Abstract: Single photon emission computed tomography (SPECT) and positron emission tomography (PET) offer valuable information for the diagnosis, management, and follow up of patients with seizure disorders. These imaging studies can also contribute to the understanding of the pathophysiology of epilepsy. Intractable epilepsy in children is a serious disorder that has an overwhelming effect on physical, psychological, and social development. Functional imaging with PET and SPECT has been useful in a variety of seizure types and is typically more sensitive compared to anatomic imaging methods such as magnetic resonance imaging for localizing non-lesional seizure foci. SPECT and PET may be useful in guiding the strategy of implantation in patients submitted to undergo invasive recordings. However, the ability of PET and SPECT to localize a seizure focus may be crucial for tailoring the surgical resection area in patients with intractable seizures. Since most seizure cases begin in childhood, PET and SPECT imaging for seizure disorders is frequently used in this population. In this article, we review the literature on the current uses and indications of PET and SPECT in the study and management of epilepsy in children.
