Notes:
All scans include entire tarsals in FOV
If sag 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
