FIGURE 1.
Effect of PVC for the MTL and cortex, across diagnostic groups at baseline. Partial volume correction increased uptake for all regions and across all diagnostic groups (P <0.001). The effect of PVC on the MTL was greater in the DAT group compared with the MCI group, which was greater than the control group (P < 0.001). The linear trend was not significant for the cortex (P = 0.37). This analysis was conducted on the HC (n = 55), MCI (n = 53), and DAT (n = 7) groups.
