Comparison of inter-individual variability of measured amyloid burden (A, B), mean amyloid burden in people with minimal amyloid burden (C, D), and in people with substantial amyloid (E, F), for different quantification methods, i.e. with or without partial volume correction (A, C, E), and using different reference region (B, D, F). RSF: Regional spread function based partial volume correction; NonRSF: without partial volume correction; **significant difference (p < 0.0005) that survives Bonferroni correction for multiple comparisons. The analysis was based on the cross-sectional analysis of Knight ADRC data.
