Ultrasonography of major salivary glands: a highly specific tool for distinguishing primary Sjogren's syndrome from undifferentiated connective tissue diseases

摘要

Objectives. Recently, convincing data have been published on the value of salivary gland ultrasonography (SGUS) in differentiating primary SS from non-immune-mediated sicca syndrome. Limited data are available regarding the diagnostic accuracy of SGUS in distinguishing SS from other rheumatic diseases. The purpose of this study was to assess the usefulness of SGUS in distinguishing patients with SS from those with xerostomia and/ or xerophthalmia and a diagnosis of stable UCTD.
