BI-RADS is an acronym for Breast Imaging-Reporting and Data System, a quality assurance tool originally designed for use with mammography. The system is a. utilizada en el BIRADS ya es ampliamente conocida, aún siguen utilizándose términos que no son usados en la clasificación y las categorías a veces son. BI-RADS classification is proposed by the American College of Radiology (ACR), last updated in November , and is a widely used classification system at.

Follow up after breast conservative surgery Involuting, calcified fibroadenomas Multiple large, rod-like calcifications Intramammary lymph nodes Vascular calcifications Implants Architectural distortion clearly related to prior surgery. Alone it kamografia little specificity. The assessment categories were developed for mammography and later adapted for use with MRI and Ultrasound findings.

By subdividing Category 4 into 4A, 4B and 4Cit is encouraged that relevant probabilities for malignancy be indicated within this category so the patient and her physician can make an informed decision on the ultimate course of action.

They are clasigicacion thing to not care about, unless you are a radiologist.

We will first discuss the breast imaging lexicon of mammography and ultrasound and then discuss in more detail the final assessment categories and the do’s and don’ts in these categories. When additional imaging studies are completed, a final assessment is made.

Location and size should be applied in any lesion, that must undergo biopsy. Don’t forget to mention in the report that the biraes node on US corresponds with the noncalcified mass on mammography. Special cases – cases with a unique diagnosis or pathognomonic ultrasound appearance:.


These findings may have associated features, like for instance a mass can be accompanied with skin thickening, nipple retraction, calcifications etc. Do realize, that a benign evaluation may always be rendered mamografoa completion of the Category 3 analysis, if in the opinion of the radiologist the finding has no chance of malignancy and thus is Category 2. This category is reserved for findings that do not have the classic appearance of malignancy but are sufficiently suspicious to justify a recommendation for biopsy.

In the version the approach has changed. Architectural distortion and Asymmetries Approximation of its greatest linear dimension. Journal of Digital Imaging.

After chemotherapy the tumor is not visible on the mammogram. Ultrasound of the region demonstrated an irregular mass, which proved to be an adenocarcinoma with fine needle aspiration FNA. Verbal discussions between radiologist, patient or referring clinician should be documented in the report. Like BI-RADS 1, this is a normal assessment, but here, the interpreter chooses to describe a benign finding in the mammography report, like:.

BI-RADS classifications have also helped in monitoring breast cancer treatment and supporting breast cancer research again by making statistics easier to calculate. Always make sure that a mass that is found on physical examination is the same as the mass that is found with mammography or ultrasound. Category 6 indicates a known cancer, proven by biopsy. The table shows a summary of the mammography and ultrasound lexicon.

Compare to previous studies. Examples of reporting Indication for examination Painful mobile lump, lateral in right breast. The use of the term “density” is confusing, as the term “density” should only be used to describe the x-ray attenuation of a mass compared to an equal volume of fibroglandular tissue. Describe any significant finding using standardized terminology.


Concordant with the lump and the mass on the mammogram there is an oval simple cyst, parallel orientation, circumscribed, Anechoic with posterior enhancement. This implies a suspicious finding. The mass is equal dense compared to the fibroglandular tissue.

Most biopsies today are done with a needle ibrads local anesthetic and are painless. Here an example of global asymmetry. Verbal discussions between radiologist, patient and referring clinician should be documented in the original report or in an addendum. Posterior features represent the attenuation characteristics of a mass with respect to its acoustic transmission, also of additional value.

The benefit of BI-RADS to radiologists is that it forces them to think about which category their findings will fit into and when they assign each case a category it then becomes possible to calculate accuracy statistics.

Then use category 2 and add sentence stating the absence of mammographic correlate for the pathology. However in the right breast a group of amorphous and fine pleomorphic calcifications was seen.

Some areas in the breasts are sufficiently dense to obscure small masses. Indication for examination Referral from general practitioner. Stuff, is junk we keep.
