Patient preparation

If you use this ExamCard with the dS Knee 16ch the patient must be positioned supine and feet first.
Tips and hints to reduce metal artifacts in sequences:
  • Use TSE instead of FFE (also for the survey)
  • Use Uniformity Classic
  • Use short echo spacing and high TSE factor
  • Use a small WFS of 0.5 to 0.7
  • Use thin slices
  • Maintain good SNR (give up some in-plane resolution)
  • Use STIR, no spectral fat saturation

 

If you have to use a gradient echo the principles as outlined in the previous tips still apply.
