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

·         Do usual sagittal and coronal non-fat-sat PD




Place marker at the point of max tenderness or above and below region of interest.
