In this study we aimed to investigate the apparent diffusion coefficient (ADC) of head and neck neoplasm focusing in the nasopharnx, oropharynx and oral tongue using PROPLLER-DWI. Our results show that PROPELLER-DWI is immune from geographic distortion and signal mis-registration in all patients. The ADC of neoplasm is significantly lower than the normal tissue and inflammatory lesions.
