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.

材料与方法：搜集术前行乳腺MR检查并经穿刺或手术病理证实的236例乳腺病变，以对侧正常乳腺腺体作为正常对照，采用横轴位的平面回波-扩散加权成像序列，TR=8400ms，TE=93.8ms，层厚=4mm，激励次数=2：视野=30×30cm，矩阵=128×128，ASSET=2，b值=0和1000s/mm~2；参考动态增强图像准确定位，测量病变区和对侧正常乳腺腺体的ADC值，应用t检验比较良、恶性病变及正常腺体ADC值的差异，采用接收者工作特征曲线(receiver operating characteristic curve，ROC)确定良恶性病变的ADC界值；根据BI-RADS MRI将乳腺病变按照形态学表现分为肿块性病变和非肿块性病变两组，比较ADC值在肿块和非肿块性病变中定性诊断的效能。
