They are able to show how tissues in the brain are functioning and show areas which may be structurally abnormal, that do not show up on an MRI scan. In people with epilepsy it can be used to see if there is an obvious reason for their seizures. Brain imaging with MRI identifies structural cerebral pathology that may give rise to seizures. These waves may or may not show evidence of seizure activity. These pictures can show up any damage in your brain. Clinicians can find evidence of abnormal electrical activity in the brain and figure out the type or types of seizures a patient is having, as well as the origin(s), by measuring brain waves over minutes to a couple of hours.

Positive Emission Tomography (PET scan) PET scans are more precise than SPECT scans. The neurologist looks for spikes or sharp waves ("epilepsy waves") to confirm the diagnosis, but the absence of these abnormal brain waves does not mean you didn't have a seizure in the past. The greatest yield is from MRI at 3T using epilepsy protocols, and reported by expert neuroradiologists who possess the full clinical data. An MRI -- magnetic resonance imaging -- scan is a test that produces very clear pictures, or images, of the human body without the use of X-rays. MRI scans look at the structure and function of the person’s brain (how their brain is made up and how it works). Both of these procedures produce a picture of how the brain looks exactly. Futhermore, if surgery is considered as a treatment option, high resolution MRI in combination with EEG/MEG can lead to a more precise picture of where exactly in the brain the epilepsy focus is located (if there is one).
