DTI-ALPS, VSRAD Z-score and MMSE score were compared with PiB centiloid after normalization. nDTI-ALPS (○) had a speeper slope and a better correlation coefficient (0.31, r = 0.65) compared to nVSRAD (▲, 0.16, r = 0.43) and nMMSE (■, 0.18, r = 0.61). Lines are linear regression lines for each pair of correlation.
