Using ultrasonography to diagnose Sjögren's syndrome.

Ultrasonographic imaging of the parotid gland parenchyma represents a relatively new and extremely useful procedure that was applied in this study of patients with secondary Sjögren's syndrome, or SS. A nonhomogeneous parotid gland and hypoechoic areas were apparent in the sonograms of nine consecutive SS patients who were examined using this simple, noninvasive technique.
