MR Pediatric Total Spine WO - Double Jump
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.
Should the coccyx be included in the FOV?
Include the coccyx only if the exam is for sacral dimple, tethered cord, syrinx or chiari. For other indications, the FOV can end at S4-S5.
Should an axial non-contrast T1 of the filum/lumbar spine be included?
For this Peds Total Spine WO protocol, a Lumbar axial T1 is required in all cases.
Other notes:
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.
- Approximate scan times for Total Spine WO:
- Single Jump: 25 min
