Clinical magnetoencephalography for neurosurgery.

Area of Science:

• Neuroimaging
• Neurosurgery
• Biophysics

Background:

• Noninvasive neuroimaging is crucial for surgical planning and patient risk assessment.
• Magnetoencephalography (MEG) is a key technique for neurosurgical planning.
• Common neurosurgical planning tasks include localizing epileptic discharges, determining verbal processing dominance, and mapping eloquent cortex.

Observation:

• MEG is most effective when integrated with structural imaging modalities.
• Structural magnetic resonance (MR) imaging and MR diffusion imaging are commonly combined with MEG.
• This article provides a historical overview of clinical MEG.

Findings:

• The article reviews the fundamental biophysics of MEG.
• It outlines essential neurosurgical applications of MEG.
• MEG aids in precise localization and functional mapping for surgical interventions.

Implications:

• Enhanced surgical planning through accurate noninvasive neuroimaging.
• Improved patient counseling regarding surgical risks.
• MEG, particularly when combined with MRI, offers significant advancements in neurosurgical procedures.
