Table 1:

Structure volumes (in mm³) and tissue susceptibility values (in ppm) in the selected bilateral regions of interest obtained by manual delineation and the QSM/T1 multi-atlas approach in the leave-one-out test using the atlas set (subject n=10) and the corresponding correlations between these measures. Volume and susceptibility values are presented as mean ± standard deviation.
