Quizplus · Accepted Answer

PET scans involve injecting a small amount of radioactive substance into the body, which gets absorbed by the brain cells. The emitted radiation is detected by the PET scanner and used to create a 3D image of the brain, showing differences in activity in specific areas. TAT and EEG measure psychological functioning, while CT shows structural abnormalities but does not reveal activity differences.
