How do I prepare for a positron emission tomography (PET) scan?
A PET scan is used to find the part of the brain that’s causing seizures. Tell your doctor if you’re pregnant or may be pregnant, since the PET scan can harm your baby. Also tell your doctor if you’re taking any medications or supplements.
Depending on which part of your body is being tested, you may be asked to take off all your clothes and put on a hospital gown. You’ll also need to remove any dentures, jewelry, or metal objects, which may affect the reading.
