PET radiotracer

A PET radiotracer, or positron emission tomography radiotracer, is a type of radioactive compound used in medical imaging to visualize and measure metabolic processes in the body. These tracers are labeled with a positron-emitting radionuclide, which generates positrons that collide with electrons in the body, resulting in the emission of gamma rays. These gamma rays are detected by a PET scanner, allowing the creation of detailed images of internal organs and tissues.
