Radioactive isotopes are used to form images of the thyroid, bones, heart, liver, and many other organs. They used also have helped in treating diseased organs and tumors. The most commonly used example of such isotopes is technetium-99, which accounts for 80% of nuclear medicine procedures.he use of radioactive isotopes in medicine involves radionuclide therapy. Cancerous cells can be controlled or even eliminated by irradiating the tumor growth region. Teletherapy, also known as external irradiation is carried out by gamma beams emitted from radioactive cobalt-60 source.
Radionuclides used in PET scanning are isotopes with short halfâlives, such as carbon-11 (~20 min), nitrogen-13 (~10 min), oxygen-15 (~2 min) and fluorine-18 (~110 min). These radionuclides are added into compounds normally used by the body such as glucose (or variations of glucose), water or ammonia.Such labelled compounds are known as radiotracers. In some situations, the patient is required to breath oxygen gas labelled with oxygen-15.adioactive isotopes and radioactively labelled molecules are used as tracers to identify abnormal bodily processes. This is possible because some elements tend to concentrate (in compound form) in certain parts of the body â iodine in the thyroid, phosphorus in the bones and potassium in the muscles.
