The value of joint ultrasonography in predicting arthritis in seropositive patients with arthralgia: a prospective cohort study

摘要

BackgroundThe value of joint ultrasonography (US) in the prediction of clinical arthritis in individuals at risk of developing rheumatoid arthritis (RA) is still a point of debate, due to varying scanning protocols and different populations. We investigated whether US abnormalities assessed with a standard joint protocol can predict development of arthritis in seropositive patients with arthralgia.
