Bacground/aims: Magnetic resonance cholangiopancreaticography is a noninvasive technique in examination of the biliopancreatic tract which requires less experience than endoscopic retrograde cholangiopancreaticography. The aim of this study was to evaluate the diagnostic value of magnetic resonance cholangiopancreaticography compared to endoscopic retrograde cholangiopancreaticography for common bile duct stones. Methods: The study included 27 patients (16 male, 11 female), with a median age of 59.2±8.1 years (range 24 to 76 years) who underwent magnetic resonance cholangiopancreaticography and then endoscopic retrograde cholangiopancreaticography and in whom the results of both techniques were compared. The time interval between each technique was no longer than 12 hours. Results: False negative results with magnetic resonance cholangiopancreaticography occurred in two cases with stones less than 3 mm in diameter. No false positivity was seen. Magnetic resonance cholangiopancreaticography was unsuccessful in detecting a stone in the common bile duct of a patient with massive ascites, while it had a sensitivity and specificity of 88.8% and 100% respectively. Conclusion: Magnetic resonance cholangiopancreaticography has very high sensitivity and specificity in the evaluation of the common bile duct and can avoid to perform purely diagnostic than endoscopic retrograde cholangiopancreaticography.
