title: Magnetic resonance imaging in osteonecrosis of the femoral head.
abstract: Magnetic resonance imaging (MRI) has been used in the assessment of patients with osteonecrosis of the femoral head. Preliminary results indicate that the technique is sensitive to early changes that occur within marrow elements as well as to later changes that involve trabecular bone. Advantages of MRI include its noninvasiveness, the lack of ionizing radiation, a high sensitivity to pathologic changes in bone, and the capability of producing images of equal resolution in all planes.
