Thyroid Uptake Studies with I131 in Very Small Doses

The radioactive iodine uptake test is a type of scan used in the diagnosis of thyroid problems, particularly hyperthyroidism. It is entirely different from radioactive iodine therapy (RAI therapy), which uses much higher doses to destroy cancerous cells. The RAIU test is also used as a follow up to RAI therapy to verify that no thyroid cells survived, which could still be cancerous. WebUptake of radioiodide, like that of the normal isotope ( 127 I), is stimulated by TSH from the adenohypophysis, and there is no discrimination among the various radioiodide isotopes in the formation of organically bound iodide associated with thyroid hormone synthesis.
