PET scan (Positron Emission Tomography) is a neuroimaging technique that uses radioactive tracers to measure blood flow, metabolism, and brain activity. The tracer is injected into the bloodstream, and as it decays, it emits positrons that collide with electrons creating gamma rays which are detected by the scanner. This allows for a 3D image to be created showing areas of the brain that are active during a specific task or at rest.
