There is preserved grey/white matter contrast with no significant binding of tracer to the cerebral grey matter on visual inspection or quantitative analysis. Tracer uptake conforms to the white matter distribution only, maintaining an arboreal pattern. Normal separation between the cerebral hemispheres has been preserved.
On quantitative analysis, the average SUVR is 0.96 (normal <1.26) and the centiloid value is 0.05 (normal <10).
