  2. Sestamibi parathyroid scan - Wikipedia

    en.wikipedia.org/wiki/Sestamibi_parathyroid_scan

    A nuclear medicine parathyroid scan demonstrates a parathyroid adenoma adjacent to the left inferior pole of the thyroid gland. The above study was performed with Technetium-Sestamibi (1st column) and Iodine-123 (2nd column) simultaneous imaging and the subtraction technique (3rd column).

  3. 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 ...

    en.wikipedia.org/wiki/Nuclear_medicine

    Nuclear medicine (nuclear radiology, nucleology), [1] [2] is a medical specialty involving the application of radioactive substances in the diagnosis and treatment of disease. Nuclear imaging is, in a sense, radiology done inside out , because it records radiation emitted from within the body rather than radiation that is transmitted through ...

    But the procedure dragged on. When the surgeon updated Dorio nine hours later, the news was grim. The tumor had spread through the thyroid gland, onto the carotid artery and into the tracheal rings.

  6. Iodine-125 - Wikipedia

    en.wikipedia.org/wiki/Iodine-125

    Iodine-125 can be used in scanning/imaging the thyroid, but iodine-123 is preferred for this purpose, due to better radiation penetration and shorter half-life (13 hours). 125 I is useful for glomerular filtration rate (GFR) testing in the diagnosis or monitoring of patients with kidney disease .

  7. Iodine-123 - Wikipedia

    en.wikipedia.org/wiki/Iodine-123

    Iodine-123 (123 I) is a radioactive isotope of iodine used in nuclear medicine imaging, including single-photon emission computed tomography (SPECT) or SPECT/CT exams. The isotope's half-life is 13.2232 hours; [1] the decay by electron capture to tellurium-123 emits gamma radiation with a predominant energy of 159 keV (this is the gamma primarily used for imaging).

  8. Isotopes in medicine - Wikipedia

    en.wikipedia.org/wiki/Isotopes_in_medicine

    The most common isotope used in diagnostic scans is Technetium-99m, used in approximately 85% of all nuclear medicine diagnostic scans worldwide. It is used for diagnoses involving a large range of body parts and diseases such as cancers and neurological problems. [1]

  9. Radionuclide therapy - Wikipedia

    en.wikipedia.org/wiki/Radionuclide_therapy

    The iodide ion is selectively taken up by the thyroid gland. Both benign conditions like thyrotoxicosis and certain malignant conditions like papillary thyroid cancer can be treated with the radiation emitted by radioiodine. [6] Iodine-131 produces beta and gamma radiation. The beta radiation released damages both normal thyroid tissue and any ...
