Recent studies have reported that lipid infiltration (LIPG) may be one of the mechanisms of salivary secretion decrease in diabetic patients. In this study, we compared the difference of ADCs between normal and patients before and after stimulation. It demonstrated that diffusion-weighted echo-planar MR imaging allows non-invasive quantification of functional changes in the parotid glands and the feasibility in reflecting the degree of fat deposition in parotid gland caused by parotid dysfunction.
