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.
