MR Lumbosacral Plexus WO or WWO MSK Protocol

Scan Notes:

MSK to read unless: 

  • It was previously read by Neuro (send to Neuro to read/protocol)
  • The order includes a Lumbar Spine, and/or is "lumbar to include sacrum” (send to Neuro to read/protocol)

FOV/Angulation:

  • Angle OBLIQUE to sacrum
  • Craniocaudad = L5 thru lesser trochanters
  • 
AP = sacrum thru pubic symphysis
  • 
Transverse = greater trochanter to greater trochanter

If hardware is present:

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