Uncinate Fasciculus on DTI
Hi there,

Does anyone have a suggestion on how to map the uncinate fasciculus on DTI (single subject). I preprocessed our DTI images on FSL and am trying to use TrackVis to see the tracks. Although I can see the corpus callosum and corticospinal tracts nicely, I cannot seems to see the uncinate fasciculus despite using variously sized and positioned ROIs.
Any help would be greatly appreciated!
Thanks!

If you look at the anatomy of this tract, you can see a strong bend of the tract and a high probability of crossing. To visualize this path, it is preferable to use probabilistic tractography algorithms such as HARDI-CSD.

Hi,

Have you tried looking at Catani and Thiebaut de Schotten's protocol that they used for their white matter atlas (including uncinate): https://linkinghub.elsevier.com/retrieve/pii/S0010-9452(08)00123-8

At the end of the article they show the masks that they used (on FA images) to run the tractography. 

best,
Katherine

Hi if you have a large dataset and prefer to extract the uncinate from the tractography automatically, you can extract the uncinate using our atlas and accompanying whitematteranalysis software:
http://dmri.slicer.org/atlases/

If you are using Slicer (it seems this is one tool you are using based on another post) there is a tutorial about using regions of interest to extract tracts here: http://dmri.slicer.org/docs/

And the Slicer community answers questions here: https://discourse.slicer.org/

Hope this helps!
