Ultrasonography detection of early bone erosions in the metacarpophalangeal joints of patients with rheumatoid arthritis.

Abstract

US is at least as sensitive as MRI in detecting bone erosions in MCP and wrist joints. Since US examination is a more easily available and less expensive procedure than MRI, our findings justify its use as a diagnostic tool for early arthritis. In addition US may also be utilized in the follow up of patients with an established diagnosis of inflammatory arthritis.
