【摘要】目的探讨乳腺癌的MRI征象和病理特征的关系.方法选取2014年2月至2016年2月在昆山市第一人民医院治疗的乳腺癌168例共180个病灶,分析MRI图像与病理类型及组织学分化程度关系,同时测量表观扩散系数(ADC)值.结果浸润性导管癌MRI表现为边缘有毛刺、边界模糊及内部有坏死的比例分别为57.69%、84.62%和55.13%,明显高于其他类型乳腺癌的16.67%、8.33%和16.67%,差异有统计学意义(P<0.05);组织学Ⅰ级病灶MRI表现为边缘无毛刺、边界清楚及内部无坏死的比例分别为76.47%、70.59%和94.12%,明显高于组织学Ⅱ级和Ⅲ级病灶的41.94%和36.36%、1.61%和27.27%、40.32%和36.63%,差异均有统计学意义(P<0.05);浸润性导管癌ADC值为(1.082±0.033)×10-3
mm2/s,明显低于其他类型乳腺癌(1.204±0.027)×10-3 mm2/s,差异有统计学意义(P<0.05);组织学Ⅲ级病灶ADC值为(1.012±0.030)×10-3 mm2/s,明显低于组织学Ⅰ级和Ⅱ级病灶[(1.153±0.061)×10-3 mm2/s、(1.147±0.041)×10-3 mm2/s],差异有统计学意义(P<0.05).结论乳腺癌MRI形态学特征以及ADC值为乳腺癌术前病理分型评估可能有参考价值.%Objective To investigate the relationship between magnetic resonance imaging (MRI) features and pathological features of breast cancer. Methods A total of 168 patients with breast cancer with 180 lesions, who admit-ted to our hospital from February 2014 to February 2016, were selected. The relationships between MRI and
pathologi-cal type and histological differentiation were analyzed, and the apparent diffusion coefficient (ADC) values were mea-sured. Results The proportion of edge burr, boundary blur and internal necrosis in MRI findings of invasive ductal car-cinoma were respectively 57.69%, 84.62% and 55.13%, which were significantly higher than 16.67%, 8.33% and
16.67%of other types of breast cancer (P<0.05). The proportion of no edge burr, clear boundary and no necrosis in MRI fea tures ofⅠgrade lesion of histology were respectively 76.47%, 70.59%and 94.12%, which were significantly higher than 41.94%, 1.61%and 40.32%of theⅡgrade lesion of histology and 36.36%, 27.27%and 36.63%ofⅢgrade lesion of histology (P<0.05). The ADC value of invasive ductal carcinoma was (1.082 ± 0.033) × 10-3 mm2/s, which was signifi-cantly lower than (1.204±0.027)×10-3 mm2/s of other types of breast cancer (P<0.05). The ADC value ofⅢgrade lesion of histology was (1.012±0.030)×10-3 mm2/s, which was significantly lower than (1.153±0.061)×10-3 mm2/s ofⅠgrade le-sion of histology and (1.147 ± 0.041) × 10-3 mm2/s ofⅡgrade lesion of histology (P<0.05). Conclusion The MRI mor-phological characteristics and ADC value of breast cancer can provide some help for the evaluation of preoperative path-ological types of breast cancer.
