Thyroid uptake/scan: Is a nuclear medicine test performed to evaluate the structure and function of the thyroid. Technetium 99m pertechnetate is a radioactive material that is taken up (like iodine) in the thyroid. The radiotracer is injected into the bloodstream and a detector is used to measure the uptake. A special camera is used to generate a picture of the thyroid to assess the structure. ...Read moreSee 2 more doctor answers
Is the radiation exposure from a study with dual injections of both iodinated-RISA and 99-m-technetium worth it? And the fact it's injected and present in blood over time worse than a single ct scan?
Minimal risk: The radio-emittance from these products are beta radiation which has minimal penetration and the products rapidly decay so the exposure to your body is trivial. You in fact get more dosage from a CT scan, but that is also not pathologic in one exposure. Hopefully your scans will guide you to better health. ...Read moreSee 1 more doctor answer
