Indications
Millicurie amounts of
131I ( Iodotope I-131) are used for
thyroid ablation in the management of hyperthyroidism.
131I is taken up and trapped in the same manner
as I
-.The ablative effect is exerted primarily through β-
particle emissions, which destroy thyroid tissue.The major
disadvantage associated with this therapy is the development
of hypothyroidism after thyroid ablation.
Microcurie amounts of radioiodine also are used for the
diagnostic evaluation of thyroid function.
