We examined 6 cases of rheumatoid arthritis in the upper or lower cervical spine by plain radiography, myelogram, X-ray CT and magnetic resonance imaging (MRI) . Among these, MRI provided the best resolution of tissuse surrounded by bones, as well as of minute differences among various tissues. Enhancement of the differences between normal and diseased parts within tissues was also made possible with MRI by altering the imaging parameter. MRI was useful not only for depicting boney abnormalities in the cervical spine that are associated with rheumatoid arthritis, but also for directly observing the effects of the disease process on the spinal cord.
