摘　　要：目的:评价3.0 T磁共振功能成像在乳腺癌诊断中的应用价值。方法:回顾性分析21例穿刺活检或手术病理证实为乳腺癌的MRI功能成像特征。结果:21例乳腺癌患者中,共检出21个病灶,15例伴腋窝淋巴结转移,3例病灶累及胸肌;病理结果:浸润性导管癌19例,黏液癌1例,浸润性小叶癌1例;病灶边界不清,可见分叶和毛刺征象,T1WI呈稍低、等信号,T2WI+FS呈稍高、高信号,DWI均为高信号,ADC值为(0.90±0.23)×10-3;动态增强的时间-信号强度曲线,4例呈"流出型"Ⅲ型曲线,17例呈"平台型"Ⅱ型曲线。结论:3.0T磁共振功能成像对乳腺癌的诊断,尤其病灶数目、大小,胸肌累及、腋窝淋巴结转移有重要价值。Objective：To evaluate the application value of magnetic resonance imaging（MRI）3.0 T in the diagnosis of breast cancer. Method：Retrospective analysis was used on the MRI imaging characteristics of 21 patients with breast cancer confirmed by biopsy or surgical pathology.Result：Among the 21 cases,a total of 21 lesions were found out：15 cases of axillary lymph node metastasis（ALNM）,and 3 cases with involvement of pectoralis muscle;for pathological results：invasive ductal carcinoma was found in 19 cases,mucinous carcinoma in 1 case and invasive lobular carcinoma in 1 case;the boundary of the lesion was not clear,lobulation and speculation can be seen;T1WI was slightly lower with isointensity,T2WI＋FS was slightly higher with high intensity,while DWI were all with high intensity;ADC value was in the range of（0.90± 0.23）× 10^-3,showed dynamically enhanced time-intensity curve;4 cases showed curve of type Ⅲ known as outflow curve,17 cases showed of curve of type Ⅱ known as platform curve. Conclusion：MRI 3.0 T has important value in assessment of tumor size,number,involvement of pectoralis muscle,and ALNM so as to diagnose the breast cancer.
