Risks
By Mayo Clinic staffAlthough a radioactive substance is used during a PET scan, the amount of radiation that you're exposed to is too low to affect the normal processes of your body.
However, this radioactive material might harm the fetus of a pregnant woman or the infant of a woman who is breast-feeding. You and your doctor can discuss risk to the fetus or infant versus the reasoning and benefit of having a PET scan performed.
