FIGURE 3. Sagittal images (from left to right, MRI, composite SISCOM, and composite subtraction SPECT) and rainbow color scale for left MTLE group. At far right is composite subtraction SPECT image of MTS subgroup, matched to same MRI plane as left MTLE group. Sagittal view serves to highlight predominance of anterior temporal hyperperfusion, as well as extension of hyperperfusion into insula. This view shows sharp demarcation between regions of hyperperfusion in insula and adjacent frontal lobe.
