BI-RADS (Mammogram Reporting and Data System) Hierarchical Interpretation

Many patients have completed breast-related examination, for the report list on the BI-RADS rating do not understand, today we will briefyouBI-RADS (Mammograms Reporting and Data System) is divided into 0 to 6 levels, and is nowinterpretationon the specific situation0 level: incomplete information, need to be re-evaluated in conjunction with other examinations (clinical signs, ultrasound tests without signs)level 1: (negative) no abnormal detection, routine physical examination is recommended (1 in 1 year)Ultrasound examination no abnormality: breast ultrasound shows the breast structure is clear, no lumps, no skin thickening, no microcalcification, etc, if found intherean lymph nodes, pre-arm lymph nodes, but the lymph node sydage shape is not abnormal, showing lymph nodes, are considered normal lymph nodes, also belong to level 1Level 2: Benign lesionsRegular follow-up (retest 1 time in 6 months to 1 year); including: breast benign lumps (simple cysts, lactocysms, fibroids without change after follow-up, fibrous adenomas, lipomas); positive benign calcification (ring calcification, short strip calcification with clear boundaries, Large, speckled calcification, sparse size than a single dot-shaped calcification, crescent-shaped sedimentary calcification; breast catalysis implantation; if clinical and lumps, and there are limited asymmetries, although the finaldiagnosedfor sclerosing adenoids, should also be classified as level 3 or 4A3 levels: great probability of benign (malignancy rate of 2%), recommended short-term follow-up, (1 time in March-June)(1) age 40 years old, lump form is circular or oval; (2) parallel or horizontal ratio to the skin (i.ewidth) ;(3) The boundary is clear; (4) the perimeter (with the surrounding tissue's moving band or area) is narrow and sharp; (5) the rear echo is enhanced or unchanged; (6) there is no change in the surrounding tissue; (7) the larger (-0.5mm) calcification; and (8) there is no blood flow insideWhere articles 1 and 2 are in conformity, plus 3 or more are at level 3 level 4: for nature to be determined (3%-94% of the probability of malignancy, a puncture biopsy needs to be considered for a definitive diagnosis) It can be further divided into: 4a (possibly malignant 3-30%), 4b (possibly malignant 31-70%), 4c (may be malignant 71-94%) 4a: Low-level suspected malignant lesions: including touchable, partially marginally clear solid lumps (fibroids, complex cysts, or suspected abscesses) 4b: Moderate lysis Partially soaked lumps or fat necrosis The mastectoma requires a biopsy to be diagnosed 4c: The likelihood of malignant lesions is high Irregular morphological, marginal-soaked solid lumps and cluster-like clustercalization 5 levels: highly suspicious malignant (almost identified as breast cancer , i.e 95% of the malignant possibility), to do clinical treatment (1) morphological irregularities; (2) not parallel to the skin, cross-section al-1 (i.e width) ;(3) boundary unclear (fuzzy, tiny leaf, angled and (or) burr) ;(4) the appearance of strong echo esquire around; (5) the strong echo of the surrounding side; The edges are not sharp or irregular, the rear sound shadows are (6) the surrounding tissue changes (Cooper's ligaments straighten edifying and thickening, normal structural layering breaks or disappearances, skin thickening or depression) ;(7) tiny (less than 0.5mm) calcification; (8) there is blood flow inside Those who meet 3 or 3 of the 8 articles are level 5 and those who do not meet the conditions of 2, 3 or 5 are level 4 6: Pathology has been confirmed as malignant lesions, but has not yet undergone surgical excision, chemotherapy, or full mastectomy Do pre-treatment evaluation Medical Center Wang Xiaoyan Source:
