Outcome Measures

Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Test-Retest Reproducibility [ Time Frame: 80-100 minutes postdose ]
    Evaluate test-retest reproducibility of flortaucipir for brain imaging of tau in healthy volunteers and subjects with cognitive impairment. Standard uptake value ratios (SUVRs) for each scan, normalized to the cerebellar crus. A combination volume of interest (VOI) = weighted average of parietal, temporal, and occipital regions was used. The protocol pre-specified that test-retest endpoint was to be calculated for the combined group of healthy volunteers and cognitively impaired subjects

  2. Test-Retest Reproducibility [ Time Frame: 110-130 minutes postdose ]
    Evaluate test-retest reproducibility of 18F-AV-1451 for brain imaging of tau in healthy volunteers and subjects with cognitive impairment. Standard uptake value ratios (SUVRs) for each scan, normalized to the cerebellar crus. A combination volume of interest (VOI) = weighted average of parietal, temporal, and occipital regions was used. The protocol pre-specified that test-retest endpoint was to be calculated for the combined group of healthy volunteers and cognitively impaired subjects
