Correlation between colour Doppler activity and parenchymal alterations in salivary glands of patients with primary Sjögren's disease

Colour Doppler ultrasonography reflects inflammatory vascular changes paralleling structural and clinical disease activity in SjD. Although it does not yet provide independent diagnostic value, further studies are needed to define the role of Colour Doppler as a complementary tool in salivary gland ultrasonography for assessing glandular inflammation and lymphoproliferative risk.
