"The chemistry of technetium allows it to be bound to a variety of biochemical compounds, each of which determines how it is metabolized and deposited in the body, and this single isotope can beused for a multitude of diagnostic tests. More than 50 common radiopharmaceuticals are based on technetium-99m for imaging and functional studies of the brain, heart muscle, thyroid, lungs, liver, gall bladder, kidneys, skeleton, blood, and tumors."
"Technetiumis a chemical element with the symbol Tc and atomic number43. It is the lightest element whose isotopes are all radioactive, none of which are stable other than the fully ionized state of 97Tc.[4] Nearly all available technetium is produced as a synthetic element. "
