MAPT and supranuclear palsy, progressive, 1: Our previous studies, including correlations in 3 non-AD tauopathy cases who underwent imaging prior to death (two PSP and a MAPT P301L mutation carrier), showed elevated in vivo retention and tau pathology in basal ganglia, but no tracer binding in this region at postmortem by autoradiography, and no significant correlation between in vivo signal and tau burden in multiple ROIs [32].
