• Technetium-99m (99mTc) is a metastable nuclear isomer of technetium-99 (itself an isotope of technetium), symbolized as 99mTc, that is used in tens of millions of medical diagnostic procedures annually, making it the most commonly used medical radioisotope in the world. (wikipedia.org)
  • 99mTc remained a scientific curiosity until the 1950s when Powell Richards realized the potential of technetium-99m as a medical radiotracer and promoted its use among the medical community. (wikipedia.org)
  • Radiopharmaceuticals for diagnostic use are classified in this group, while radiopharmaceuticals for therapeutic use are classified in V10. (whocc.no)
  • Therefore, products on the market, that can often be regarded as intermediate products rather than ready-to-use radiopharmaceuticals, can be given more than one (5th level) ATC code, e.g. technetium ( 99m Tc) exametazime (V09AA01) and technetium ( 99m Tc) exametazime labelled cells (V09HA02).
