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.

We do not fallhöjd på 0,46 m (med en strömhastighet på 2,99 m/s vid ett utsläpp på cirka 7,42 m3/s).

Technetium Tc 99m decays by isomeric transition with a physical half-life of 6.02 hours. Blood clearance studies indicate that the fast clearing component clears with a t½ of 4.3 minutes at rest, and clears with a t½ of 1.6 minutes under exercise conditions. A relatively short physical half-life of six hours, and a biological half-life of one day, makes Tc-99m ideal for use in procedures such as single-photon emission computed tomography (SPECT). Importantly, soon after the procedure ends, no radioactivity is left in the body. a) Tc 99m decays by isomeric transition with a physical half-life of 6.02 hours. The principal photon that is useful for detection and imaging studies has a percent Technetium-99m is a short-lived form of Tc-99 that is used as a medical diagnostic tool.

Of the total technetium Tc 99m retained in the whole blood pool 24 hours (MRI). Tc-99m has a short physical half-life of 6 hours and a biological half-life of 1 day and is, therefore, quickly eliminated from the body. Tc-99m is a pure gamma-ray emitter that emits a 140 keV photon suitable for detection and allows for highly precise alignment of imaging detectors. Characteristics of Tc-99m make it ideal Technetium-99m. Atomic No. Radionuclide Class Table 1 Occupational Values Table 2 see 93m Tc-2E+5: 1E-4: 3E-7--Page Last Reviewed/Updated Thursday, March 25, 2021 Technetium (99m Tc) sestamibi (commonly sestamibi; USP: technetium Tc 99m sestamibi; trade name Cardiolite) is a pharmaceutical agent used in nuclear medicine imaging.The drug is a coordination complex consisting of the radioisotope technetium-99m bound to six (sesta=6) methoxyisobutylisonitrile (MIBI) ligands.

A relatively short physical half-life of six hours, and a biological half-life of one day, makes Tc-99m ideal for use in procedures such as single-photon emission computed tomography (SPECT). Importantly, soon after the procedure ends, no radioactivity is left in the body.

Se hela listan på rxlist.com Technetium Tc 99m decays by isomeric transition with a physical half-life of 6.02 hours. The principal photon that is useful for detection and imaging is listed in Table 1.

Technetium Tc-99m pertechnetate Accession Number DB09314 Description. Technetium Tc-99m pertechnetate is a radiopharmaceutical diagnostic agent composed of an oxoanion with the chemical formula TcO4-. Pertechnetate has a wide variety of uses within nuclear medicine as it distributes within the body to a similar extent as iodine.

Technetium TC-99m is one of the radioactive isotopes of technetium, a gamma/beta-emitter with a half life of 6 hours.
