Abstract The objective of the study was with multidetector computed tomography CT as the reference method to determine whether bone erosions in rheumatoid arthritis RA metacarpophalangeal MCP joints detected with magnetic resonance imaging MRI and ultrasonography US but not with radiography represent true erosive changes. We included 17 RA patients with at least one previously detected radiographically invisible MCP joint MRI erosion and four healthy control individuals. They all underwent CT MRI US and radiography of the 2nd to 5th MCP joints of one hand on the same day. Each imaging modality was evaluated for the presence of bone erosions in each MCP .
