This study compared the preoperative noninvasive prediction of axillary lymph node metastasis in patients with invasive breast cancer using radiomics derived from single and multi-sequence MRI. The combined radiomics model outperformed the single-sequence models, with the DCE model performing better among the single-sequence models. The combined MRI model achieved the highest performance, improving diagnostic accuracy and showing potential for prognostic prediction.

This study represents comprehensive analysis of metastasis' anatomical distribution and prognosis in breast cancer, offering invaluable insights into metastatic tendencies and characteristics.
