What are the risks of a positron emission tomography (PET) scan?

ANSWER

A PET scan uses a small of amount of radioactive material to make an image of the inside of your body. There always is a small chance that it could damage cells or tissue. But radiation levels are usually very low. You also may find your arm a bit sore where the IV was put on your arm.
