PRIMARY outcome

Timeframe: 50-60 min after injection

Population: 4 subjects in AD group and 1 subject in the healthy elderly group were excluded due to poor placement and/or excessive movement in the scanner during the 200-minute procedure.

Standardized Uptake Value ratio (SUVR) is the ratio of tracer uptake in predefined cortical regions, relative to uptake in the cerebellum gray matter. Total scan length was 200 min.
