A method of cholecystography applicable to small laboratory animals.
A method of intraperitoneal cholecystography is described and was tested on mice with experimentally induced gallstones. The presence of stones in the gallbladder was predicted with an accuracy of 95.5%, using doses of 3 ml of 51.6% meglumine iodipamide (Cholografin) per kg diluted 10-fold, followed a few days later by a repeat dose of 5 ml per kg in cases of nonvisualization of the gallbladder. Pilot studies on guinea pigs and rabbits suggest that this method is applicable to these animals too, although a higher dose of contrast medium is required.
