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.
4 is the starting material for most of the chemistry of technetium. Pertechnetate salts are usually colorless. [4] TcO − 4 is produced by oxidizing technetium with nitric acid or with hydrogen peroxide. The pertechnetate anion is similar to the permanganate anion but is a weaker oxidizing agent. It is tetrahedral and diamagnetic.
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.
A technetium-99m pertechnetate scan, also called Meckel scan or nuclear scintigraphy scan, is the investigation of choice to diagnose Meckel's diverticula in children. This scan detects gastric mucosa ; since approximately 50% of symptomatic Meckel's diverticula have ectopic gastric or pancreatic cells contained within them, [ 24 ] this is ...
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 from a decaying sample 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.
Sodium pertechnetate is the inorganic compound with the formula NaTcO 4. This colourless salt contains the pertechnetate anion, TcO − 4 that has slightly distorted tetrahedron symmetry both at 296 K and at 100 K [ 2 ] while the coordination polyhedron of the sodium cation is different from typical for scheelite structure.
Pertechnetate is one of the most available forms of technetium. It is structurally related to permanganate. The most prevalent form of technetium that is easily accessible is sodium pertechnetate, Na[TcO 4]. The majority of this material is produced by radioactive decay from [99 MoO 4] 2−: [1] [2] [99 MoO 4] 2− → [99m TcO 4] − + e −
