MR Knee WO MSK Protocol

Scan notes:

ACL hardware: Usually does not obscure internal structures enough to warrant changing the protocol – stick to the usual protocol unless it obviously obscures too much.

Femoral / Tibial rods and plates: (If Necessary)

  • Do non-fat-sat mid-TE (axial, sagittal, coronal) instead of fat-sat
  • Add a coronal STIR
