PurposeThis study aims to compare assessment of cystic duct patency between gadoxetate disodium MRI and hepatobiliary scintigraphy.Materials and methodsWe performed a prospective study of patients who underwent gadoxetate disodium MRI within 16 h of scintigraphy.ResultsThe gallbladder filled on MRI and scintigraphy in 8 patients, none with acute cholecystitis. The mean time to gallbladder filling was 14.6 and 18.9 min for MRI and scintigraphy, respectively. The gallbladder did not fill on both MRI and scintigraphy in 3 patients, all of whom had acute cholecystitis.ConclusionEvaluation of cystic duct patency using gadoxetate disodium MRI is comparable to hepatobiliary scintigraphy.
