[Abstract] Objective: To explore the relationship between the characteristic of breast cancer MRI and axillary lymph node metastasis, thus offering therapeutic schedule and prognosis in treating breast cancer.Materials and Methods: Forty-four cases of breast cancer were confirmed by pathology and preoperative MR scan, twenty-six cases of these patients were confirmed with ipsilateral axillary lymph node metastasis. Two experts read MRI image, and analyze the relationship between the ratio of different masses' short axis over long axis, dynamic enhanced MR features and the axillary lymph node metastasis of breast cancer.Results: (1) MR morphology analysis shows that the ratio of breast lumps' short axis over long axis has a negaive correlation with axillary lymphnode matastasis (t=5.892, P<0.05). (2) Edge reinforcement tumors' early intensive rate of breast cancer has positive correlation with axillary lymph node metastasis (t=3.966, P<0.01).Conclusion: The larger the ratio of breast lumps' short axis over long axis is, the smaller the possibility of axillary lymph node metastasis will be, the bigger edge reinforcement tumors' early intensive rate is, the greater the possibility of lymph node metastasis will be, and associated with poor prognosis. Therefore, axillary lymph node metastasis of breast cancer has good correlation with MR characteristic. MR examination can judge prognosis of breast cancer and axillary lymph node properties, then provide reference for effective treatment.
