METHODS: Twenty patients diagnosed with RA according to the ACR criteria were included in the study. All US examinations were performed bilaterally by two investigators (with different experience in the field of musculoskeletal US) at the following sites: the dorsal, lateral and volar aspect of the second metacarpal, ulnar and fifth metatarsal head; and the dorsal and volar aspect of the third metacarpal and second proximal heads. Each quadrant was scanning in longitudinal and transverse scans for assessing the qualitative, semiquantitative and quantitative US findings indicative of bone erosions according the OMERACT preliminary definition. RESULTS: Both κ-values and overall agreement percentages of qualitative and semiquantitative assessments showed moderate to excellent agreement between the two investigators. Similar results were obtained for the quantitative assessment with the concordance correlation coefficient value always significant. The only exception was the volar aspects, in particular those of the fifth metatarsal head. CONCLUSION: Our study suggests that after a 4-week dedicated training programme, a rheumatologist without experience in US is able to detect and score bone erosions in the hands and feet of patients with RA.
