title: Reverse discordant behavior and progressive filling of a cold nodule on Tc-99m pertechnetate thyroid imaging.
abstract: The authors report on a patient with reverse discordant behavior between Tc-99m pertechnetate and I-131 associated with progressive filling of a cold nodule on the Tc-99m pertechnetate thyroid scan. Possible mechanisms are discussed.
