Radiographic assessment in rheumatoid arthritis: From daily practice to clinical trials

Imaging evaluation in rheumatoid arthritis (RA) has evolved significantly in last decades. Even if the modern imaging technics like ultrasound and magnetic resonance imaging have unequivocal place in the assessment of early disease (especially for synovial inflammation, bone oedema, erosions), radiographic evaluation of hands and feet is still the most widely used imaging technic for quantification of joint damage in RA. In the current review we aim to address some practical issues related to the radiographic evaluation in RA from daily practice perspective, followed by a broader approach from the clinical trials point of view.
