FIGURE 1. Hypometabolic regions in patients with FTD compared with healthy controls. These regions are displayed on surface-rendered (top) and transaxial (bottom) images. Hypometabolic regions were displayed according to 2 different thresholds in green (P < 0.01; corrected, T = 5.18) and red (P < 0.0005; corrected, T = 6.29). Number in each transaxial brain image indicates distance (mm) from anterior commisureposterior commisure plane.

FIGURE 3. Scatter plots showing distribution of AIROI and AISPM values in patients with FTD. Positive AIROI and AISPM values indicate that right hemisphere was more hypometabolic than left hemisphere; negative values indicate the opposite. Closed circles denote significant hemispheric metabolic asymmetry.
