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.

Oct 22, 2020 · Technetium-99m (99mTc) is an FDA-approved radionuclide agent for diagnostic imaging across various human organs, encompassing critical areas such as the brain, lungs, heart, and more. Following systemic administration, …

Mar 15, 2025 · Technetium agents based on the technetium-99m (Tc-99m) radioisotope are frequently used agents in medical imaging. A radiopharmaceutical labeled with Tc-99m constitutes a co-ordination complex in which ligands bond to a central atom of Tc-99m by co-ordinate covalent bonds 4 .

Feb 6, 2025 · Technetium-99 (chemical symbol Tc-99) is a silver-gray, radioactive metal. It occurs naturally in very small amounts in the earth's crust, but is primarily man-made. Technetium-99m is a short-lived form of Tc-99 that is used as a medical diagnostic tool.

Technetium-99m pertechnetate (99mTc04) is obtained directly from the "molly" generator using saline as the eluting solution. This radiopharmaceutical is used for brain, thyroid, salivary gland, and stomach scanning. Typical adult dose is 15 millicuries.

Sep 18, 2024 · Technetium TC 99M Sestamibi package insert / prescribing information for healthcare professionals. Includes: indications, dosage, adverse reactions and pharmacology.

Feb 1, 2025 · Technetium Tc 99m sulfur colloid injection is used to find lymph node tumors in patients with breast cancer. It also helps your doctor see an image of your liver, spleen, bone marrow, or a peritoneo-venous (LeVeen) shunt, to see how well they are working.

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.

The decay product of Mo-99, Tc-99m, is the workhorse isotope in nuclear medicine for diagnostic imaging. Tc-99m is used for the detection of disease and for the study of organ structure and function.

Nov 20, 2024 · Technetium-99m (99mTc) is a radionuclide isotope used primarily for diagnostic purposes in nuclear imaging. Technetium-99m was isolated in 1938 from molybdenum-99 (Mo-99) decay. In 1960 Richards was the first to suggest using technetium as a medical tracer.
