MR Pediatric Total Spine WITH only - Double jump
Protocol Definition
- Version (Last Updated):
2025-04-29
- Scanner Preference:
DCH7
- Coil:
NV and Anterior Torso Coil
- Indications:
- Surveillance of contrast-enhancing tumors in the spinal canal.
- Drop-metastases.
- Field-of-View (FOV):
One jump or two jumps?
Sagittal coverage should extend from mid-clivus to the S4-S5 "disc" level.
- If this distance < 450 mm, then use a single jump for the whole spine.
- If > 450 mm, then use two jumps, dividing into equal lengths.
- Technical Notes:
IMPORTANT — Zero gap for all sequences (contiguous with no gaps).
- Do not change parameters including sense factors to reduce scan time.
- FOV should not exceed 450mm for any stations on any exam.
- OK to decrease FOV.
- Do not use ScanAlign/MobiView.
