Evaluation of [123I] MNI-308 and SPECT as a Marker of Beta-amyloid Protein Deposition in AD Subjects Compared to HC

Summary

The main objectives of this proposal are as follows: To assess the dynamic uptake and washout of 123-I MNI-308, a potential imaging biomarker for β-amyloid burden in brain, using single photon emission computed tomography (SPECT) in similarly aged Alzheimer's (AD) subjects and healthy controls To perform blood metabolite characterization of 123-I MNI-308 in healthy and AD subjects to determine the metabolic fate and nature of metabolites in assessment of 123-I MNI-308 as a single photon computed tomography (SPECT) brain imaging agent Evaluate the test/retest reproducibility of 123-I MNI-308 and SPECT in AD subjects and healthy control
