Rheumatoid arthritis of the craniocervical region by MR imaging: detection and characterization.

Abstract

Contrast-enhanced T1-weighted spin-echo MR imaging can discriminate between joint effusion and various forms of pannus in patients with rheumatoid arthritis of the craniocervical region. MR imaging also can detect joint effusion and pannus tissue in patients with negative radiographic findings. No relationship between MR imaging findings and clinical symptoms were found. Tissue enhancement and histopathologic findings correlated in a limited number of autopsies.
