Tc-99m is the preferred tracer for a number of scans used in medicine worldwide to help diagnose medical conditions. Tc-99m scans are used to detect a wide range of conditions including injuries, infections, tumours, heart disease, thyroid abnormalities, kidney conditions and also to guide some cancer procedures. 2 dagar sedan · Technetium-99m is a metastable nuclear isomer of technetium-99, symbolized as 99m Tc. The "m" indicates that this is a metastable nuclear isomer. It is a gamma ray emitting isotope used in radioactive isotope medical tests, for example as a radioactive tracer that medical equipment can detect in the body. 99m Tc-labeled Isoniazid and 99m Tc-Labeled Ethambutol 99m Tc-INH and 99m Tc-EMB has been successfully used for the diagnosis of sensitive as well as resistant tuberculosis in patients. These radiotracers are used to target Mycobacterium tuberculosis as these drugs interact specifically with mycolic acid, an important constituent of mycobacterial cell wall. 99m Tc is used in nuclear medicine for a wide variety of diagnostic tests and imaging studies, e.g., myocardial perfusion scans, bone scans, and V/Q scans..

Reduced 99m Tc + Chelating Agent -----> 99m Tc-Chelate The chelating agent usually donates an ion pair of electrons to form coordinate covalent bonds with 99m Tc Chelating molecules such as DTPA, macroaggregated albumin (MAA), gluceptate (GH), proteins, and enzymes contain electron donor groups such as - COO - , -OH - , -NH 2 and -SH 2018-02-08 · Tc-99m has been in use as a medical imaging diagnostic agent for decades and is used in more than 80 percent of nuclear medicine imaging procedures in the U.S. Before this recent FDA clearnance, molybdenum-99, or Mo-99, the parent of Tc-99m, could only be produced from enriched uranium by several facilities outside of the United States. Pertechnetate Tc 99m may affect fertility in males or females. Pregnancy Category C In animal reproductive studies, Sodium Pertechnetate Tc 99m (as free pertechnetate) has been shown to cross the placental barrier. It is not known whether Sodium Pertechnetate Tc 99m can cause fetal harm when administered to a pregnant woman or can affect Technetium Tc 99m Generator . FOR DIAGNOSTIC USE .
Technetium Tc99m Disofenin is rapidly cleared from the circulation of normal individuals following intravenous administration; about 8% of the injected activity remains in
Technetium-99m's short half-life of 6 hours makes long-term storage impossible. Transport of 99m Tc from the limited number of production sites to radiopharmacies (for manufacture of specific radiopharmaceuticals) and other end users would be complicated by the need to significantly overproduce in order to have sufficient remaining activity after long journeys. Technetium TC 99M Disofenin - Clinical Pharmacology Disofenin (Hepatolite) is an iminodiacetic acid derivative with no known pharmacologic actions at the doses recommended. Technetium Tc99m Disofenin is rapidly cleared from the circulation of normal individuals following intravenous administration; about 8% of the injected activity remains in
Tc-99m pertechnetate thyroid scan is a functional nuclear medicine study used to assess the thyroid gland.The uptake of the pertechnetate anion - similar in chemical-physical characteristics to the iodide ion - in the thyroid parenchyma is mediated by the NIS (Sodium-Iodide Symporter).

Technetium Tc 99m Sestamibi is a cationic Tc 99m complex which has been found to accumulate in viable myocardial tissue in a manner analogous to that of thallous chloride Tl-201. Scintigraphic images obtained in humans after the intravenous administration of the drug have been comparable to those obtained with thallous chloride Tl-201 in normal and abnormal myocardial tissue. 2020-08-19
Tc-99m MAA is enormous: the adverse reaction rate in the US for Tc-99m MAA is approximately 2/100,000 injections, an outstanding track record. This safety record is attributable to the very small fraction of the pulmonary vasculature that is occluded by the typical injection of Tc-MAA.
