Hi Chris,
they hypointense WM on the T1 (typically also hyperintense on a T2).
Unfortunately they are hard to distinguish from partial voluming on the
walls of the ventricle and from the more superior regions of the caudate,
unless you hae multispectral data (ideally a FLAIR).
cheers,
Bruce

What are white matter hypointensities supposed to represent? I'm seeing this
segmentation group a lot around the lateral ventricles, caudate, etc.
thanks,
Chris
