[Magnetic resonance tomography of the craniocervical junction in chronic polyarthritis].

Magnetic resonance imaging and conventional radiographs and tomograms were correlated in 61 patients with chronic polyarthritis. Radiographs of the occipito-cervical junction only demonstrated bone lesions, erosions were detected on conventional tomograms. MRI was adequate for demonstration of bone abnormalities and soft tissue lesion and was especially suitable for detection of complications at the cervical spinal cord.
