During a PET scan, the patient is given a substance called a tracer, typically a chemical found in the body (oxygen, glucose, nitrogen, fluorine) which has been tagged with a radioactive atom that breaks down quickly to release positrons. However, as a PET involves radioactive material, it is not suitable for everyone. The image from the PET camera is based on the detection of radiation that is emitted from a radioactive tracer, which has been given to the patient as an intravenous injection. Candy, including chewing gum, cough drops, and mints. Radioactive tracers are also used to determine the location of fractures created by hydraulic fracturing in natural gas production.
