Any radioactive isotope of iodine, especially iodine-131; used as a tracer to determine the activity and size of the thyroid gland, and experimentally, to destroy the thyroid glands of animals.

Thyroid cancer patients undergoing post-operative radioiodine therapy are administered the radioactive iodine (in a single dose, capsule form) in a specially constructed, lead-lined inpatient room at the hospital, and are isolated for the three to five-day period which the therapy takes to complete; treatment and patient care is provided by a specially trained team and all patient contact for care givers and family members/visitors is carefully controlled to minimise any risk of contamination by keeping the time of visits short, maintaining distance from the patient and using radiation shielding devices.
Thyro-Cat Centers treat feline hyperthyroidism with RadioIodine therapy, and are fully licensed by the State Departments of Health and the Nuclear Regulatory Commission.
In these studies, nearly all patients received radioiodine, and many also underwent adjuvant therapy including surgical excision of metastatic bone lesions, external radiotherapy, arterial embolization or chemotherapy (10), (11).
CONCLUSION: Our findings suggest that childhood radioiodine exposure from nuclear testing may be related to subsequent adult infertility.
In most cases it is detected incidentally on radioiodine scanning, or it presents with dysphagia or airway compromise in infancy or childhood.
west coast from minuscule levels of radioiodine coming from Japan.
Exclusion criteria: (i) Scintigraphic diagnosis of subacute viral thyroiditis, (ii) pregnant women and those breastfeeding who could not wean off baby for eight weeks post-treatment with radioiodine, (iii) patients with free T4 levels > 5 ng/ml at the time of treatment were excluded as [sup.
1,4,5) It is believed that in patients with toxic nodular goiters, the radioiodine uptake is restricted primarily to the hyperfunctioning autonomous areas within the gland as opposed to uniform distribution of radioiodine uptake in Graves' disease, hence conferring a relative protection against hypothyroidism.
Endocrinologists, pharmacologists, surgeons, and other medical specialists from around the world also discuss differential diagnosis, Graves' disease, styles of coping with stress and patients' disease acceptance level, radioiodine treatment, orbital decompression in patients with severe thyroid ophthalmopathy, the effectiveness of adrenergic blockers on hyperthyroidism associated insulin resistance, acute thyroid emergencies, thyroid receptor antagonists, thyroid carcinoma, autoimmune thyroid diseases, unusual presentations, and thyroid function in infants with mothers with Graves' disease and hyperthyroidism during pregnancy.
1) Traditionally, ultrasonography and radioiodine scintigraphy have been the imaging modalities most commonly used to visualize thyroid cancer.
It is likely that radioiodine while in systemic circulation may cause some adverse effects on antioxidative enzymes present in red blood cells (RBCs).
