Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
Change in Total Accuracy (MIMNeuro Software, Low Accuracy Readers)
Tidsramme: Scan acquired 50-60 min post-injection
|
Evaluate whether the addition of quantitation as an adjunct to qualitative interpretations (VisQ) significantly improved the total accuracy of Amyvid scan interpretation in lower accuracy readers.
Only the 46 scans with autopsy from A07/A16 are used for this outcome measure.

Change in Total Accuracy (MIMNeuro Software, All Readers)
Tidsramme: Scan acquired 50-60 min post-injection
|
Evaluate whether the total accuracy of Amyvid VisQ interpretation was non-inferior to the qualitative scan interpretation alone.
Only the 46 scans with autopsy from A07/A16 are used for this outcome measure.
|
Scan acquired 50-60 min post-injection

|
Change in Reliability (MIMNeuro Software)
Tidsramme: Scan acquired 50-60 min post-injection
|
Evaluate whether VisQ interpretation significantly improved the reliability of Amyvid scan interpretation compared with qualitative scan interpretation alone.
The scan interpretation reliability will be evaluated using Fleiss' Kappa statistics.
