Abstract

Positron emission tomography (PET), when coupled with molecularly targeted positron emitter labeled organic compounds or labeled drugs, enables the measurement of biochemical transformations and the movement of drugs directly into the human brain and other organs. PET is the only imaging technology that can image and quantify specific cellular elements as well as the distribution and movement of drugs in the living human brain. This chapter introduces PET technology and radiotracer chemistry, which has enabled the visualization and quantification of the chemical anatomy of the human brain (as well as that of other organs) while working within the time constraints imposed by short-lived isotopes. It concludes with examples of PET studies in major brain diseases and in drug development as well as an outlook for the future of PET technologies in the neurosciences including its value for understanding the role of genes in brain diseases.
