Real‐time and conventional articulated‐arm gray‐scale static‐mode scanning were performed on 100 patients in a prospective study to determine the complementary or duplicative roles of these two ultrasound modalities in the confirmation of clinically suspected cholelithiasis. Twenty‐five abnormal findings were documented ultrasonographically, including 21 cases of cholelithiasis (12 confirmed by oral cholecystography and/or surgery), two cases of biliary sludge, one case of a gallbladder polyp, and one case of a probable blood clot. There was no instance of gallbladder lumen nonvisualization. Except in one case (that of a 420‐pound patient), real‐time ultrasonography documented all the gallbladder abnormalities shown by the articulated‐arm static scans. In two cases, one corroborated by oral cholecystography, cholelithiasis was documented by real‐time and not by static‐mode ultrasonography. In most cases, real‐time ultrasonography can be used to document the presence of cholelithiasis and obviate the need for conventional articulated‐arm static‐mode scanning.
