Ultrasound in systemic sclerosis. A multi-target approach from joint to lung.

Ultrasound (US) is a cost-effective, noninvasive, accessible imaging modality that clinicians use at the point of care to assess disease activity and therapeutic efficacy in different rheumatic conditions. However, its utility has been prevalently demonstrated in the field of chronic arthritides. Only in the last few years there was an interest to explore the potential of US beyond the musculoskeletal area. In this way, preliminary US data about the assessment of the different targets involved in systemic sclerosis such as joints, tendons, skin, vessels, and lung have been provided. The main purpose of this US review is to provide an overview of the potential role of US in the multi-target assessment of SSc and to discuss the current evidence supporting its relevance and applications in daily clinical practice.
