PET imaging results of three cases with favorable outcome but were discordant between SPM and 3D-SSP. In each panel, the upper part is the SPM-PET result (P < 0.001, voxel size 50 corrected), and the lower part is the SD-SSP-PET result with Z-score. (A) Case 5, the PEZ was localized at the right temporal lobe and underwent right anterior temporal lobe lesion resection. 3D-SSP showed a CS result with the PEZ of the right temporal lobe hypometabolism; however, SPM results were focused on the right occipital lobe hypometabolism. Considering the postsurgical pathology, the SPM result seemed untrustworthy. (B) Case 13, the right temporal and frontal lobes were considered to be PEZ. Overlapping hypometabolism regions were detected by SPM. In contrast, 3D-SSP only detected the epileptic focus in the right temporal lobe. Even though a very small metabolism was also found in the right frontal lobe by 3D-SSP, it is too small to account it as an epileptic focus, given the similar metabolism in the same position of the contralateral hemisphere. (C) Case 7, the PEZ was situated at the left temporal lobe and was confirmed by the postsurgical pathology. However, both 3D-SSP and SPM detected the hypometabolism of the left prefrontal lobe, not the temporal lobe.
