This retrospective study evaluated the diagnostic efficacy of diffusion-weighted imaging (DWI) and amide proton transfer-weighted (APTw), for differentiating between malignant, pleomophic adenomas and Warthin’s tumours. APTw imaging can differentiate Warthin’s tumors and malignant tumors of parotid. ADC can differentiate Warthin’s tumors and pleomorphic adenomas. APT combined with ADC had the better performance to differentiate the three common kinds of parotid tumours.
