MRCP had a specificity of 92 percent for choledocholithiasis. If a patient does not have choledocholithiasis, MRCP is 92 percent correct. It has an 87 percent sensitivity for choledocholithiasis. If a patient has choledocholithiasis, it will be correct 87 percent of the time. This is from five studies results pooled together.

From a retrospective study: "392 patients had a normal MRCP of which 71 underwent an ERCP investigation demonstrating a CBD stone in 29 patients. A normal MRCP was found to have a 93% negative predictive value (NPV) and 89% probability of having no CBD stone demonstrated as well as no readmission due to gallstone disease within six months following MRCP." ...Read more | Value of MRCP
78 patients with biliary pancreatitis underwent MRCP. The sensitivity of MRCP in detecting CBD stones was 93.3%. "In 38 patients who underwent ERCP, the sensitivity and negative predictive value of MRCP in detecting CBD stones were both 100% regardless of the dilatation of the bile duct (≥7 mm versus < 7 mm)." ...Read more | Diagnostic Value of MRCP
