Reduced-FOV DWI (rFOV-DWI) of the pancreas has been applied in small cohorts and demonstrated improved image quality, but it has not been studied in the detection and characterization of insulioma. In this study, we compared the imaging quality (IQ) of rFOV-DWI and full FOV DWI sequence in insulioma detection. We also explored the correlation between the ADC value and WHO classification.
