Fig. (3) Regional [¹¹C]PBB3 SUVR values in ANDE and HC. Significantly high accumulation was found in the parietal cortex, precuneus and the lateral temporal cortex of NFTPD (p<0.05). To evaluate effect of atrophy on apparent [¹¹C]PBB3 accumulation, each side was separately analyzed in cases with AGD. Less/ More indicate side of less or more atrophy on MRI. No correlation was found. Open square indicates significantly high accumulation compared to NC.
