A positron emission tomography (PET) scanner is a specialized medical imaging device used to examine the internal function and metabolic activities of the body. It detects positron-emitting radioactive substances that are either naturally occurring or introduced into the body. By capturing images of the radiation emitted from these substances, a PET scanner provides valuable information for diagnosing and monitoring various medical conditions.
