anisotropic voxel resolution?
I was wondering if it had to do with the increased SNR being more
beneficial for accurate segmentation than the gain in resolution from a 1mm
isotropic voxel... or
Hi Antonio
yes, that should be fine. It probably reduces sensitivity in some regions,
but given the complexity of the folds I would expect it to average out.
That said, no one has ever done such a study so we really don't know.

Dear group,
I am new to FS and the ADNI protocol, thus my question: is it ok to have a
slice thickness of 1.2 mm and in-plane resolution of 1.05 mm for cortical
segmentation and brain volume analyses? This seems to be a sequence
suggested on the FreeSurferWiki (I am using a GE750 3T).
Doesn't the
