title: The value of radionuclide scintigraphy in patients with non-visualized gallbladders by oral cholecystography.
abstract: This study evaluated the clinical usefulness of Tc-99m-PyG cholescintigraphy in patients who had nonvisualization of the gallbladder after OCG. Nineteen patients with non-visualized gallbladder with OCG subsequently had Tc-99m-PyG cholescintigraphy performed. In nine patients the gallbladder visualized, whereas in ten it did not. Statistical analysis of this limited number of patients showed that Tc-99m-PyG cholescintigraphy was able to separate those patients with clinically significant gallbladder disease from those patients without significant gallbladder disease (p less than 0.05).
