Materials and Methods:236 pathology-confirmed breast lesions(155 malignanty,81 benignancy) and 221 disease-free contralateral breast tissues were examined using EPI-DWIb values=0,1000 s/mm~2TR/TE=8400ms/93.8ms; FOV=30×30cm;matrix=128×128;ASSET=2,slice thickness=4mm.DCE-MR imaging was also performed for accurate location of the lesion using VIBRANT sequence.The mean ADC values of malignant and benign lesions and the disease-flee contralateral breast tissues were calculated from the ADC map for each patient.One-way analysis of variance was applied to compare the mean ADCs of malignant lesions with benign lesions and disease-flee contralateral breast tissues.The threshold ADC value for malignant lesion was determined using a receiver operating characteristic(ROC curve analysis.Each lesion was classified into two major types:mass and non-mass lesion.The diagnostic performance of DWI was compared in breast mass and non-mass lesions.Results:155 malignant and 81 benign lesions were confirmed in 236 lesions.
