Visualization of the left hepatic lobe during radioisotopic venography/lung imaging with technetium-99m MAA.

An unusual case of uptake of radioisotope by the liver during radioisotope venography/lung imaging with Tc-99m MAA is presented. Abnormalities in venous circulation of the lower extremities and abdomen, perfusion of the lung, and structure of the liver were detected, and correlated with other studies performed on a single patient. The mechanisms of uptake of Tc-99m MAA by the liver are discussed, with special attention paid to the mechanism believed to be present in this case.
