Fig. 1

Representative images of a 57-year-old woman with pleomorphic adenoma (a–d), a 56-year-old man with Warthin’s tumor (e–h) and a 43-year-old woman with mucoepidermoid carcinoma (i–l). The left column was the axial T2-weighted image with fat suppression (a, e, i), the middle column was the axial T1-weighted enhancement image (b, f, j). After the ROIs were placed (c, g, k), corresponding histogram maps showed a high value MRE of pleomorphic adenoma (d), a low WOR value of Warthin’s tumor (h), and a high value TTP of mucoepidermoid carcinoma (l)
