Presurgical Focus Localization in Epilepsy: PET and SPECT

Area of Science:

• Neuroimaging
• Epileptology
• Nuclear Medicine

Background:

• Drug-resistant epilepsy poses significant management challenges.
• Accurate localization of seizure foci is crucial for treatment planning.
• Advanced neuroimaging modalities offer potential for improved localization.

Purpose of the Study:

• To evaluate the role of PET and SPECT in localizing seizure foci.
• To highlight the importance of integrating imaging findings with comprehensive clinical data.
• To discuss the broader research applications of PET in epilepsy.

Main Methods:

• Review of Positron Emission Tomography (PET) and Single Photon Emission Computed Tomography (SPECT) applications in epilepsy.
• Emphasis on multimodal data integration: clinical, electrographic, and MRI.
• Discussion of PET ligand utility for neurotransmitter and inflammatory processes.

Main Results:

• PET and SPECT are valuable tools for seizure focus localization in refractory epilepsy.
• Interpretation requires contextualization with electroencephalography (EEG) and magnetic resonance imaging (MRI).
• PET offers expanded research capabilities, especially with specific receptor or inflammation ligands.

Conclusions:

• PET and SPECT aid in localizing seizure foci for drug-resistant epilepsy.
• Multimodal data integration is essential for accurate interpretation of imaging results.
• PET's research applications extend to neurotransmitter and inflammatory pathways in epilepsy.
