Recent improvements in high frequency transducers and digital imaging proce
ssing have dramatically improved the quality of ultrasound images of superf
icial structures. This article describes the current role of ultrasound in
the management of inflammatory disease with respect to diagnosis, prognosti
cation, and intervention. It discusses the value of ultrasound in detection
of synovitis, bony erosions, enthesopathy and tendon disease as well as de
scribing the sonographic features of specific inflammatory disease entities
. It also describes potential roles of color and power Doppler imaging.
