| Localizer (REF scan) |
Mode | Slice | Gap | FAT SAT | FOV | Scan Range | |
|---|---|---|---|---|---|---|---|
| AXIAL | 3D T1 | FFE | None | 26cm | DO NOT ANGLE. Cover above the vertex of the brain at least 1 cm. Cover the nose. | ||
| AXIAL | (GPI) MPRAGE | 3D | ISO | ISO | None | DO NOT CHANGE | DO NOT ANGLE. There should be plenty of slices for coverage built in. No need for extra coverage like for stereotactic sequences. If the slices don't cover the entire brain, position slice stack to cover from vertex down. Do not add slices. |
| AXIAL | DTI | 2 | 0 | None | 26cm | DO NOT ANGLE. Cover the Entire Brain. No need for extra coverage like for stereotactic sequences. |
A 3D t1 axial acquisition must be performed in conjunction with the DTI
