Fig. 1

Group averaged QTM velocity in MNI template. (A), (B), and (C) are QTM velocity in NC, MCI, and AD, respectively. QTM velocity shows decreased pattern across NC, MCI, and AD groups in axial and coronal views. Red arrows point to the hippocampus in coronal view to show the QTM velocity across groups. We see a drastic QTM velocity reduction in the hippocampus from NC to MCI and AD
