Technetium 99m

At the time the article was last revised Raymond Chieng had no financial relationships to ineligible companies to disclose, technetium 99m. Technetium agents based on the technetiumm Tcm technetium 99m are frequently used agents in medical imaging. A radiopharmaceutical labeled with Tcm constitutes a co-ordination complex in which ligands bond to a central atom of Tcm by co-ordinate covalent bonds 4. The radioactive technetium radiotracer can be chelated to a number of different compounds to create specific radiopharmaceuticals and optimize the functional imaging of various structures:.

Technetium Tcm is an isotope commonly used in a number of medical diagnostic imaging scans. Tc99m is used as a radioactive tracer for nuclear medicine; which is a form of medical imaging that assesses how particular parts of our body are working or functioning. Doctors or trained nuclear medicine health professionals will administer Tcm radiotracers to patients before a diagnostic test, usually by injection, to help diagnose medical conditions. As the half-life of Tcm is only six hours, it does not stay in the human body long. Nuclear medicine scans are safe and are a widely used imaging test. This shortage is affecting all medical facilities public and private in Australia, and it is unclear how long it will last. ANSTO are undertaking measures to source supplies from overseas to supplement limited resources in Australia.

Technetium chemical symbol Tc is a silver-gray, radioactive metal. It occurs naturally in very small amounts in the earth's crust, but is primarily man-made. Technetium is produced during nuclear reactor operation, and is a byproduct of nuclear weapons explosions. Technetium can be found as a component of nuclear waste. Technetiumm is a short-lived form of Tc that is used as a medical diagnostic tool. It has a short half-life 6 hours and does not remain in the body or the environment for long. Beta Particles. Air, sea water, soils, plants and animals contain very low concentrations of Tc Because of its long half-life, Tc remains in the environment for an extended period of time. Organic matter in soils and sediments slow the transport of Tc

Technetiumm 99m Tc is a metastable nuclear isomer of technetium itself an isotope of technetium , symbolized as 99m Tc, that is used in tens of millions of medical diagnostic procedures annually, making it the most commonly used medical radioisotope in the world. Technetiumm is used as a radioactive tracer and can be detected in the body by medical equipment gamma cameras. It is well suited to the role, because it emits readily detectable gamma rays with a photon energy of keV these 8. The relatively "short" physical half-life of the isotope and its biological half-life of 1 day in terms of human activity and metabolism allows for scanning procedures which collect data rapidly but keep total patient radiation exposure low. The same characteristics make the isotope unsuitable for therapeutic use. Technetiumm was discovered as a product of cyclotron bombardment of molybdenum. This procedure produced molybdenum , a radionuclide with a longer half-life 2.

Monitoring Technetiumm Tc99m can be administered both in adults and children. This is directly suitable for medical applications only in bone scans it is taken up by osteoblasts and some thyroid scans it is taken up in place of iodine by normal thyroid tissues.

Depending on the time required to process the target material and recovery of 99m Tc, the amount of 99m Tc relative to 99g Tc will continue to decrease, in turn reducing the specific activity of 99m Tc available. Two replacement Canadian reactors see MAPLE Reactor constructed in the s were closed before beginning operation, for safety reasons. Download as PDF Printable version. April The handling of technetiumm should only be done by trained healthcare professionals who are licensed and authorized to use radioactive agents.

Technetium 99 Tc is an isotope of technetium which decays with a half-life of , years to stable ruthenium , emitting beta particles , but no gamma rays. It is the most significant long-lived fission product of uranium fission, producing the largest fraction of the total long-lived radiation emissions of nuclear waste.
