Breast imaging reporting and data system (BIRDS), which is categorized into mammography and breast MRI. Common mammographic signs include typical signs (mass, calcification, structural distortion) and characteristic signs (ductal signs, intramammary lymph nodes, mass asymmetry, focal asymmetry, nipple, skin, and mesenchymal changes), with emphasis on mammographic signs of calcification. Calcifications were categorized as typical benign calcifications, intermediate calcifications, and highly malignant possible calcifications. Overall assessment of the mammogram BI-RADS grading report: (Incomplete assessment) Grade 0: Recall is needed and reassessment in conjunction with other tests. Indicates that the information obtained from the examination may be incomplete. (Complete assessment) Grade I: No abnormality is seen. grade II: Benign changes are considered and regular follow-up (e.g., annually) is recommended. grade III: Benign disease is possible, but shorter follow-up intervals (e.g., once every 3 to 6 months) are needed. The percentage of malignancy at this level is less than 2%.Grade IV: Abnormalities are present and the possibility of malignant disease cannot be completely excluded, requiring biopsy for clarification.Grade IVa: Tendency to have a low likelihood of malignancy.Grade IVb: Tendency to have a moderate likelihood of malignancy.Grade IVc: Tendency to have a high likelihood of malignancy.Grade V: Highly suspicious of malignant lesions (almost identified as malignant disease), requiring surgical excisional biopsy.Grade VI: Already pathologically confirmed to be a Grade VI: already confirmed by pathology as a malignant lesion. With the widespread popularization of breast MRI, MRI BI-RADS has also emerged, but due to its high cost, it is not as widely used as X-ray, and its specificity can be improved by combining it with X-ray molybdenum target radiography. Overall assessment of BI-RADS grading of breast MRI: Grade 0 – further imaging evaluation is needed/pre-imaging comparison is needed (incomplete assessment); Complete assessment: Grade I – negative; Grade II – benign findings; Grade III – possibly benign findings, short-term follow up is recommended; Grade IV – suspicious abnormality, biopsy is to be considered; Grade V – malignancy is highly suspected, appropriate clinical measures are to be taken; Grade VI – biopsy has been performed, appropriate clinical measures are to be taken; Grade VI – malignancy is highly suspected, biopsy has been performed, appropriate clinical measures are to be taken; Grade V is highly suspected, biopsy has been performed, appropriate clinical measures are to be taken; Grade VI – malignancy has been performed, biopsy has been performed. Grade VI – biopsy confirmed malignancy, appropriate measures should be taken. At present, breast MRI examination is mainly used for: 1, pre-surgical staging 2, searching for primary foci for those with positive axillary lymph nodes 3, evaluation of neoadjuvant chemotherapy 4, application of breast-conserving surgery 5, screening of high-risk groups 6, evaluation of prosthesis 7, MR-guided localization and biopsy. Our Imaging Center is currently equipped with advanced MRI machines and the soon to be installed fully digital breast flat panel mammography (DR), which plays a great role in the screening, diagnosis and evaluation of chemotherapy effect of breast cancer in our Department of Breast Disease, which is conducive to the early diagnosis and improves the accuracy of diagnosis.
