Open Access Abstract The aim of this study was to demonstrate the ability of conventional radiography to detect bone erosions of different sizes in metacarpophalangeal MCP joints of rheumatoid arthritis RA patients using magnetic resonance imaging MRI as the standard reference. A T Esaote dedicated extremity MRI unit was used to obtain axial and coronal T1-weighted gradient echo images of the dominant 2nd to 5th MCP joints of 69 RA .
