title: Identification and differentiation of congenital gallbladder abnormality by quantitative technetium-99m IDA cholescintigraphy.
abstract: Failure to visualize the gallbladder in its usual location along the right inferior hepatic border suggests many possibilities including acute cholecystitis. The case described here reveals the importance of proper protocol for hepatobiliary imaging with 99mTC-IDA agents, the necessity of quantification of function as an integral part of imaging to enable proper differential diagnosis. A case of bilobed gallbladder presenting as a Valentine heart in an unusual location in the liver is described. The measurement of the CCK-8 induced gallbladder ejection fraction for each lobe facilitated proper diagnosis.
