MRI of atlanto-odontoid osteoarthritis.
We present the MRI appearances of advanced degenerative changes at the atlanto-odontoid (AO) joint. Changes including obliteration of the joint space, subchondral sclerosis and osteophytosis were clearly depicted on fast gradient-echo T1-weighted MRI images. Recognition of these changes may be helpful in the diagnosis in patients with suboccipital pain.
