Question

Quizplus · Accepted Answer

PET (Positron Emission Tomography) scans utilize detectors of radioactive tracers to measure metabolic activity in the body. The participant is injected with a small amount of a radioactive substance, which is detected by the PET scanner to create an image of the internal body functions. It does not expose the participant to x-rays or require them to wear a helmet containing sensors.
