title: An evaluation of plain roentgenograms prior to oral cholecystography in children.
abstract: Plain roentgenograms were taken prior to oral cholecystography in 100 children. Three children had their gallstones obscured by the oral cholecystographic agent. Consideration should be given to obtaining plain roentgenograms in children with a strong clinical suspicion of gallbladder disease and a normal oral cholecystogram.
