Spin Echo Sequences

  1. SPin echo sequences produce what kind of weighted images
    T1 t2 or proton density
  2. in a spin echo sequence tr controls what
    t1 weighting
  3. a short tr maximazes what in spin echo
    t1 weighting
  4. a long tr maximizes what
    proton density
  5. what does te control
    t2 weighting
  6. a short te _________ t2 weighting
    minimizes
  7. a long te _______ t2 weighting
    maximizes
  8. what are the typical values for a long and short tr
    • long 2000msĀ 
    • short 300-700 ms
  9. what are the typical values of long and short te
    • long te 60ms+
    • short te 10-25ms
