WebThe iodine is taken up by the thyroid gland and a gamma camera is used to obtain functional images of the thyroid for diagnosis. Quantitative measurements of the thyroid … WebIodine is lost from the thyroid in the form of organic iodine. This organic iodine uniformly distributes among all organs & tissues of the body, other than the thyroid, and is retained with a biological half-life of 12 days. 90% of the organic iodine lost from the thyroid is returned to the transfer compartment and the rest is excreted via
