Iodine-131 (131 I, I-131) is an important radioisotope of iodine discovered by Glenn Seaborg and John Livingood in 1938 at the University of California, Berkeley. [3] It has a radioactive decay half-life of about eight days. It is associated with nuclear energy, medical diagnostic and treatment procedures, and natural gas production.
Radiation-induced thyroiditis is a form of painful, acute thyroiditis resulting from radioactive therapy to treat hyperthyroidism or from radiation to treat head and neck cancer or lymphoma. It affects 1% of those who have received radioactive iodine (I-131) therapy for Graves' Disease, typically presenting between 5 and 10 days after the ...
Hypothyroidism may be a complication of this therapy, but may be treated with thyroid hormones if it appears. The rationale for radioactive iodine is that it accumulates in the thyroid and irradiates the gland with its beta and gamma radiations, about 90% of the total radiation being emitted by the beta (electron) particles.
Her treatment involved destroying the portion of the thyroid that produces hormones via radioactive iodine, per the report. She would go on to train for the Olympics in Barcelona in 1992, where ...
Toxic multinodular goiter can be treated with antithyroid medications such as propylthiouracil or methimazole, radioactive iodine, or with surgery. [5] Another treatment option is injection of ethanol into the nodules. [9] A Cochrane review compared treatments using recombinant human thyrotropin-aided radioactive iodine to radioactive iodine ...
Radioactive material remaining on the skin or in the stomach should be removed. If radioiodine was inhaled or ingested, potassium iodide is recommended. Complications such as leukemia and other cancers among those who survive are managed as usual. Short-term outcomes depend on the dose exposure. [4]
The test was first introduced in 1956, using iodine-131 diodrast. [25] [26] Later developments included iodine-131, and then iodine-123, labelled ortho-Iodohippuric acid (OIH, marketed as Hippuran). [27] [28] 99m Tc-MAG3 has replaced 131 I-OIH because of better quality imaging regardless of the level of kidney function, [29] and lower radiation ...
Only the Wolff–Chaikoff effect is helpful to prevent the thyroid from uptaking radioactive iodine in the case of nuclear emergencies. Therefore, "plummering" with high-dose iodine is only effective in a short time window after the release of radionuclides. [15] Wrong timing of iodine use may even increase the risk by triggering the Plummer ...
