Hi All
I was wondering whether it's possible to compare FA/MD for DTI acquired with different TEs (80.4 vs. 86.4) and TRs (13200 vs 15100); all other acquisition parameters are the same. We have a group of patients acquired with the latter and a convenient set of control data acquired with the former, but higher TE/TRs seem to also produce higher FA. Is there any way to appropriately normalize the datasets or would multivariate statistics avoid this issue?
Thanks!
David
