摘要
目的:探讨乳腺非肿块型癌与肿块型癌的MRI表现的差异。方法:回顾性分析经病理证实的31例乳腺非肿块型癌及39例肿块型癌,比较两者的形态学特点、动态增强血流动力学特点、ADC值等。结果:乳腺非肿块型癌呈区域性(68%)及段样强化(32%)为主,病变内部呈不均匀强化及簇状强化为主(各占39%及45%),乳腺肿块型癌以不均匀强化、环形强化及肿块伴周围多发结节强化为主。非肿块型乳腺癌的TIC类型呈Ⅱ型平台型(51.6%)为主,与肿块型乳腺癌的TIC类型差异有统计学意义。乳腺非肿块型癌的ADC值为(1.153±0.325)×10^(-3) mm^2/s,与乳腺肿块型癌的ADC值差异有统计学意义(P<0.05)。结论:乳腺非肿块型癌与肿块型癌的MR形态学、血流动力学特点及ADC值存在差异,对其诊断及鉴别诊断有帮助。
Objective：To analyze the difference of MRI manifestations of non-mass-like breast cancer and mass-like carcer. Methods： 31 cases of non-mass-like breast cancer confirmed by pathology were analyzed retrospectively, and the re- sults were compared with those of 39 cases of mass-like breast carcer. The morphological characteristics,dynamic contrast- enhanced characteristics and ADC value of the two groups were compared. Results： Non-mass-like breast carcinoma showed regional （68 % ） and segmental （32%） contrast enhancement, heterogeneously （39 % ） or in clusters （45 % ）. The mass-like breast cancer mainly showed heterogeneous enhancement, ring enhancement and mass with multiple enhanced nodules. Of the 31 non-mass-like breast carcinoma, 51.6% showed TIC type II with significant difference from that of mass-like breast carcinoma. The ADC values of non-mass-like breast carcinoma （1. 153 ±0. 325） ×10^-3 mm2/s were significantly different from that of mass-like breast carcinoma （P〈0.05）. There was statistical significant difference in ADC values between the two types of breast carcinoma. Conclusion： There were significant differences in MR morphology, hemodynamics and ADC value between non-mass-like breast cancer and mass-like breast cancer, these are helpful for the diagnosis and differential di- agnosis.
