MR Pediatric Total Spine WO, W, or W/WO – SINGLE or DOUBLE JUMP Protocol
Exam Notes
Last updated: 3/19/2021
Charge as: Total Spine W, WO or W/WO
Scanner preference: DCH7
Coil: NV and Anterior Torso Coil
Important Tech Notes
- Do not change parameters including sense factors to reduce scan time
- Do not increase FOV on any stations
- FOV should not exceed 450mm for any stations on any exam
- OK to decrease FOV
- Approximate scan times for Total Spine WO:
- Single Jump: 25 min
- Double Jump: 40 min
Single Jump Notes
- Neonates: the NV Array coil will accomplish the anterior portion if you get the child high enough in the coil.
- OK to reduce FOV to less than 450mm for small patients (Infants, etc)
- If you CANNOT get the entire spine in the 450mm FOV, you have to move to the double jump protocol.
Double Jump Notes
Do not use ScanAlign/MobiView.
| PLANE | WEIGHTING | MODE | SLICE/GAP | FOV | COVERAGE | NOTES |
|---|---|---|---|---|---|---|
| If <450mm | Scan as Single Jump | |||||
| If >450mm | Scan as Two Jumps, dividing into equal heights | |||||
| SAG | T2 3D | 3D | 1.2mm/-0.6 mm | 450mm max | Mid-clivus to the S4-5 “disc” level. No need to include coccyx unless there is an obvious mass in inferior sacrum. | Generate AX MPR at 1 mm/0 mm gap |
| SAG | T1 | TSE | 3mm/0mm | 450mm max | Same as Sag T2 3D | |
| SAG | T2 | mDIXON | 3mm/0mm | 450mm max | Same as Sag T2 3D | |
| If ordered with contrast, hand inject | ||||||
| +SAG | T1 | mDIXON | 3mm/0mm | 450mm max | Same as Sag T2 3D | |
| +AX | T1 FS | THRIVE/VIBE | 3mm/0mm | Manually plan 1-4 separate stations. Mid-clivus to the S4-5 “disc” level. No need to include coccyx unless there is an obvious mass in inferior sacrum. | Plan each station to be <4 minutes acquisition time |
