There was a substantial crossover from initial nonoperative treatment to surgery after 3 months (25% of nonoperative patients), and these patients were included in the nonoperative group for analysis. A 10-year as-treated analysis was performed that showed no signicant differences between the two as-treated groups, with the exception of greater improvement on the Roland score for the surgical group. This suggests that the benet of surgery was not underestimated by including patients who underwent surgery beyond 3 months in the nonoperative group.

最初选择非手术治疗的患者有较大一部分（25%非手术治疗的患者）3个月后变换治疗方式，进行手术治疗，这些患者仍被归入非手术组进行分析。10年时进行的接受治疗分析显示，除了手术组Roland等级有较大的改善外，两个接受治疗组的差异没有统计学意义，这表明非手术组的患者3个月后进行手术治疗没有低估手术的效力。

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。
