Fornix (crus)/ Stria Terminalis – fxst

Protocol PDF Document (version 1.2): fxst  

Instructions:

1. Create two separate coronal seed regions (at approx. coronal slice 111), one for each side.

2. Create two separate coronal ROI regions (at approx. coronal slice 91), one for each side.

3. Create an ROA region and draw two sagittal ROA slice: medial to the left seed and medial to the right seed.

4. In the region list, check the left seed/ROI regions and ROA region, then run fiber tracking, based on this output, ROA placement will be clearer.

5. Using the same ROA file, draw two more ROA regions:
   1. on a coronal slice posterior to the seed regions
   2. on a coronal slice anterior to the seed regions

6. Check only the left seed/ROI region and ROA regions, then perform fiber tracking. Under the tract list, make sure only the desired left tract is checked and highlighted in purple. Save region, tract, and density files.

7. Uncheck the left seed/ROI region and check the right seed/ROI region and ROA region, then perform fiber tracking. Make sure only the desired right tract is checked and highlighted in purple. Save region, tract, and density files.
