sagittal

Sagittal planning

  • Cover the entire knee from above the patella to the tibial tubercle.
  • Cover through the entire menisci.
  • Align perpendicular to the femoral condyles and the medial aspect of the medial condyle.

Coronal planning

  • Cover the entire knee from above the patella to the tibial tubercle.
  • Cover through the entire menisci.
  • Align parallel to the femoral condyles.
  • Cover from the anterior patella to past the femoral condyles.

Conditional workflowSpecial SituationsAdjustments for contrast, hardware, and protocol-specific conditions.

Contrast indicated

  • Add axial T1 FS precontrast sequence.
  • Perform injection step.
  • Add axial T1 FS postcontrast sequence.
  • Add coronal or sagittal T1 FS postcontrast sequence.

Surgical hardware present

  • Document hardware-specific requirements if needed.
