Magnetic Source Imaging / MEG
The Magnetic Source Imaging Lab at the University of Utah Clinical Neurosciences Center is a state-of-the-art diagnostic center for the evaluation of brain diseases, particularly epilepsy and tumors. The MSI Lab combines the power of the Unviersity of Utah’s 3Tesla MRI and our 306-channel MEG to provide the clearest view of brain function that can be obtained non-invasively. Fewer than 10 centers in the country can provide the service available at the University of Utah.Magnetoecephalography (MEG) involves the recording and analysis of minute magnetic fields produced by brain activity. In patients with seizures, MEG can document the presence of an epileptic focus, determine its location, and provide necessary information concerning options for surgical therapy. This is particularly helpful in determining treatment options for patients with inadequate localizing information or conflicting localization information.
MEG is a useful guide for the optimal placement of subdural EEG electrodes to help delineate seizure focus and minimize the volume of brain tissue resections required to achieve the treatment goal. The role of MEG is well-defined for pre- and post-operative epilepsy surgery evaluations.
