On average, one in every two Australians can expect, at some stage in their life, to undergo a nuclear medicine procedure that uses a radioisotope for diagnostic or therapeutic purposes. How are radioactive isotopes used in medicine? For PET imaging, the imaging agent 2-deoxy-2-[ 18 F]fluoro-glucose with a half-life of approximately two hours is the primary radiotracer used in nuclear medicine procedures. Tritium is also of potential use in thermo-nuclear process. Radioactive iodine can be used to image the thyroid gland for diagnostic purposes. A tracer A substance that can be used to follow the pathway of that substance through a structure. The most common radioisotope used in diagnosis is technetium-99, with some 30 million procedures per year, accounting for 80% of all nuclear medicine procedures worldwide. Examples of Radioisotopes in Biology. Others, however, are unstable, making these atoms radioactive. Nuclear Medicine: Nuclear medicine is a branch of medicine and medical imaging that uses radioisotopes in its diagnosis and treatment of diseases. Stable Isotopes In Nutritional Studies are very useful tools which are used extensively in scientific research. They are used to measure engine wear, analyze the geological formation around oil wells, and much more. Carbon-11, Nitrogen-13, Oxygen-15, Fluorine-18: These are positron emitters used in PET for studying brain physiology and pathology, in particular for localising epileptic focus, and in dementia, psychiatry and neuropharmacology studies. This thereby minimizes unwanted side effects and damage to noninvolved organs or nearby structures. Examples of stable elements used in nuclear medicine isotopes such as carbon-13, nitrogen-15 and oxygen-18 as well as noble gas isotopes. Nuclear medicine is a medical specialty that uses radioactive tracers (radiopharmaceuticals) to assess bodily functions and to diagnose and treat disease. Radioactive isotopes are effective tracers because their radioactivity is easy to detect. Stable isotopes already play an important role in research today and will become even more important to research in the future. All other iodine radioisotopes have half-lives less than 60 days, and four of these are used as tracers and therapeutic agents in medicine. There are thousands of radioactive isotopes, but only around 20 are used the medicine. In nuclear medicine, short-lived isotopes are used as radioactive tracers that patients receive orally via inhalation or injection. medicine procedures per year.1 Sterilization of medical products • Today, over half of all medical equipment used in modern hospitals is sterilized using radiation. Isotopes are used in nuclear medicine because they can be inserted into tracer molecules that accumulate in specific organs and help to diagnose disease. These are some of the examples of radioactive isotopes used in diagnosing and treating elements. Radioactive isotopes have many convenient uses in the following fields: medicine, industrial (plastic, metal, oil), and in research. Radioactive isotopes and enriched stable isotopes are used widely in medicine, agriculture, industry, and science, where their application allows us to perform many tasks more accurately, more simply, less expensively, and more quickly than would otherwise be possible. 155Tb and 152Tb emit gamma rays detectable by gamma cameras or PET scanners. These include many types of cancers, heart disease, and other abnormalities within the body. The tracers emit gamma rays from a target area in a patient's body, allowing specialized machines to produce images for review by a physician. Other useful isotopes are cesium-137, which is used in cancer treatment. Agriculture: Radioactive isotopes are used in the agricultural industry as tracers in plants. Atoms of unstable isotopes – radioisotopes – change into other elements over time through radioactive decay. Radioactive isotopes have many useful applications in a wide variety of situations, for example, they can be used within a plant or animal to follow the movement of certain chemicals. Radioactivity. Iodine 123 (not 131 as this emits beta radiation which is less preferable) is used in tracing to investigate issues with thyroid function. Radioactive isotopes are effective tracers because their radioactivity is easy to detect. So in conclusion, isotopes are useful in medicine for supplying radiation and helping to both diagnose, and … Bones, the heart, the brain, the liver, the lungs, and many other organs can be imaged in similar ways by using the appropriate radioactive isotope. The most common, stable form of iodine has an atomic number of 53 (protons) and an atomic weight of 127 (53 protons plus 74 neutrons).
