The Use of <sup>99m</sup>Tc-Methoxy-isobutyl-isonitrile (sestaMIBI) Uptake on Scintigraphy (<sup>99m</sup>-STS) in Amiodarone-Induced Thyrotoxicosis: Case Series and Review of the Literature

<div>The <sup>99m</sup>-STS with a dose of 21.8 mCi showed intense initial uptake of the tracer activity within the thyroid parenchyma followed by a near complete washout in the 3-hour delayed images suggestive of AIT-1. In addition, there is diffuse enlargement of the thyroid gland (left more than right) and physiologic pattern of tracer distribution observed in the nasopharyngeal mucosa, salivary glands, and imaged parts of the liver and myocardium. A photopenic area in the left chest region correlates with the pacemaker. (a) 10 min postinjection; (b) 3 hr postinjection.</div>
