  1. The mean values of region-specific CV (i.e. inter-scanner variability in brain volumetry of GE vs. PHILPS, GE vs. SIEMENS and PHILIPS vs. SIEMENS) of the examined 15 subjects are displayed for each ABS tool
  2. GM gray matter, N.A: not available, WM white matter, VentralDC ventral diencephalon, L Left, R Right
  3. The average CV of FSL-FIRST for different brain substructures is the mean over the structures available for quantification in FSL-FIRST (i.e. hippocampus, amygdala, thalamus, caudate, putamen, pallidum and accumbens)
