Correlation maps between QTM velocity (mm/sec) and CBF (ml/100 g/min) in multiple regions, including GM, WM, FL, TL, OL, PL, Hippo, and DeepGM. The numbers shown in the maps are the correlation coefficients. The correlation is lower in the MCI and AD groups compared to NC group. (A) correlation in NC group; (B) MCI group; (C) AD group. Note that the same ROI correlations between QTM velocity and CBF are highlighted by black boxes, and insignificant correlations are blanked
