PET
Positron Emission Tomography (PET) is a medical imaging technique that uses radioactive tracers to visualize metabolic processes in the body. In PET, a small amount of a radioactive substance, called a radiotracer, is injected into the body. The radiotracer travels to the target tissue or organ and emits positrons, which interact with electrons in the body to produce gamma rays. These gamma rays are detected by a PET scanner, which creates a 3D image of the distribution of the radiotracer in the body. PET is commonly used in oncology to detect and stage cancer, as well as in neurology to study brain function and diagnose neurological disorders.
