In this study we aimed to verify the imaging quality of fast spin-echo PROPELLER diffusion weighted imaging (FSE-PROP-DWI) and echoplanar DWI (EP-DWI) in oral cavity and to investigate the apparent diffusion coefficient (ADC) of pathological proven oral tongue squamous cell carcinoma (OTSCC). Our results show that FSE-PROP-DWI is superior to EP-DWI with less imaging distortion and is satisfactory for measurement of ADC of OTSCC.
