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.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n The left parotid R2* value was significantly lower than the right (P<\/jats:italic> = 0.006) in SS patients. Parotid R2* value in SS patients was significantly lower than that in healthy volunteers (P<\/jats:italic> < 0.001). With a cutoff value of 64.14\/s, the sensitivity of the parotid R2* value was 62.5% in the diagnosis of SS.
