Measure
AD Subjects
Male or female subjects \> 50 years old; probable AD according to NINCDS-ADRDA criteria; MMSE 10-24
AD Subjects: Slow vs. Fast Bolus Group
Same inclusion criteria as AD subjects. The first injection given as a rapid bolus (\< 5 second injection, with immediate flush). The second injection given as a slow bolus (approximately 20 to 30 second injection with a flush delayed by 10 seconds after dose administration).
Control Subjects
Healthy male or female subjects; 35-55 years old; no evidence of cognitive impairment; MMSE 29 or higher

PRIMARY outcome

Timeframe: 50-70 min after injection

Population: Due to poor subject positioning that resulted in an incomplete brain image on the retest image day, accurate quantitative analysis for one healthy control was not possible, and the subject was excluded from the SUVR-based analyses.

Standardized Uptake Value ratio (SUVR) is the ratio of tracer uptake in predefined cortical regions, relative to uptake in the whole cerebellum.
