Added Value of Parotid R2* Values for Evaluation of Sjögren Syndrome: A Preliminary Study

Objective: To explore the application of parotid R2* values for evaluating Sjögren syndrome (SS). Methods: Twenty-four consecutive SS patients and 24 sex-matched and age-matched healthy volunteers underwent bilateral parotid 3.0 T magnetic resonance (MR) imaging, including blood oxygenation level dependent sequence. Parotid R2* values of SS patients and volunteers were compared. A receiver operating characteristic analysis was used to evaluate the diagnostic performance of parotid R2* value alone and in combination with MR nodular grade. Results: The left parotid R2* value was significantly lower than the right (P = 0.006) in SS patients. Parotid R2* value in SS patients was significantly lower than that in healthy volunteers (P
