This study focuses on the application value of 18F-FDG, SV2A, and TSPO PET imaging in the preoperative localization of epileptogenic foci in epilepsy. 18F-FDG PET detects glucose metabolism in brain tissue and is characterized by reduced metabolism during the interictal period. It is currently the most commonly used localization method in clinical practice, especially suitable for temporal lobe epilepsy, but has limited sensitivity to foci with insignificant metabolic changes. SV2A PET targets synaptic vesicle proteins and reflects synaptic density, showing reduced uptake in epileptogenic foci areas. It has high localization accuracy, can effectively supplement the diagnosis of 18F-FDG PET-negative cases, and also has good application prospects in non-temporal lobe epilepsy. TSPO PET monitors microglial activation to reflect neuroinflammation, with increased uptake in epileptogenic foci areas, and has unique auxiliary diagnostic value in refractory epilepsy and cases with concurrent brain injury. The combined application of the three can provide a more comprehensive imaging basis for preoperative localization of epilepsy, helping to optimize surgical plans.
