Abstract:
Objective To investigate the relationship of dynamic enhanced MRI findings of breast cancer and axillary lymph node metastasis. Methods Clinical and dynamic MRI data of 79 patients with breast cancer (31 with and 48 without axillary lymph node metastasis) were retrospectively analyzed. MRI findings of the lesions were systematically described according to breast imaging reporting and data system (BI-RADS) standards. Then the relationship of MRI findings and axillary lymph node metastasis were analyzed. Results MRI showed mass-like lesions in 71 cases (71/79, 89.87%), among them axillary lymph node metastasis was pathologically proved in 27 cases. There were significant differences in location of lesions between patients with or without metastasis axillary lymph node metastasis (P<0.05), while no significant difference in types of lesions was detected (P>0.05). There were significant differences in the marginal morphology, early enhancement pattern and mass maximum diameter of mass-like lesions between patients with or without axillary lymph node metastasis (all P<0.05), whereas no significant difference of lesion shape, internal enhancement mode nor delay phase time-signal intensity curve type was observed (all P>0.05). Conclusion The lesion's location, size of mass, marginal features and early enhancement patterns showed on dynamic enhanced MRI are associated with axillary lymph node metastasis of breast cancer.
