Assessment of peripheral enthesitis in the spondylarthropathies by ultrasonography combined with power Doppler: A cross‐sectional study

Abstract

US in B mode combined with power Doppler allowed the detection of peripheral enthesitis in a majority of SpA patients, but not in MBP or RA patients. The presence of entheseal involvement was independent of SpA subtype, but its degree of severity appeared to be greater in peripheral forms. US could be very useful for both the diagnosis and the assessment of SpA activity.
