The Full Story
Positron emission tomography for brain research developed in the 1970s, with early influential human studies appearing around 1975. PET allowed researchers to observe brain metabolism and later neurotransmitter activity using radioactive tracers. It was a major advance over purely structural imaging because it showed function as well as anatomy. PET still has an important role in neurology, oncology, and psychiatry.
