Summary Objective In 2014 the European Union–funded E‐ PILEPSY project was launched to improve awareness of, and accessibility to, epilepsy surgery across Europe. We aimed investigate current use of neuroimaging, electromagnetic source localization, imaging postprocessing procedures in participating centers. Methods A survey on clinical imaging, methods candidates distributed among 25 centers consortium. descriptive analysis performed, results were compared existing guidelines recommendations. Results Response rate 96%. Standard magnetic resonance ( MRI ) protocols are acquired at 3 Tesla by 15 1.5 9 Three perform 3T only if indicated. Twenty‐six different sequences reported. Six follow all guideline‐recommended with proposed slice orientation thickness or voxel size. Additional used 22 16 Interictal positron emission tomography PET is available centers; using 18F‐fluorodeoxyglucose FDG ). Seventeen postprocessing. Single‐photon computed SPECT 19 centers, which Four neither nor children. Seven apply magnetoencephalography MEG nine electroencephalography EEG localization. Fourteen combinations inverse volume conduction models used. Significance report a large variation presurgical diagnostic workup This diversity underscores need for high‐quality systematic reviews, evidence‐based recommendations, harmonization methods.
