Positron Emission Tomography Positron emission tomography (PET) is a three-dimensional brain imaging technique that takes advantage of changes in metabolism to localize brain activity and functional processes in the body. The most active parts of the brain use more metabolic processes than do relatively inactive parts of the brain and PET is able to track this metabolic flow. Oxygen-15, the most common radioactive tracer isotope, is injected into the bloodstream where it disperses to more active parts of the brain. High Spatial resolution No temporal resolution Invasive. Injection of radioactive molecules
Functional Magnetic Resonance Imaging Like PET, Functional magnetic resonance imaging (fMRI)
