When a whole pet scan is taken can they see the brain?

Depends: A pet scan may be obtained from the skull base (lower head, just above spine) to the thigh or from the top of the head to the feet. If obtained from the top of the head, the entire brain would be included and brain metabolic activity can be evaluated. If the pet study is performed in conjunction with a ct (pet/ct), the brain tissue on ct can also be seen.

PET scan: If a whole body pet scan is done the brain is normally included.

If it is included: The drug given goes everywhere in the body, including the brain. How much of the body that is imaged depends on the disease being looked for. For lymphoma, scans start at the base of the brain and end at the upper thighs. For head and neck cancer, the scan is from the top of the head to the upper thighs. Melanoma includes the whole body, and seizures is just of the brain.
