Relationship of dynamic enhanced MRI findings of breast cancer and axillary lymph node metastasis / 中国医学影像技术

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 (P0.05). 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 P0.05). 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.
