2. Radioactive iodine uptake test - Wikipedia

   en.wikipedia.org/wiki/Radioactive_iodine_uptake_test

   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 131 I iodide, or 3.7–7.4 MBq (100–200 μCi) of 123 I ...

   There are numerous approaches to treating hyperthyroidism, from taking anti-thyroid medications to undergoing radioactive iodine therapy. In extreme cases, surgery can be performed to remove part ...

4. Hyperthyroidism - Wikipedia

   en.wikipedia.org/wiki/Hyperthyroidism

   A radioactive iodine uptake test and thyroid scan together characterizes or enables radiologists and doctors to determine the cause of hyperthyroidism. The uptake test uses radioactive iodine injected or taken orally on an empty stomach to measure the amount of iodine absorbed by the thyroid gland.

5. Plummer effect - Wikipedia

   en.wikipedia.org/wiki/Plummer_effect

   Unlike the Wolff–Chaikoff effect, the Plummer effect does not prevent the thyroid from taking up radioactive iodine, e.g. in the case of nuclear emergencies.Therefore, "plummering" with high-dose iodine is only effective in a short time window after the release of radionuclides. [9]

6. Thyroid disease - Wikipedia

   en.wikipedia.org/wiki/Thyroid_disease

   Initial blood tests often include thyroid-stimulating hormone (TSH) and free thyroxine (T4). [9] Total and free triiodothyronine (T3) levels are less commonly used. [9] If autoimmune disease of the thyroid is suspected, blood tests looking for Anti-thyroid autoantibodies can also be obtained. Procedures such as ultrasound, biopsy and a ...

7. Jod-Basedow phenomenon - Wikipedia

   en.wikipedia.org/wiki/Jod-Basedow_phenomenon

   In some ways the Jod-Basedow phenomenon is the opposite of two physiological compensation mechanisms, the Plummer effect and the Wolff–Chaikoff effect, which in normal persons and in persons with thyroid disease, suppress the thyroid hormone after ingestion of large quantities of iodine or iodide. However, unlike the Plummer and Wolff ...

8. Thyrotoxic myopathy - Wikipedia

   en.wikipedia.org/wiki/Thyrotoxic_myopathy

   Administering the radioactive isotope causes the thyroid to take in the lethal iodine and quickly radiation destroys it. [12] Typically overproduction of thyroxine using radio-iodine is blocked with one dose. The drawback to this treatment is the thyroid gland is completely destroyed and patients often develop hypothyroidism. Some do so only a ...

9. Thyroid function tests - Wikipedia

   en.wikipedia.org/wiki/Thyroid_function_tests

   Thyroid function tests (TFTs) is a collective term for blood tests used to check the function of the thyroid. [1] TFTs may be requested if a patient is thought to suffer from hyperthyroidism (overactive thyroid) or hypothyroidism (underactive thyroid), or to monitor the effectiveness of either thyroid-suppression or hormone replacement therapy.
