Sonography can depict ultrastructural morphopathological features of an enthesis and its adjoining tissue structures, as well as increased vascularity; candidate entheses were proposed for an initial sonographic PsA enthesitis index. Ultrasound also can readily demonstrate soft tissue changes, synovitis, erosions, and osteoproliferation in dactylitis, and these features were proposed for an initial sonographic dactylitis index. A perspective was also presented on a wider proposed index including the skin, nail, joint, and enthesis. ER -
