Established methods of brain volume normalization on
T1-weighted images typically require affine registration
to a standard template, which can introduce a
significant amount of measurement noise. We have
developed a fully-automated method to compute a
normalized brain volume from T1w images by directly
estimating intradural volume. This method correlated
highly (r = 0.845) with an established method on T2w/PDw
images, when applied to a completed multiple sclerosis
clinical trial dataset of 131 patients, which included
both T1w and T2w/PDw sequences of each patient.
