Technetium-99m (99m Tc) is a metastable nuclear isomer of technetium-99 (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.
The metastable technetium-99m (99m Tc) is a short-lived (half-life about 6 hours) nuclear isomer used in nuclear medicine, produced from molybdenum-99. It decays by isomeric transition to technetium-99, a desirable characteristic, since the very long half-life and type of decay of technetium-99 imposes little further radiation burden on the body.
Technetium (99m Tc) mertiatide is a radiopharmaceutical medication used in nuclear medicine to image the kidneys. [1] It is a renal imaging agent that is given by intravenous injection. [1] It was approved for medical use in the United States in June 1990. [2]
The vast majority of the technetium-99m used in medical work is produced by irradiating dedicated highly enriched uranium targets in a reactor, extracting molybdenum-99 from the targets in reprocessing facilities, [40] and recovering at the diagnostic center the technetium-99m produced upon decay of molybdenum-99.
Technetium 99m Tc albumin aggregated (99m Tc-MAA) is an injectable radiopharmaceutical used in nuclear medicine. It consists of a sterile aqueous suspension of Technetium-99m (99m Tc) labeled to human albumin aggregate particles. It is commonly used for lung perfusion scanning.
Technetium (99m Tc) sestamibi is a lipophilic cation which, when injected intravenously into a patient, distributes in the myocardium proportionally to the myocardial blood flow. Single photon emission computed tomography imaging of the heart is performed using a gamma camera to detect the gamma rays emitted by the technetium-99m as it decays.
Technetium (99m Tc) pentetic acid, sold under the brand name Draximage DTPA among others, is a radiopharmaceutical medication used in nuclear medicine to image the brain, kidneys, or lungs. [1] It is given by intravenous injection or via aerosol spray. [ 1 ]
Five modern technetium-99m generators The first technetium-99m generator, unshielded, 1958. A Tc-99m pertechnetate solution is being eluted from Mo-99 molybdate bound to a chromatographic substrate A technetium-99m generator , or colloquially a technetium cow or moly cow , is a device used to extract the metastable isotope 99m Tc of technetium ...
