MR Hardware Total Spine WO or WWO
When to use OMAR/MARS:
Only use OMAR/MARS on the parts of the spine that contain hardware. If no hardware is present in a level of the spine, then use routine 2D TSE sequences instead.
When to use fat suppression on post-gad sagittal T1:
- Use SPIR fat suppression on post-gad sagittal T1 only if no hardware is present in that level of the spine.
- Do not use fat suppression on post-gad sagittal T1 if hardware is present in the level of the spine you are imaging.
Other notes:
Charge as: Total Spine WO or WWO
Scanner preference: 1.5T only.
Coil: On all of our systems except MR1: Add the torso coil anteriorly in combination with the table top and/or NV array coils.
