Fig. 3 — MRI and FDG-PET results for the comparison of three subgroups of MCI converters split by time to conversion compared to the same group of control subjects. a) MRI (blue: atrophy) and FDG-PET (red: hypometabolism) results plotted onto an averaged brain. Overlapping results are displayed in violet. Results for different subgroups are separated by columns. b) Number of significant voxels (p = 0.001 uncorrected at voxel level and p = 0.05 FWE corrected at cluster level) detected in each comparison in FDG-PET (red) and MRI (blue). AD Alzheimer's disease, FDG-PET [18F]fluorodeoxyglucose positron emission tomography, FWE family-wise error, MCI Mild Cognitive Impairment, MRI structural magnetic resonance imaging, * indicates a significant difference between modalities within the condition, ** indicates a significant difference to all other conditions within the modality.
