PET scan (Positron Emission Tomography) is a type of imaging that involves injecting a patient with a radioactive substance that is processed by the brain. The radioactive substance emits positrons that can be detected by the scanner to show which parts of the brain are active. This makes it a useful tool for studying brain function and connectivity. MRI and CT scans are imaging techniques that provide detailed structural information about the brain, but do not show activity levels. EEG (Electroencephalography) measures electrical activity in the brain, but does not provide a detailed image of brain structure or activity.
