Six-joint ultrasound in rheumatoid arthritis: a feasible approach for implementing ultrasound in remission.

OBJECTIVES: Subclinical disease activity in rheumatoid arthritis (RA) detected by imaging methods is predictive for flares and damage. Lack of time is the major limitation for not screening for subclinical disease in routine practice. We aimed to determine the most feasible protocol to screen patients with no clinical disease activity by ultrasound (US). METHODS: A hundred consecutive RA patients with no clinical activity according to the...
