities (< 10 mm)
		Irregular ducts
		Focal acute pancreatitis
		Parenchymal heterogeneity
Mild changes	Two or more signs	Duct wall echoes increased
Moderate changes		Irregular head/body contour
Marked changes	As above, and with one or more of: Large cavities (> 10 mm), gross gland enlargement (> 2 × normal), intraductal filling defects or calculi, duct obstruction, structure or gross irregularity, contiguous organ invasion

CT: Computed tomography; US: Ultrasound.
