Abstract: 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 results were compared with those of 39 cases of mass-like breast carcer.The morphological characteristics,dynamic contrastenhanced 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 diagnosis.
