Example of ESI when the segmentation was inaccurate. The patient was operated in the right temporal lobe and was seizure-free after the resection. In panel A, the pre-resection MRI shows a large lesion in the left frontal region containing CSF. The segmentation algorithm marked this part as bone (outlined by yellow lines). Thus these voxels are labeled as skull tissue in the FEM and the resulting ESI (D) shows a maximum in the mesial frontal region. In contrast, LSMAC and BEM ESI (B and C) show accurate localization of the ESI-max in the right mesial temporal lobe.
