Voxel wise paired t-test analysis of visual negative subjects. Figure shows the paired t-tests results obtained from the voxelwise permutation analysis of participants not showing any elevated tracer uptake in regions typical of tau pathology (N = 15). Red represents areas where [18F]PI-2620 had significantly higher SUVR values, while blue represents areas where [18F]RO948 had significantly higher SUVR values. Significance level was set at 0.05 after false discovery rate correction
