Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The main objectives of this proposal are as follows: To assess the dynamic uptake and washout of 123-I AV51, a potential imaging biomarker for β-amyloid burden in brain, using single photon emission computed tomography (SPECT) in similarly aged healthy controls and Alzheimer's (AD) subjects To perform blood metabolite characterization of 123-I AV51 in healthy and AD subjects to determine the metabolic fate and nature of metabolites in assessment of 123-I AV51 as a single photon computed tomography (SPECT) brain imaging agent Evaluate the test/retest reproducibility of 123-I AV51 and SPECT in AD subjects and healthy controls
