MR imaging of hip disorders.
Magnetic resonance (MR) imaging has been applied to the study of a variety of hip disorders, principally the evaluation of avascular necrosis. The authors reviewed their experience with MR imaging of a variety of pediatric and adult hip diseases. Attention to the details of the imaging technique is essential for maximizing the diagnostic potential of MR imaging in the work-up of hip disease. Specific protocols that incorporate surface coil imaging, oblique imaging planes, and alternative pulse sequences are the foundation of successful hip studies. Gradient-echo imaging is essential for evaluating cartilaginous disorders, particularly in pediatric patients. For patients to benefit from the diagnostic capabilities of MR imaging, an appreciation of the unique information it provides must be communicated to referring physicians. In addition, an awareness of the atypical and unique MR appearances of certain hip disorders is necessary for accurate interpretation.
