Diagnostic Value of Morphology on MRCP in Chronic Pancreatitis and Pancreatic Carcinoma / 实用放射学杂志

ABSTRACT

Objective To study the value of magnetic resonance cholangiopancreatography(MRCP) in diagnosing chronic pancreatitis(CP) and pancreatic cancer(PC).Methods MRCP findings in 31 cases of CP and 31 cases of PC were analyzed.Results MRCP characteristics in CP group included :(1) irregular dilatation of the pancreatic duct(87.1%),might across the whole segment of the lesion(93.5%);(2)dilatation of bile duct less(29%);tapering(48.4%) or normal(48.4%) or abrupt interruption(3.2%);(3)stones within the pancreatic duct(25.8%),pseudocyst(29%).MRCP characteristics in PC group included:(1)double-duct sign(67.7%);(2)continuous and smooth dilatation of the pancreatic duct distal to tumor(61.3%),abrupt interruption at the site of the tumor(74.2%);(3)more percentage of bile duct dilatation(74.2%),abrupt interruption of common bile duct at site of tumor(71%).Conclusion MRCP characteristics are of vital importance in differenntial diagnosing CP and PC.
