MR Ankle WO MSK Protocol
Scan notes:
For Ligament Tear, Trauma, AVN, Stress F/x, Plantar Fasciitis:
If sag T2 Fat Sat has poor fat suppression, consider STIR (TE=40) instead.
If hardware is present:
- Do AX non-fat-sat mid-TE instead of fat-sat
- Keep SAG STIR
- Do COR STIR instead of fat-sat mid-TE
- If ordered with Contrast, do non-fat-sat T1 post-contrast
