Visualization of the gallbladder wall at excretory urography: implication for infusion tomography of the gallbladder

Visualization of the gallbladder wall during intravenous infusion of diatrizoate has been equated with cholecystopathy. However, a large control group of patients without biliary tract symptoms has not been studied. The authors examined a group of 2,867 such patients who underwent excretory urography; the results suggest that visualization of the normal gallbladder wall occurs frequently enough to severely limit the usefulness of infusion tomography of the gallbladder in the diagnosis of cholecystopathy.
