Purpose: To investigate the feasibility of using diffusion-weighted (DW) echo-planar imaging (EPI) for measuring different functional conditions of the parotid gland and to compare different field strengths. Methods: Parotid glands of 27 healthy volunteers were examined with a DW EPI sequence before and after oral stimulation with commercially available lemon juice using 1.5T and 3T. The b factors used were 0, 500, and 1,000s/mm2. ADC maps were evaluated with a manually placed ROI including the entire parotid gland placed on either side. For comparison of results, the Student's t test was used, based on the medi…
