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.

Don’t use for imaging findings, demonstrating suspicious findings other than the known cancer, then use Category 4 or 5. Like BI-RADS 1, this is a normal assessment, but here, the interpreter chooses to describe a benign finding in the mammography report, like:.

This microcalcification is round but the edges are not sharply defined. Views Read Edit View history. Examples of reporting Indication for examination Painful mobile lump, lateral in right breast.

Nevertheless the patient and the clinician preferred removal, because the radiologist was not able to present a clear differential diagnosis. Mammography is highly sensitive in this setting.

In the atlas calcifications were classified by morphology and distribution either as benign, intermediate concern or high probability of malignancy. Since calcifications of intermediate concern and of high probability of malignancy all are being treated the same way, which usually means biopsy, it is logic to group them together.

Coarse heterogeneous BI-RADS 4B Irregular, conspicuous calcifications that are generally between 0,5 mm and 1 mm and tend to coalesce but are smaller than dystrophic calcifications. Findings No previous exams available. When additional imaging studies are completed, a final assessment is made.

Enlarge the table by clicking on the image. Don’t forget to mention in the report that the lymph node on US corresponds with the noncalcified mass on mammography. Communicate unexpected findings with the referring clinician. These findings may have associated features, like for instance a mass can be accompanied with skin thickening, nipple retraction, calcifications etc.


There is one exception of the rule: Integrate mammography and US-findings in a single report. This patient presented with a mass on the mammogram at screening, which was assigned as BI-RADS 0 needs additional imaging evaluation.

This finding is sufficiently suspicious to justify biopsy. Standard Reporting Describe the indication for the study. In this year old patient the differential diagnosis consists of an atypical fibroadenoma or a phyllodes.

Contrast was injected into the node and a repeated mammogram was performed. There are 2 main types of biopsy; surgical biopsy or open biopsy and needle biopsy. Within this last group the chances of malignancy are different depending on their morphology BI-RADS 4B or 4C and also depending on their distribution. Stuff, is junk we keep. That is, there is something abnormal on mammogram but it is not breast cancer or malignant in any way.

Architectural distortion The term architectural distortion is used, when the normal architecture is distorted with no definite mass visible.

Cclasificacion arrangement of calcifications, the distribution, is at least as important as morphology. Addendum The biopsy showed a fibro-epithelial lesion, probably a benign phyllodes.

Here a hyperdense mass with an irregular shape and a spiculated margin. Verbal discussions between radiologist, patient and referring clinician should be documented in the original report or in an addendum.

Do realize, that a benign evaluation may always be rendered before completion of the Category 3 analysis, if in the opinion of the radiologist the finding has no chance of malignancy and thus is Category coasificacion.

Category 0 means clasifiaccion there is not enough information yet to complete the process. BI-RADS classifications have also helped in monitoring breast cancer treatment and supporting breast cancer research again by making statistics easier to calculate.

They all have characteristically benign appearances, and may be labeled with confidence. The margin of a lesion can be: Continue with the mammographic images after contrast injection.


The current rationale for using category 5 is that if the percutaneous tissue diagnosis is nonmalignant, this automatically should be considered as discordant. Compare to previous studies. As of the Atlas is divided into 3 publications:. Here we have proof that the mass is caused by an intramammary lymph node, since the mammographic mass mamorgafia the contrast. To find out whether the mamogtafia was within the area of the calcifications, contrast was injected into the mass.

Use in findings manografia which any nonmalignant percutaneous tissue diagnosis is automatically considered discordant Use in findings sufficiently suspicious to justify Category 5 and the patient or referring clinician refrain from makografia because of contraindications or other concerns.

The palpable mass is concordant with a solid mass, predominantly well circumscribed. Describe any significant finding using standardized terminology. DON’T Don’t use if only one highly suspicious finding is present. Here a non-palpable sharply defined mass with a group of punctate calcifications. Iffy, by which I mean, the words in the report are important, but the birads is an afterthought, and sometimes a clerk or assistant or a technologist just reads the radiologist report and assigns a bi-rads number onto the statistical recording data-entry field.

Mammography Overall breast composition: An asymmetry demonstrates concave outward borders and usually is interspersed with fat, whereas a mass demonstrates convex outward borders and appears denser in the center than at the periphery. The document focuses on patient reports used by medical professionals, not “lay reports” that are provided to patients.
