Question

Quizplus · Accepted Answer

PET scans require the participant to ingest or inject small amounts of radioactive substances, such as glucose, to visualize areas of the body that absorb the substance and emit radiation. This radiation is then detected by a scanner to create an image of the body's physiological processes. PET scans do not expose the participant to X-rays, strong magnets, or require the wearing of a helmet with sensors.
