radioiodine

[ra″de-o-i´o-dīn] any radioactive isotope of iodine; of the nine isotopes, iodine 123, iodine 125, and iodine 131 are the most commonly used in diagnosis and treatment of benign and malignant diseases of the thyroid gland and in scintiscans of organs such as the lung, liver, and kidney. Called also radioactive iodine.radioiodine uptake test one of the most common thyroid function tests; a known quantity of radioiodine is administered and 24 hours later the per cent is calculated that has been absorbed by the thyroid gland. Patients who have recently been exposed to iodine compounds, such as in dietary supplements, contrast media, medications, or antiseptics may not be good candidates for this test.

(rā'dē-ō-ī'ō-dīn), A radioactive isotope of iodine, for example, ¹²³I.

radioactive iodine

Any of the radionuclides of iodine, the most commonly used of which is beta- and gamma-emitting 131I, with a half-life of 8 days. It is used clinically as an implant for treating thyroid cancer and hyperactivity, and for scintigraphy of other organs. The gamma-emitting 125I has a half-life of 59.4 days and has been used in bioassays, nuclear medicine imaging and in radiation oncology as brachytherapy to treat prostate cancer and brain tumours.
