Tract-of-interest (TOI) based fiber tracking (FT).
| Tract | Seed ROI | Target ROI | |
|---|---|---|---|
| Fasciculus uncinatus | bvFTD-stage 1 | ±39/-1/-23 | ±14/48/-5 |
| Corticostriatal path | bvFTD-stage 2 | ±23/22/12 | ±13/38/36 |
| Corticospinal tract | bvFTD-stage 3 | ±27/-18/18 | ±19/-40/58 |
| Optic radiation | bvFTD-stage 4 | ±45/-40/-3 | ±26/-82/2 |
| Superior cerebellar peduncle | reference | 0/-29/-25 | ±27/-67/-42 |
Montreal Neurological Institute (MNI) coordinates for seed and target ROIs for the respective FTs for the TOI approach. ROI sizes were 10 mm for all seed ROIs and 20 mm for all target ROIs.
