1. raiu

   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.The patient swallows a radioisotope of iodine in the form of capsule or fluid, and the absorption (uptake) of this radiotracer by the thyroid is studied after 4–6 hours and after 24 hours with the aid of a scintillation counter. The dose is typically 0.15–0.37 MBq (4–10 μCi) of 131I iodide, or 3.7–7.4 MBq (100–200 μCi) of 123I iodide. The RAIU test is a reliable measurement when using a dedicated probe with a reproducibility of 1 percent and a 95%-least-significant-change of 3 percent.The normal uptake is between 15 and 25 percent, but this may be forced down if, in the meantime, the patient has eaten foods high in iodine, such as dairy products and seafood. Low uptake suggests thyroiditis, high uptake suggests Graves' disease, and unevenness in uptake suggests the presence of a nodule.123I has a shorter half-life than 131I (a half day vs. 8.1 days), so use of 123I exposes the body to less radiation, at the expense of less time to evaluate delayed scan images. Furthermore, 123I emits gamma radiation, while 131I emits gamma and beta radiation.

1. raiu

   RAIU, or Radioactive Iodine Uptake, is a test used in nuclear medicine to measure the functionality of the thyroid gland. It involves the administration of a small amount of radioactive iodine, allowing practitioners to assess how well the thyroid absorbs iodine for the production of thyroid hormones. This test aids in diagnosing certain thyroid diseases, including Graves' disease, hyperthyroidism, and thyroid cancer.
