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.
