We found that the cut-off point ADC value for differential diagnosis differed between mass and non-mass-like enhancement lesions and should be weighted in malignancy prediction. The optimized cutoff point ADC value for mass lesion is 1.0510-3mm2/s, which is lower than the NMLE where ADC=1.3510-3mm2/s and different than the benign and malignant without MRI types differentiation (ADC=1.2510-3mm2/s). This finding was different than the others studies whose ADC measurement was not affected by the lesion size.
