[Mristudio-users] effect of TE on FA

[Mark Wagshul]

Does anyone have data on this?  I have been able to find a limited number of papers.  There is a reference to a "dataset #4" of DTI data with varying TE's on the mBIRN site but I can't find the data on the site.  We have a pretty large dataset from over 60 relatively normal individuals (minimal to very mild TBI) with two DTI datasets at different TE's (65 vs. 84ms, same b-value) which seem to be showing the opposite effect from what we would expecting (FA is decreasing with TE, since the diffusion times are longer with the longer TE set, we would expect FA to increase).  I would appreciate comments, or like to know if anyone has any good data on these effects.  Thanks,

Mark
