Positron emission tomography (PET) is a powerful in vivo imaging technique capable of providing dynamic information on biochemical processes in the living human subject. Applications of PET in oncology, neurology, psychiatry, cardiology and other medical specialties continue to grow. The use of PET relies on the characteristics and availability of appropriately labeled radiopharmaceuticals. Carbon-11 is one of the most useful radionuclides for PET chemistry, since its introduction into a biologically active molecule dose not modify the biochemical properties of the compound. [11C]Carbon dioxide (11CO2), produced by cyclotron, is the most common and versatile primary labeling precursor in the production of 11C–labeled radiopharmaceuticals.
