The Utility of Major Salivary Gland Ultrasonographic Parameters in the Diagnosis of Sjögren Syndrome.

Objective: To investigate ultrasonographically the salivary glands and to correlate ultrasonographic parameters with focus score, serum beta-2-microglobulin, and stimulated salivary flow rate.

Material And Methods: 32 patients with primary Sjögren's syndrome (pSS) and 32 healthy controls were enrolled in this case-control study, performed in the Department of Internal Medicine, Division of Rheumatology, "Victor Babeș" University of Medicine and Pharmacy, Timișoara, Romania. All the patients and controls were examined by salivary gland ultrasonography (B-mode, color and spectral Doppler, and sonoelastography), determining the following parameters: salivary gland ultrasonography (SGUS) score, resistive index (RI) of transverse facial artery, and shear wave velocity (SWV).
