Is sonoelastography a helpful method of evaluation to diagnose Sjögren's syndrome?

Objective: A new sonoelastography technique - virtual touch tissue quantification of acoustic radiation force impulses (ARFI) - offers a promising method for measuring tissue rigidity. The aim of this study was to assess the usefulness of ARFI for diagnosing Sjögren's syndrome (SS).

Methods: This transversal prospective study included 41 patients with SS according to American-European Consensus Group (AECG) criteria, and a control group without symptoms.
