Notes: Use rest medial slabs to reduce respiratory motion- increase FOV to cover area of concern.

If hardware is present: Arthroplasty Do STIR instead of fat-sat mid-TE

·         Do post-contrast non-fat-sat T1 instead of fat-sat

Other Hardware: (If necessary)Do STIR instead of fat-sat mid-TE

·         Do post-contrast non-fat-sat T1 instead of fat-sat

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