What is the proper MRI technique used for the evaluation of hip pain?
The exact MR imaging sequence combination depends on the scanner, clinical indication, patient factors, and radiologists’ preferences. In the setting of trauma, the entire pelvis and both hips should be included in at least one (coronal and/or axial) plane. For evaluating joint pathology, such as labral tears or cartilage abnormalities, a smaller field of view with a lower slice thickness producing higher spatial resolution images should be used. Both T1-weighted (for anatomic detail) and fluid-sensitive sequences such as fat-suppressed T2-weighted, fat-suppressed proton density (PD)-weighted, or short tau inversion recovery (STIR) images (for detection of bone marrow edema) are necessary.
