In a consecutive group of 1,067 noncholecystectomized patients referred for computed tomography including the upper abdomen, gallstones were seen in 13%. In 4% of the patients with gallstones, gas-containing calculi were found. On reviewing the conventional plain films such stones were revealed in less than one-half of the patients.
