MR Orbits WWO Neuro Protocol
Last updated: 3/18/22
Charge as: Orbits WWO
Scanner preference: Avoid MR1, if possible.
Coil: Head
Coronal orbits coverage: Anterior margin of globe to anterior surface of pons, perpendicular to axis of the orbital segment of the optic nerves.
Axial orbits coverage: Superior margin of orbital rim to inferior margin of orbital rim, angled to be in-plane with the orbital segments of the optic nerves.
| Plane | Weighting | Mode | Slice (mm) | Gap (mm) | FAT SAT | FOV (cm) | MPR | Notes |
|---|---|---|---|---|---|---|---|---|
| AXIAL | DWI | 2D TSE or RESOLVE | 2 | 0.2 | YES | 17 | no | Small FOV centered on orbits. TSE or RESOLVE to avoid warp (avoid conventional EPI). Send only B1000 & ADC. Axial coverage details above. |
| AXIAL | T2 | 2D TSE | 2 | 0.25 | Dixon: InPhase & Water only | 17 | no | Orbits only. Axial coverage details above. |
| COR | STIR | 2D STIR | 2 | 0.25 | STIR | 17 | no | Orbits only. Coronal coverage details above. |
| COR | T1 | 2D TSE | 2 | 0.25 | Dixon: InPhase & Water only | 17 | no | Orbits only. Coronal coverage details above. |
