Abstract

BACKGROUND/AIMS: This study was performed to evaluate the diagnostic accuracy and clinical applications of magnetic resonance cholangiopancreatography (MRCP) compared with endoscopic retrograde cholangiopan creatography (ERCP).
METHODS
Prior to carrying out ERCP, MRCP was performed on 71 patients and the two examinations were compared using a double blank test.
RESULTS
The results revealed that 15 patients had choledocholithiasis, 4 gall bladder stones, 28 cholangiocarcinomas, 12 pancreatic head cancers, 2 ampulla of Vater cancers, 1 gall bladder cancer with ductal invasion, 4 other benign diseases and 5 normal conditions. For the patients with choledocholithiasis, the values of MRCP's sensitivity, specificity and accuracy were 100%, 98.2% and 98.6%, respectively, and those of ERCP's were all 100%. For the patients with malignant obstructions, the values of MRCP's sensitivity, specificity and accuracy were 90.7%, 100% and 94.4%, respectively, and the values of ERCP's were 95.3%, 92.9% and 94.4%.
CONCLUSIONS
These data show that MRCP has a rather high sensitivity, specificity and accuracy in the diagnosis of the biliary tract system, and therefore MRCP can be substituted for ERCP in the aspect of diagnosis.
