Between-tracer comparison of the SPITFIRE™ estimator in the ADNI cohort

Between-tracer comparison of the SPITFIRE™ estimator in the ADNI cohort. The spatial resolution estimation is consistent across the three different PET tracers.

--:--

To assess the consistency of the SPITFIRE™ estimator across tracers, we selected subjects with pairs of PET images with different tracers, but scanned no more than 3 months apart.

The figure shows scatter plots of the resolution estimation for each pair of tracers. Notice that, in each case, the correlation between tracers is slightly greater for the in-plane resolution as compared to the axial resolution, perhaps driven by the typically greater voxel size in the axial direction.
