Objectives: To evaluate a novel method for localization of subdural electrodes in presurgical assessment of patients with drug-resistant focal epilepsy. Methods: We studied forty consecutive patients with drug resistant epilepsy in whom subdural electrodes were implanted for presurgical evaluation. Electrodes were detected on post-implantation brain CT scans through a semiautomated procedure based on a MATLAB routine. Results: In each patient, all electrodes could be correctly localized and visualized in a stereotactic space, thus allowing optimal surgical planning. The mean mismatch between the 3D images and the photographs was 2.8 mm. Conclusions: This procedure allowed to localize subdural electrodes and to establish the spatial relationship of each electrode to the underlying brain structure, either normal or damaged, on brain convessity, basal and medial cortex.
