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 axial non-fat-sat mid-TE instead of fat-sat

  •  Keep sagittal STIR               

     

  • Do coronal STIR instead of fat-sat mid-TE
  • If with Contrast, do non-fat-sat T1 post-contrast 
  •
