Abstract

Due to high iodine loading from iodinated contrast media, the thyroid uptake of common radiopharmaceuticals ([Tc]NaTcO and [I]NaI) can be influenced up to 2 mo after administration. In such cases, and generally when differential diagnosis between productive and destructive thyrotoxicosis is necessary, [Tc]Tc-sestamibi scintigraphy could be an option. This case highlights the role of [Tc]Tc-sestamibi in the evaluation of thyrotoxicosis in a patient with a blocked thyroid gland as a result of stable iodine saturation.

摘要

由于碘造影剂的高碘负荷，放射性药物（[Tc]NaTcO 和 [I]NaI）的甲状腺摄取在给药后长达 2 个月可能会受到影响。在这种情况下，通常在需要区分毒性弥漫性甲状腺肿和破坏性甲状腺毒症时，[Tc]Tc-甲氧基异丁基异腈闪烁扫描术可能是一种选择。本病例突出了[Tc]Tc-甲氧基异丁基异腈闪烁扫描术在评估因碘稳定饱和而导致甲状腺功能减退的患者的甲状腺毒症中的作用。
