| technetium tc 99m pyrophosphate | <chemical> A radionuclide imaging agent used primarily in scintigraphy or tomography of the heart to evaluate the extent of the necrotic myocardial process. It has also been used in noninvasive tests for the distribution of organ involvement in different types of amyloidosis and for the evaluation of muscle necrosis in the extremities. Pharmacological action: radiopharmaceuticals, (12 Dec 1998) |
| technetium tc 99m sestamibi | <chemical> (oc-6-11)-hexakis(1-isocyano-2-methoxy-2-methylpropane)technetium(1+)-99mtc. A technetium imaging agent used to reveal blood-starved cardiac tissue during a heart attack. Pharmacological action: radiopharmaceuticals. Chemical name: Technetium(1+)-99Tc, hexakis(1-isocyano-2-methoxy-2-methylpropane)-, (OC-6-11)- (12 Dec 1998) |
| technetium tc 99m sulfur colloid | <chemical> A gamma-emitting radionuclide imaging agent used for the diagnosis of diseases in many tissues, particularly in the gastrointestinal system, liver, and spleen. Pharmacological action: radiopharmaceuticals. (12 Dec 1998) |
| technetium-99 | A radioisotope of technetium which is the decay product of technetium-99m and has a weak beta emission and a physical half-life of 213,000 years. (05 Mar 2000) |
| technetium-99m | A radioisotope of technetium which decays by isomeric transition, emitting an essentially monoenergetic gamma ray of 142 keV with a half-life of 6.01 hr. It is usually obtained from a radionuclide generator of molybdenum-99 and is used to prepare radiopharmaceuticals for scanning the brain, parotid, thyroid, lungs, blood pool, liver, heart, spleen, kidney, lacrimal drainage apparatus, bone, and bone marrow. 99mTc diphosphonate, a radionuclide complex used for bone scans. 99mTc-DPTA, a radionuclide chelate complex used for renal imaging and function testing. 99mTc sulfur colloid, a particulate radionuclide complex taken up by the reticuloendothelial system; used for imaging the liver and spleen.
