ADC, apparent diffusion coefficient.; IQR, Interquartile Range; SD, standard deviation.

indicate p < 0.05 when compared with pleomorphic adenomas.

indicate p < 0.05 when compared with Warthin tumors.

indicate the data are consistent with normal distribution and homogeneity of variance are presented as mean ± SD; the other data are presented as median ± IQR.
