Standardization of amyloid quantitation with florbetapir standardized uptake value ratios to the Centiloid scale.

•Results permit conversion of florbetapir standardized uptake value ratio to the Centiloid scale.•Within-subject correlations with Pittsburgh compound B were high.•24.1 Centiloids equates to a standardized uptake value ratio of 1.10 that separates subjects with none to sparse plaques from those with moderate to frequent plaques in an autopsy-confirmed sample.
