Evaluation of Magnetic Resonance Cholangiography in the Management of Bile Duct Stones

Abstract
PROCEDURES FOR diagnosing common bile duct stones (CBDSs) include intraoperative cholangiography (IOC),1 endosonography,1 and endoscopic retrograde cholangiography (ERC)—the most widely used of these 3 techniques2,3 because it offers the opportunity to provide therapy on determination of the diagnosis, with only a single invasive intervention.4 Intraoperative cholangiography is still considered by some as the criterion standard for diagnosis of CBDSs.1 However, ERC and IOC are associated with a relatively high incidence of negative diagnoses if used routinely on an unselected population.5,6
