Doppler sonography in assessing disease activity in rheumatoid arthritis.

Abstract The purpose of this study was to evaluate the use of spectral Doppler in the assessment of patients with rheumatoid arthritis (RA). The study group consisted of 32 patients with RA followed up clinically and by ultrasound using the resistive index (RI) measurements in the patients’ wrists as indicator of inflammation. Lower RI values were recorded at baseline compared with data derived at 1-y follow-up examination from patients in remission and normal controls (p
