Outcome Measures

Primary Outcomes (2)

  • Inter Rater Reliability

    Measure of agreement among readers using a binary visual read method (amyloid positive/negative) calculated using Fleiss' kappa. All scans were read in a blinded fashion without access to clinical information.

    Scan acquired 50-60 minutes post injection

  • Percent Agreement with Expert Panel

    Individual reader scan results will be compared to the expert panel's consensus rating for each scan.

    Scan acquired 50-60 minutes post-injection

Secondary Outcomes (2)

  • Change in inter reader reliability after application of quantitation software

    Scan acquired 50-60 minutes post injection

  • Change in agreement with expert panel

    Scan acquired 50-60 minutes post-injection

Study Arms (1)

Drug: Florbetapir (18F)

Interventions

No Florbetapir (18F) will be administered in this study.
