Comparison of apparent diffusion coefficient (ADC), fractional anisotropy (FA) and shear-wave velocity (SWV) values between malignant and benign tumours and between pleomorphic adenoma and adenolymphoma

Pathological diagnosis	ADC (10−3 mm2 s−1)	FA	SWV (m s−1)	n
Malignant tumour	0.82 ± 0.22	0.25 ± 0.07	2.94 ± 0.39	16
Benign tumour	1.04 ± 0.37a	0.20 ± 0.06a	2.09 ± 0.52b	35
Pleomorphic adenoma	1.13 ± 0.24	0.16 ± 0.03	2.43 ± 0.25	16
Adenolymphoma	0.80 ± 0.24c	0.24 ± 0.03d	1.72 ± 0.55d	15

Wilcoxon–Mann–Whitney test was used for statistical analysis.

^ap < 0.05, compared with malignancy.

^bp < 0.0001, compared with malignancy.

^cp < 0.01, compared with pleomorphic adenoma.

^dp < 0.001, compared with pleomorphic adenoma.
