Gallbladder stone shown on a hepatobiliary scan
Tomography, X-Ray Computed

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.
