MSK protocol

Hip MRI

Hip MRI for arthritis, labrum tears, avascular necrosis, and traumatic or pathologic fracture. Begins with bilateral coronal sequences for side-to-side comparison, then proceeds to focused unilateral axial, sagittal, and coronal sequences on the affected side. Routinely performed without contrast.

For protocol planning and internal reference only. Follow institutional MRI safety screening, contrast, dosage, and GFR policies.

PositioningSlice PlanningPlane-specific planning instructions and guide images for technologists.

sagittal

Sagittal unilateral planning

  • Align parallel to the plane of the outer rims of the acetabulum, from the roof of the acetabulum through the greater trochanter.
  • FOV covers from superior to the acetabulum through the lesser trochanter.

axial

Axial unilateral planning

  • Sequences are acquired orthogonally — no angle applied.
  • FOV covers the entire soft tissues of the affected hip from superior to the acetabulum through the lesser trochanter.

coronal

Coronal planning

  • Bilateral: align parallel to the plane of both femoral heads. FOV covers from above the iliac crest to just below the lesser trochanter, soft tissues from left to right.
  • Unilateral: align parallel to the femoral neck, covering the immediate soft tissues of the hip joint from superior to the acetabulum through the lesser trochanter.
Anatomic extentCoverage RulesMinimum coverage expectations and alignment rules.

coronal

Coronal bilateral field of view

Above the iliac crest to just below the lesser trochanter, soft tissues left to right. Aligned parallel to both femoral heads.

General

Unilateral field of view (axial and sagittal)

Superior to the acetabulum through the lesser trochanter, focused on the affected hip.

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

Surgical hardware present

  • Add Axial STIR sequence.
  • Add Coronal STIR sequence.
  • Add Sagittal STIR sequence.

T2 FS inhomogeneity

  • Use STIR instead of T2 FS when fat suppression is inhomogeneous.
