Baseline results. (A) A scatter plot of PiB retention values at baseline. The y-axis contains the neocortical PiB retention values, normalized by a DVR. The black line indicates the 1.20 cut-off used to classify Aβ+ and Aβ− MCIs. (B) Baseline functional MRI (fMRI) activity. The y-axis contains the average beta-estimate from both left and right hippocampus. (C) Average baseline hippocampal volume (HV). The y-axis contains the total hippocampal volume in mm3 of both left and right hippocampus. (D) Baseline Mini-Mental State Examination scores (MMSE). (E) Baseline Clinical Dementia Rating Sum of Boxes scores (CDRSB). The Aβ− MCI group is shown in blue and Aβ+ MCI in red. Error bars denote the standard error of the mean.
