Fig. 4From: FDG-PET hypermetabolism is associated with higher tau-PET in mild cognitive impairment at low amyloid-PET levelsFDG-PET levels in MCI subgroups compared to CN and AD control groups. Mean FDG-PET levels for each cluster (arranged by anatomical adjacency) compared to CN and AD dementia subjects. MCI subjects were stratified by high and low tau PET (median split) and amyloid PET (global amyloid-PET SUVR ≥ 1.11). Significant differences between groups are indicated by *p < 0.05, **p < 0.01, and ***p < 0.001; one-way ANCOVA with post hoc t test between each pairBack to article page
