[Mristudio-users] temporal lobe tracts

[Siewmin Gan]

Dear all,            I am trying to reproduce some tracts associated with
the temporal lobe using the ROI drawing protocols from the paper
"Reproducibility of Quantitative Tractography Methods Applied to Cerebral
White Matter". The acquisitions of the DTI are similiar to the paper. I had
good results with the ILF, but couldn't get the uncinate fasciculus and
cingulum in controls and patients data. For these tracts, after I draw the
1st ROI with the "Or" function, I couldn't see tracts in the specified
area/slice mentioned in the protocol to place the 2nd ROI.

 I wonder if I have misinterpreted the protocols. Secondly, the dti slices
were acquired parallel to the AC-PC line in the paper and the protocols are
based on anatomical landmarks. If the dti data I tried on are not acquired
exactly parallel to the AC-PC line, would it make a difference in the
reproducibility using the protocol? Much appreciated if any of you have
tried and could derive these two tracts.

Many Thanks

Siewmin
