technetium-99m,

the radionuclide most commonly used to image the body in nuclear medicine scans. It is preferred because of its short half-life and because the emitted photon has an appropriate energy for normal imaging techniques. The "m" indicates that this radionuclide is metastable. It is generated on site from a molybdenum source.

technetium

a chemical element, atomic number 43, atomic weight 99, symbol Tc. See Table 6.

technetium-99m

the most frequently used radioisotope in nuclear medicine, a gamma emitter having a half-life of 6.04 hours and a primary photon energy of 140 keV; symbol ^99mTc.

^99m
