Magnetic resonance diagnosis of chronic pancreatitis / 基础医学与临床

ABSTRACT

Objective To evaluate the accuracy of MRI diagnosis and the clinical value of multi-MR imaging techniques.Methods Clinical,pathologic and MRI findings were retrospectively reviewed in 25 cases with chronic pancreatitis.The MRI manifestation included pancreatic morphology and volume change,signal feature,dynamic contrast-enhanced MRI and MRCP.The MRI techniques included both before and after Gd-DTPA enhancement FS FLASH T1WI,FLASH TIWI,HASTE T2WI and MRCP.Results The characteristic signs in diagnosis of chronic pancreatitis were as follows diffuse enlargement of the body;hypointense on T1WI FS;dynamic contrast-enhanced MRI,lesion and normal area always enhanced at the same time;pancreatic duct dilated like a string of beads which penetrated into the lesion shown by MRCP.Conclusion MRI can detect chronic pancreatitis earlier than CT,and it can display pancreatic duct and pseudo-cysts so is of great value in the diagnoses of chronic pancreatitis.
