Erosions in the wrist of a rheumatoid arthritis patient. Wrist of a rheumatoid arthritis patient visualised by (a, b) computed tomography and (c, d) T1-weighted magnetic resonance imaging in the (a, c) coronal and (b, d) axial planes. A bone erosion at the distal radius is seen on both computed tomography and magnetic resonance images in two planes (white arrows), but not on the corresponding radiograph (e). The erosion was assigned an OMERACT erosion score of 1 on both computed tomography and magnetic resonance imaging.
