Resources for the Diagnosis of Epilepsy

Accurate diagnosis of epilepsy and related disorders is the key to effective treatment. The UF Comprehensive Epilepsy Program team is experienced in the most advanced diagnostics, and offers a full range of modalities. In striving to offer the most advanced diagnostic methods, we include EEG, outpatient daylab videoEEG, outpatient ambulatory EEG, inpatient video EEG, intraoperative and extraoperative brain mapping, polysomnography, and MSLT. In addition, imaging modalities including 3T MRI, functional MRI, positron emission tomography (PET), and Single Photon Emission Computed Tomography (SPECT) are available to help diagnose and classify seizure disorders and related conditions.

EEG (ElectroEncephaloGraphy)

  • Electroencephalography is a measurement of the electrical activity of the brain by recording from electrodes placed on the scalp. Includes video EEGs.

MRI (Magnetic Resonance Imaging)

  • A method of creating images of the structure and contents of the brain using a powerful, uniform magnetic field.

PET (Positron Emission Tomography)

  • An advanced imaging technique that involves the acquisition of images of the brain based on the detection of radiation from the emission of positrons. Positrons are tiny particles emitted from a radioactive substance administered to the patient.

Ictal SPECT (Single Photon Emission Computed Tomography)

  • SPECT scans show brain function (what the brain is doing). SPECT involves an intravenous injection of two substances that are given during or immediately following a seizure (Ictal SPECT).
