(b) Scatter plot showing the correlation between the DAT-SPECT measured in the putamen and the mean MD values computed within the region highlighted in red on panel (a), for HC (yellow triangles) and PD (red circles). (d) Scatter plot showing the correlation between the DAT-SPECT measured in the putamen and the mean GM volume estimated within the region highlighted in red on panel (c), for HC (yellow triangles) and PD (red circles). Plot legend reports Spearman’s correlation coefficients.
