Dear FSL users,
I am conducting FA value comparison between skeletonised FA and typical FA values.
Typical FA values acquired from non-skeletonised FA map using ROI drawing on Corpus Callosum in the midsagittal plane of the mean FA skeleton map.
I expected values between typical FA map and skeletonised FA map are not different drastically.
Interestingly, FA values from skeletonised FA map is approximately 50 % lower than that from typical FA map.
Is there any explanation on this difference?
Sincerely,
SC
