Abstract:
This paper presents the metacarpophalangeal (MCP) joint magnetic resonance images of the EULAR-OMERACT rheumatoid arthritis MRI reference image atlas. The illustrations include synovitis in the MCP joints (OMERACT RA magnetic resonance imaging scoring system (RAMRIS), grades 0-3), bone oedema in the metacarpal head and the phalangeal base (grades 0-3), and bone erosion in the metacarpal head and the phalangeal base (grades 0-3, and examples of higher grades). The presented reference images can be used to guide scoring of MCP joints according to the OMERACT RA MRI scoring system.
