Neuroimaging of Epilepsy

Area of Science:

• Neurology
• Radiology
• Medical Imaging

Background:

• Brain imaging is essential for epilepsy diagnosis and evaluation.
• Structural imaging (MRI, CT) identifies epileptogenic lesions.
• Functional neuroimaging aids focus identification and surgical planning for drug-resistant epilepsy.

Purpose of the Study:

• Provide an overview of imaging modalities for epilepsy.
• Discuss important imaging pathologies in epilepsy.
• Outline the role of imaging in epilepsy diagnosis, evaluation, and treatment, including surgery.

Main Methods:

• Review of structural imaging modalities (MRI, CT).
• Exploration of advanced MRI techniques (e.g., 7-Tesla MRI, HARNESS-MRI protocol).
• Discussion of functional imaging techniques (EEG-fMRI, magnetic source imaging).

Main Results:

• Standardized MRI protocols (HARNESS-MRI) improve imaging consistency.
• Advanced MRI and postprocessing techniques enhance sensitivity for detecting lesions.
• Functional imaging offers complementary methods for seizure focus localization.
• New pathologies (MVNT) and appreciated pathologies (encephaloceles) are identified.

Conclusions:

• Neuroimaging is critical for comprehensive epilepsy care.
• Advanced and functional imaging techniques improve the detection and localization of epileptogenic zones.
• Tailored imaging strategies are vital for surgical planning in drug-resistant epilepsy.
