Abstract

Ultrasound is a promising tool for assessment of rheumatoid arthritis patients. While acceptable ultrasound assessment was previously confined to large joints, high-frequency linear array transducers now allow high-resolution imaging of superficially located structures such as the joints of the hands and feet. Ultrasound has a particular advantage over magnetic resonance imaging in that an experienced observer can rapidly screen several joints for erosions in a relatively short time. Further data regarding important methodological and measurement issues must be obtained before ultrasound gains wider acceptance.
