a

Presented as Mean ± Standard Deviation. Regional VT values were generated using metabolite-corrected arterial input function and 90 minute dynamic data.

b

Spearman’s rank correlation analysis was applied to each test of correlation between age and regional VT generated using Logan analysis. Cortex, CTX; Region of Interest, ROI.

*

P < 0.0056, which marks significance after applying Bonferroni correction for the nine regions tested.
