Paper Summary:
This paper explores the chemical structure and clinical uses of technetium-based radio-pharmaceuticals which have since the 1970s, served as the mainstay for every hospital's nuclear medicine department. Today, fully 85% of all diagnostic scans in American hospitals use 99mTc in some chemical form. It includes a brief overview of several "technetium-essential" and "technetium-tagged" radio-pharmaceuticals, as well as a discussion of current areas of research and development for new technetium drugs.
From the Paper:
"Technetium-99m has several physical properties that make it ideal for use in nuclear medicine. Foremost among these is that Tc-99m generally emits only gamma rays. These gamma ray photons are of a high enough energy (140,000 eV) that they can easily pass through dense tissue and exit the body, but can be effectively stopped and detected by a special gamma camera. Other radionuclides generate alpha and/or beta particles, which are diagnostically useless since they lack the penetrating ability to exit the human body. Worse, the ionizing ability of these decay products can damage tissue."
