title: Gallbladder stone shown on a hepatobiliary scan.
abstract: Hepatobiliary scans are performed frequently to identify gallbladder-related disease. Although gallbladder stones are a common cause of hepatobiliary disease, they are visualized directly only rarely on hepatobiliary scans. Large gallbladder stones produced a photopenic defect in the gallbladder in a hepatobiliary scan.
