Examples on OMERACT SGUS scoring system.
(A) Ultrasound images of parotid glands and (B) submandibular glands affected by pSS. Grade 0: Normal parenchyma, grade 1: Minimal change, mild inhomogeneity without anechoic/hypoechoic areas, grade 2: Moderate change, moderate inhomogeneity with focal anechoic/hypoechoic areas, grade 3: Severe change, diffuse inhomogeneity with anechoic/hypoechoic areas occupying the entire gland surface.
