title: [Ultrasonography of the gallbladder and oral cholecystography. A prospective comparative study].
abstract: A prospective study comparing the information supplied by ultrasonography of the gallbladder and oral cholecystography was conducted in 254 patients with clinically suspected gallbladder calculi. The results demonstrated the limitations of cholecystography, notably the frequency of non-opacification in the absence of hepatic-biliary tract pathology and the possibility of false-negative results. Ultrasonography proved adequate in more than 80% of the cases and may be considered as the examination of choice for the diagnosis of biliary calculi. Its own limitations are discussed.
