Hi Rob,
Thank you for your response. It has been a long time since I asked this question; however, as I am revisiting it, I was wondering if it would be possible to further elaborate on your response.
In particular, I have single-shell DTI data with 30 directions and b-values of 0 and 1000 s/mm². I have performed tractography on this dataset, used the Dehollander algorithm, applied the msmt_csd technique to generate FODs, and utilized mtnormalize. Additionally, I have assigned the entire Edema, Contrast-Enhancing Tissue, and Necrosis regions as the pathology under the 5th volume in the ACT 5tt image.
Could you explain how MRTrix resolves fiber tracts within the Edema region in this scenario?
Additionally, how can tractography be performed specifically within the Edema region alone?
Thanks,
Parand
