Analysis of malignancy signs in breast magnetic resonance imaging.

Background: To analyse the signs of malignant tumours in breast magnetic resonance imaging (MRI) and further improve the imaging diagnosis level of malignant breast tumours. Materials and Methods: The plain and enhanced MRI data of 60 patients who visited our hospital between January 2011 and January 2021 were analysed retrospectively, with 118 lesions in total. Malignant breast tumour signs were assessed. Results: A total of 96 lesions were pathologically confirmed as breast cancer, with 76 cases of single breast and single lesion, 10 cases of double breast and single lesion, 6 cases of single breast and two lesions, and 4 cases of single breast and three lesions. Regarding morphology, 58 lesions were regular in appearance and 60 were irregular, of which 50 had a burr sign or sharp angle sign. Strengthening methods included 52 cases of homogeneous strengthening, 3 of annular strengthening and 2 of cluster strengthening. Conclusion: A burr margin, local skin thickening, depression, adhesion and axillary lymph node enlargement are reliable MRI signs of breast cancer. When combined with Breast Imaging Reporting and Data System grading, these signs can effectively differentiate between benign and malignant breast tumours and constitute a key reference value for the diagnosis of breast cancer.
