MR Full Body WO (MSK) Protocol
Scan Notes
If MSK MD ordered the exam, run the MSK protocol. If body MD ordered the exam, run the body protocol.
- NV Coil, and both XL Torso Coils. Use the plastic coil holder for the lower station over the feet. Coils should cover entire body through the feet
- Bellows
- Cover from Apex of head through toes, bilateral. No need to include arms
- Keep patient as flat as possible, do not give them the large leg support pad (a pillow is ok)
- Run as planned in the scanner. Don’t change parameters
- Run sequences in order as they are planned in the scanner
- If you change the FOV, you must change the FOV for all linked sequences (according to the geo names)
- You can add slices on one station to increase coverage if needed, or add an entire additional station (but adding slices will be easier)
- Adding slices to the abdomen station will increase breath holds, and is not always recommended

| Plane | Weighting | Add Slices? | Angle? | Change FOV? | Reconstruct | Notes |
|---|---|---|---|---|---|---|
| SAG survey | - | - | - | - | - | Landmark on glabella. Generate Mobiview. |
| COR survey | - | - | - | - | - | Position coronal survey lower if the feet were cut off on the sag survey. Generate Mobiview. |
| Brain Survey | - | - | - | - | - | Position survey as you normally would for a brain |
| AX | T2 Flair | - | Ok to angle | - | n/a | Cover from apex through skull base. |
| AX | DWIBs | Add slices to cover from skull base through feet if needed | No angle | - | Create spins and MOBIVIEW. See notes for instructions. | Stations: top, upper, middle, lower, thigh, knee. Cover from slightly above skull base through toes. This will be multiple stations. Do not change geonames. |
| Cor | T1 TB | If need more coverage, increase the FOV for the chehead (the uppermost station). | No angle | If need more coverage, increase the FOV for the chehead (the uppermost station). | SELECT ONLY THE T1 SCANS, RIGHT CLICK AND MOBIVIEW. Make an MPR from the mobiview. | stations: feet, legs, abdpel, chehead. Cover from slightly above skull base through toes. This will be multiple stations. Do not change geonames. |
| Cor | STIR | If need more coverage, increase the FOV for the chehead (the uppermost station). | No angle | If need more coverage, increase the FOV for the chehead (the uppermost station). | Same mobiview/MPR instructions as COR T1 | stations: feet, legs, abdpel, chehead. Cover from slightly above skull base through toes. This will be multiple stations. Do not change geonames. |
| Sag | T1 | If need more coverage, increase the FOV for the chehead (the uppermost station). | OK to angle. | If need more coverage, increase the FOV for the chehead (the uppermost station). | MOBIVIEW, and create MPR | sag spine up, sag spine lo. Cover from skull base through feet. Do not change geonames. |
| Sag | SPIR | If need more coverage, increase the FOV for the chehead (the uppermost station). | OK to angle. | If need more coverage, increase the FOV for the chehead (the uppermost station). | MOBIVIEW, and create MPR | sag spine up, sag spine lo. Cover from skull base through feet. Do not change geonames. |
POST PROCESSING
- DWIBS: select all of the DWIBS sequences. Right click and choose VolumeView. Choose “star man”, “compose” and “dwibs spin”. Call the sequence “dwibs spin” and “generate”. Close the window. Then select all of those spins you just made, and create a mobiview.
- TI & STIR COR: SELECT ONLY THE T1 (or STIR) SCANS, RIGHT CLICK, and choose MOBIVIEW . Once that is complete, right-click on the Mobiview sequence you just made, and create an MPR.
- SAG SPINE: Mobiview and MPR with the same steps as the COR
