Recommended Hip MRI Protocols, Parameters, and Planning

Hip MRI localiser

A three-plane localizer must be taken at the beginning to localize and plan the sequences. Localizers are normally less than 25 seconds, T1-weighted low-resolution scans.

T1 tse coronal 3mm SFOV unilateral

Plan the coronal slices on the axial plane. Angle the positioning block perpendicular to the acetabulum (i.e., parallel to the femoral head and neck). Check the positioning block in the other two planes. An appropriate angle must be given in the sagittal plane (perpendicular to the acetabulum). The slices should adequately encompass the hip joint, starting from the ischial tuberosities and extending up to the line of the pubic symphysis. To minimize ghosting artifacts resulting from peristalsis, vascular pulsation, and breathing, consider incorporating a saturation band at the top and bottom of the coronal block.

T1 tse axial 3mm SFOV unilateral

Plan the axial slices on the coronal plane and angle the positioning block horizontally across the femoral heads. Check the positioning block in the other two planes to ensure an appropriate angle is maintained in the sagittal plane, which should be perpendicular to the femur. The slices must be sufficient to cover the hip joints from 1 inch above the anterior inferior iliac spine to 1 inch below the lesser trochanter. To minimize ghosting artifacts resulting from peristalsis, vascular pulsation, and breathing, consider incorporating a saturation band at the top and bottom of the axial block.

T2 TSE sagittal 3mm SFOV unilateral

Plan the sagittal slices on the coronal plane; angle the position block parallel to the femur. Check the positioning block in the other two planes. An appropriate angle must be given in the axial plane (perpendicular to the femoral head). Slices must be sufficient to cover the hip joint from outer cortex of the greater trochanter up to the inner portion of the acetabulum. To minimize ghosting artifacts caused by peristalsis and breathing, consider using a saturation band over the axial block.

Optional Scans

PD fat sat axial oblique 3mm SFOV affected side

Plan the axial oblique slices on the coronal plane, angling the positioning block parallel to the femoral neck. Verify the positioning block alignment in the other two planes. Ensure an appropriate angle is established in the axial plane, perpendicular to the femoral head. The slices should adequately cover the hip joint, spanning one inch above the superior border of the acetabulum to one inch below the inferior border of the acetabulum. To minimize ghosting artifacts caused by peristalsis and breathing, consider using a saturation band over the axial oblique block.

Plan the sagittal oblique slices on the coronal plane; angle the positioning block perpendicular to the femoral neck. Check the positioning block in the other two planes. Ensure an appropriate angle is set in the axial plane (perpendicular to the femoral head). The slices should sufficiently cover the hip joint, extending one inch above the acetabulum to one inch below the greater trochanter. To minimize ghosting artifacts caused by peristalsis and breathing, consider using a saturation band over the sagittal oblique block.

Plan the axial 3D block on the coronal plane and angle the positioning block horizontally across the femoral heads. Check the positioning block in the other two planes to ensure an appropriate angle is maintained in the sagittal plane, which should be perpendicular to the femur. The slices must be sufficient to cover the hip joints from 1 inch above the anterior inferior iliac spine to 1 inch below the lesser trochanter.
