| Comment | Positron emission tomography (PET) is a functional imaging technique that uses radioactive substances known as radiotracers to visualize and measure changes in metabolic processes, and in other physiological activities including blood flow, regional chemical composition, and absorption. Different tracers are used for various imaging purposes, depending on the target process within the body. Radionuclides used in PET scanning are typically isotopes with short half-lives such as carbon-11 (20 min), nitrogen-13 (10 min), oxygen-15 (2 min), fluorine-18 (110 min), gallium-68 (~67 min), zirconium-89 (78.41 hours), or rubidium-82(1.27 min). These radionuclides are incorporated either into compounds |
