Technetium-99 - an overview ScienceDirect Topics
Web99m Tc is a very versatile radioisotope, and is the most commonly used radioisotope tracer in medicine. It is easy to produce in a technetium-99m generator, by decay of 99 Mo . 99 Mo → 99m Tc + e− + ν e The molybdenum isotope has a half-life of approximately 66 hours (2.75 days), so the generator has a useful life of about two weeks. In brain scanning, 99m Tc is attached to the chelating agent HMPAO to create technetium (99m Tc) exametazime, an agent which localizes in the brain according to region blood flow, making it useful for the detection of stroke and dementing illnesses that decrease regional brain flow and metabolism.
