Quizplus · Accepted Answer

PET scans utilize detectors of radioactive tracers to measure the metabolic activity of cells in the body. The radioactive tracers are injected into the body and emit gamma rays, which are detected by the PET scanner to create an image of the activity in the body. PET scans do not expose the participant to X-rays or strong magnets, and do not require the participant to wear a helmet containing sensors.
