Recommended Musculoskeletal(MSK) Pelvis MRI Protocols and Planning

MSK Pelvis MRI Localiser

A three-plane T2 HASTE/T1 GRE localizer must be taken at the beginning to localize and plan the sequences. Typically, localizers take less than 25 seconds, and you have the option to use either T2 HASTE or T1 GRE low-resolution scans for this purpose.

T1 tse coronal 4mm

Plan the coronal slices on the axial plane; angle the positioning block parallel to the right and left femoral heads. Check the positioning block in the other two planes. An appropriate angle must be given in the sagittal plane (vertically across the pelvis or parallel to the femur in a straight leg position). The slices should sufficiently cover the entire pelvis, extending from the anterior abdominal wall to the buttock region. The field of view (FOV) should be large enough to accommodate the bony pelvis, spanning from 2 inches above the iliac crest to two inches below the pubic symphysis.

T1 tse axial 4mm

Plan the axial slices on the coronal plane and angle the positioning block parallel to both the right and left femoral heads. Check the positioning block in the other two planes to ensure an appropriate angle is maintained in the sagittal plane. This angle should be either horizontally across the pelvis or perpendicular to the femur in a straight leg position. The slices must be sufficient to cover the MSK pelvis from 1 inch above the iliac crest to 2 inches below the pubic symphysis. The FOV (field of view) must be large enough to accommodate the whole pelvis, usually ranging from 350 to 450mm.

T2 tse sagittal 5mm

Plan the sagittal slices on the coronal plane; angle the positioning block parallel to the lumbar spine and pubic symphysis. Check the positioning block in the other two planes. An appropriate angle must be given in the axial plane (parallel to the linea alba and median sacral crest). Slices must be sufficient to cover the entire pelvis from right to left. The FOV (field of view) must be large enough to accommodate the whole pelvis, usually ranging from 350 to 450mm.
