目的：分析三阴性乳腺癌(triple-negative breast cancer,TNBC)及 HER-2过表达型乳腺癌 MRI 动态增强特征及 ADC值,提高对两者 MRI特征的认识。方法对入组三阴性乳腺癌与 HER-2过表达乳腺癌患者的 MRI动态增强图像进行分析,测量ADC值,进行统计学比较。结果 TNBC与 HER-2过表达型乳腺癌病灶形状、边缘、强化方式及 ADC 值之间差异有显著性(P<0.05)；而年龄、是否肿块、病灶类别及时间-信号曲线(time signal intensity curve,TIC)无统计学意义(P>0.05)。结论 MRI动态增强特征(病灶形状、边缘、强化方式)与 ADC值对鉴别TNBC及 HER-2过表达型乳腺癌有意义。
目的：分析三陰性乳腺癌(triple-negative breast cancer,TNBC)及 HER-2過錶達型乳腺癌 MRI 動態增彊特徵及 ADC值,提高對兩者 MRI特徵的認識。方法對入組三陰性乳腺癌與 HER-2過錶達乳腺癌患者的 MRI動態增彊圖像進行分析,測量ADC值,進行統計學比較。結果 TNBC與 HER-2過錶達型乳腺癌病竈形狀、邊緣、彊化方式及 ADC 值之間差異有顯著性(P<0.05)；而年齡、是否腫塊、病竈類彆及時間-信號麯線(time signal intensity curve,TIC)無統計學意義(P>0.05)。結論 MRI動態增彊特徵(病竈形狀、邊緣、彊化方式)與 ADC值對鑒彆TNBC及 HER-2過錶達型乳腺癌有意義。

Objective To analyze the DCE-MRI features and ADC value in triple-negative breast cancer and HER-2 overexpres-sion breast cancer,and to improve the j udgment of both characteristic in MRI.Methods To analyse the DCE-MRI imaging of TNBC and HER-2 overexpression breast cancer,measured the ADC value and compared the statistics.Results Compared with the shape, margin,the way of enhancement and ADC value of the TNBC and HER-2 overexpression breast cancer,the distinction has statisti-cally significant(P<0.05);there were no statistically significant difference among age,mass or nomass,categories of lesions and TIC,(P>0.05).Conclusion DCE-MRI features of the shape,margin,the way of enhancement and ADC values were useful for the diagnosis of TNBC and HER-2 overexpression breast cancer.
