Observational study for assessing disease activity with quantitative joint power Doppler ultrasonography in patient with rheumatoid arthritis - Assessment of disease activity with quantitative joint power Doppler ultrasonography in patient with rheumatoid arthritis

Result: Clinical composite scores for rheumatoid activity were significantly decreased from baseline to 8th week, being sustained at a low level by biologic agents during the observational period. MCP and PIP joints with positive synovial vascularity after 8th week showed more subsequent joint damage progression than joints without synovial vascularity throughout the follow-up.
