A positron emission tomography (PET) scan is a type of nuclear imaging test that shows the metabolic activities (energy usage) of your brain. While X-ray, CT, and MRI scans look at the anatomy of your brain, a PET scan can give your doctor information about how your brain is working.
Overview. A positron emission tomography scan is an imaging test that uses nuclear medicine to view the body on a cellular level. The PET scan measures body functions, such as blood flow, metabolism and oxygen use, and may be used to detect disease, like cancer, and heart and brain problems. There are different types of PET scans. You may need to follow a low-carbohydrate diet 12 hours prior to a PET scan.
