Functional MRI applications in epilepsy surgery.

Area of Science:

• Neuroimaging
• Clinical Neuroscience
• Epileptology

Background:

• Functional magnetic resonance imaging (fMRI) is a rapidly advancing non-invasive neuroimaging technique.
• fMRI is widely used in psychology, cognitive neuroscience, and increasingly in clinical epilepsy management.
• Its application in pre-surgical assessment is crucial for patient care.

Purpose of the Study:

• To review current clinical applications of fMRI in pre-surgical epilepsy assessment.
• To examine emerging fMRI techniques with potential future clinical relevance.
• To highlight fMRI's role in guiding surgical interventions and preserving brain function.

Main Methods:

• Review of current literature on fMRI applications in epilepsy.
• Discussion of established fMRI paradigms for language and motor mapping.
• Exploration of advanced techniques like simultaneous EEG-fMRI.

Main Results:

• fMRI effectively determines language localization and laterality, reducing the need for invasive testing.
• Pre-surgical fMRI guides resection margins to preserve eloquent cortex.
• Simultaneous EEG-fMRI provides insights into seizure networks, with growing clinical use.

Conclusions:

• fMRI is an invaluable tool for pre-surgical epilepsy evaluation.
• Emerging fMRI techniques show significant promise for future clinical applications.
• fMRI enhances surgical planning and patient outcomes in epilepsy management.
