  2. Isotopes in medicine - Wikipedia

    en.wikipedia.org/wiki/Isotopes_in_medicine

    Radioactive isotopes are used in medicine for both treatment and diagnostic scans. 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 ...

  3. Nuclear medicine - Wikipedia

    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 ...

  4. Radioimmunoassay - Wikipedia

    en.wikipedia.org/wiki/Radioimmunoassay

    It requires special precautions and licensing, since radioactive substances are used. [citation needed] In contrast, an immunoradiometric assay (IRMA) is an immunoassay that uses radiolabeled molecules but in an immediate rather than stepwise way. A radioallergosorbent test (RAST) is an example of radioimmunoassay

  5. Technetium-99m - Wikipedia

    en.wikipedia.org/wiki/Technetium-99m

    Technetium-99m is used in 20 million diagnostic nuclear medical procedures every year. Approximately 85% of diagnostic imaging procedures in nuclear medicine use this isotope as radioactive tracer . Klaus Schwochau's book Technetium lists 31 radiopharmaceuticals based on 99m Tc for imaging and functional studies of the brain , myocardium ...

  6. Scintigraphy - Wikipedia

    en.wikipedia.org/wiki/Scintigraphy

    Scintigraphy (from Latin scintilla, "spark"), also known as a gamma scan, is a diagnostic test in nuclear medicine, where radioisotopes attached to drugs that travel to a specific organ or tissue (radiopharmaceuticals) are taken internally and the emitted gamma radiation is captured by gamma cameras, which are external detectors that form two-dimensional images [1] in a process similar to the ...

  7. Immunoassay - Wikipedia

    en.wikipedia.org/wiki/Immunoassay

    In 1983, Professor Anthony Campbell [4] at Cardiff University replaced radioactive iodine used in immunoassay with an acridinium ester that makes its own light: chemiluminescence. This type of immunoassay is now used in around 100 million clinical tests every year worldwide, enabling clinicians to measure a wide range of proteins, pathogens and ...

  8. Radiopharmacology - Wikipedia

    en.wikipedia.org/wiki/Radiopharmacology

    Radiopharmacology is radiochemistry applied to medicine and thus the pharmacology of radiopharmaceuticals (medicinal radiocompounds, that is, pharmaceutical drugs that are radioactive). Radiopharmaceuticals are used in the field of nuclear medicine as radioactive tracers in medical imaging and in therapy for many diseases (for example ...

  9. Radiopharmaceutical - Wikipedia

    en.wikipedia.org/wiki/Radiopharmaceutical

    125 I is a gamma emitter with a long half-life of 59.4 days (the longest of all radioiodines used in medicine). Iodine-123 is preferred for imaging, so I-125 is used diagnostically only when the test requires a longer period to prepare the radiopharmaceutical and trace it, such as a fibrinogen scan to diagnose clotting.
