Simple group mean difference (A), pooled SD (B), and effective contrast (C) between AD patient (n = 11) and control (n = 16) groups are shown for SUVRs over 9 time windows (only 20-min windows labeled on abscissa) for representative group of ROI. (D) Averaged mean effective contrast and simple difference across all ROIs are shown. Difference data were scaled by arbitrary number (4.087) to show this curve on same scale as effect size curve. AVS = anterior ventral striatum; DFC = dorsal frontal cortex; MTC = mesial temporal cortex; OCC = occipital cortex; OCP = occipital pole; PAC = pregenual anterior cingulate; PAR = parietal cortex; SMC = sensory-motor cortex; THL = thalamus.
