Diagnostic performance of <scp>MR</scp> imaging of three major salivary glands for Sjögren's syndrome

Abstract

The presence of multiple high-signal-intensity spots on an MR sialogram in the parotid gland should be considered the best diagnostic indicator for Sjögren's syndrome. The presence of spots, heterogeneity, and the change to smaller volumes in the submandibular gland were also helpful because of their high specificity, particularly in advanced cases.
