99mTc (Technetium-99m)

Technetium-99m (99mTc) is a radioactive isotope widely used in medical imaging to examine organs and tissues. It emits a short-lived gamma ray, which can be detected by special cameras, allowing doctors to visualize how various parts of the body function. Because its radioactivity is temporary, it provides detailed diagnostic information with minimal radiation exposure. 99mTc is produced from molybdenum generators and can be combined with different compounds to target specific organs, such as the heart or bones. Its reliable imaging ability makes it a vital tool in diagnosis and treatment planning.
