Objectiveand Methods: In this study, atlantoaxial subluxations and their relationship with laboratory and clinical signs of rheumatoid arthritis were investigated by plain radiography, computed tomography, and magnetic resonance imaging. Results: We found that neither immulogical data nor clinical findings were predictive factors in the assessment of atlantoaxial subluxations. Conclusions: Magnetic resonance imaging including coronal plane sections appears to be the modality of choice for the diagnosis of atlantoaxial subluxations because of its ability to acquire direct multiplanar images.
