What defines a positive Florbetaben PET scan?
Two or more brain areas (each larger than a single cortical gyrus) in which there is reduced or absent gray-white contrast.
Area(s) of tracer uptake equal to or higher than that present in white matter extending beyond the white matter rim to the outer cortical margin involving the majority of the slices within at least one of the four brain regions.
One or more cortical gyri as bright or brighter than the middle cerebellar peduncle.
Three or more brain areas (each larger than a single cortical gyrus) in which there is reduced or absent gray-white contrast.
The criteria for determining amyloid PET scan positivity are identical across all radiotracers.
