| 摘 要： | 目的探讨MR扩散、灌注及动态增强成像在乳腺病变中的诊断价值。资料与方法80例乳腺病变患者行术前MR扩散、T2*W首过灌注及动态增强检查,回顾性分析乳腺病变MRI表现,分析比较扩散、灌注及动态增强的诊断价值。结果乳腺良、恶性病变表观扩散系数(ADC)值具有显著差异,诊断敏感性、特异性、准确性分别为80%、89.19%、79.38%;恶性病变T2*W首过灌注最大信号丢失率明显高于良性病变(P<0.05),诊断敏感性、特异性、准确性分别为81.82%、83.78%、82.61%;动态增强扫描诊断敏感性、特异性、准确性分别为76.36%、83.78%、79.35%;三者联合诊断敏感性、特异性、准确性分别为92.73%,91.89%、92.39%。结论乳腺MR扩散、灌注成像有助于乳腺良恶性病变的鉴别。 |

| Abstract: | Objective To evaluate the diagnostic value of diffusion weighted imaging,perfusion weighted imaging and dynamic contrast enhanced MRI in breast lesions.Materials and Methods Dynamic contrast-enhanced MRI,diffusion weighted imaging (DWI) and T2*weighted-first pass perfusion weighted imaging(PWI) of the breasts were performed in 80 female patients with suspected breast lesions before surgery. The MR imaging data were retrospectively analyzed. Using histological results as the gold standard,the diagnostic sens... |
