Discordant hepatic uptake of Tc-99m NGA and Tc-99m PMT in a patient with hepatoma

Clin Nucl Med. 1992 Oct;17(10):793-6. doi: 10.1097/00003072-199210000-00006.

Abstract

The authors report discordant hepatic uptake of Tc-99m NGA and Tc-99m PMT in a patient with hepatoma. Tc-99m PMT uptake was delayed and Tc-99m NGA concentrated in another area, thereby demonstrating that the uptake mechanisms for Tc-99m NGA and Tc-99m PMT are different. Tc-99m NGA imaging may be useful in characterizing the focal hepatic lesion of Tc-99m IDA or Tc-99m PMT concentration.
