title: Thyroid scintigraphy of hyperthyroxinemia.
abstract: The term "hyperthyroxinemia" encompasses clinical syndromes associated with elevated levels of thyroid hormone in the presence of increased, normal, or decreased thyroid function. The clinical presentation (i.e., history and physical examination), in vitro thyroid function tests, as well as radioisotope thyroid imaging all play key roles in the diagnosis of the underlying thyroid disorder. Many of these disorders and their appearance on thyroid scintigraphy are presented in this atlas.
