Breast cancer has become the world's leading female cancer mortality rate. The clinical treatment methods for breast cancer patients are mainly surgical treatment and targeted treatment. The preoperative axillary lymph node metastasis of breast cancer is an important factor affecting the treatment and prognosis of breast cancer patients. With the rapid development of magnetic resonance imaging technology,researchers not only evaluate axillary lymph node metastasis based on conventional imaging features such as size,edge morphology,and cortical thickness,but also use functional imaging methods to understand the microstructure information of lymph nodes and quantitatively evaluate lymph node heterogeneity. In addition,emerging imaging omics,imaging combined with artificial intelligence can obtain more parameters and have achieved more in-depth research results in the study of axillary lymph nodes. This article reviews the research progress of preoperative magnetic resonance imaging in axillary lymph node metastasis in breast cancer,aiming to summarize the advantages and disadvantages of each imaging sequence in the application of axillary lymph node metastasis in breast cancer,and provide a new direction for subsequent imaging science research.
