What is a positron emission tomography (PET) scan?

ANSWER

A PET scan is used to find the part of the brain that’s causing seizures. The test gives doctors information about how the cells in the body are working. A small amount of radioactive material called a tracer is injected in a person’s vein. The tracer sets off an interaction that allows the PET scanner to make an image of the brain’s use of oxygen or sugar (glucose).
