title: Expanded criteria for the ultrasonic diagnosis of gallstones.
abstract: The ultrasonic examination of the gallbladder for stones can be an accurate procedure if an expanded set of criteria are used. Employing such criteria we have been able to reach a diagnosis in 92 percent of examinations with no false positive and no false negative results. The expanded criteria are described and several illustrative examples are shown.
