title: [Clinical usefulness of salivary gland ultrasonography in Sjögren's syndrome: Where are we now?].
abstract: Salivary gland ultrasonography is a simple, noninvasive and inexpensive procedure, which provides valuable information for the diagnosis of primary Sjögren's syndrome (pSS). The main sonographic characteristic of the major salivary glands (parotid and submandibular) in pSS patients is the heterogeneity of the parenchyma, with the appearance of hypoechoic areas. Numerous studies published over the past 20 years report a sensitivity of 70% and a specificity of more than 90% for the diagnosis of pSS. Before the widespread use of this procedure in daily practice and its integration into classification criteria of the disease, it has yet to be validated in terms of reproducibility and a consensus score should be established. This work is being conducted by an international group of experts. Other ultrasound techniques such as elastography could also be of interest to objectively quantify changes in the glandular tissue that occur during the disease.
