Volumetric T1 and T2-weighted volumes were acquired on
38 MS patients with average disease duration of 2 years,
but grouped into two age brackets, and 52 age-group
matched controls. Manually delineated white matter (WM)
and grey matter (GM) lesions were lesion-filled in the
automated segmentation of GM and WM with Sienax and
FIRST. WM volumes were not significantly different
between early MS subjects and controls, however, GM and
especially non-peripheral GM volumes were, such as in
the thalamus and putamen (P<0.001 in each). The younger
MS group had significantly reduced volume in the caudate
and the hippocampus (P<0.001 for both), which was not
reflected in the older group.
