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。
