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.

Notice the distortion of the normal breast architecture on oblique view yellow circle and magnification view.

A resection was performed and only scar tissue was found in the specimen. Birxds proved to be DCIS with invasive carcinoma. Journal of Digital Imaging. These descriptors are arranged according to the risk of malignancy:.

There are at least two more, smaller cysts present in the right breast. Special cases – cases with a unique diagnosis or pathognomonic ultrasound appearance:. The ultrasound lexicon has many similarities to the mammography lexicon, but there are some descriptors that are specific for ultrasound.

There was a problem providing the content you requested

Views Read Edit View history. It contains a lexicon for standardized terminology descriptors for mammography, breast US and MRI, as well as chapters on Report Organization and Guidance Chapters for use in daily practice.

The fastest and most economical way to arrive at a positive or confirmed diagnosis of breast cancer is by core needle biopsy. Now a clqsificacion assisted biopsy has to be performed of the calcifications, clasifidacion maybe we are dealing with DCIS in one area and an invasive carcinoma in another area. Communicate unexpected findings with the referring clinician.

Here images that you’ve seen before. So, your medical advisor will request an immediate biopsy.

This will re-assure the good radiologists to keep doing whatever they are doing, but for radiologists whose accuracy statistics are not very good, it lets them know that they ought to get more training. Yes, I would want a biopsy.

Category 0 means that there is not enough information yet to complete the process. Historically this would have been called an ACR 2: Most biopsies today are done with a needle under local anesthetic and are painless. The summary of each category, given below, is nearly identical for all 3 modalities. In the BI-RADS edition the assignment of the breast composition is changed into a, b, c and d-categories followed by a description: 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.

Notice the focal skin retraction. Integrate mammography and US-findings in a single report. Assuming stability perform a second short term follow-up after 6 months With mammography: BI-RADS classifications have also helped in monitoring breast cancer treatment and supporting breast cancer research again by making statistics easier to calculate.

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.


The system is a collaborative effort of many health groups but is published and trademarked by the American College of Radiology ACR. Irregular spiculated mass with associated pleomorphic calcifications. Nonpalpable, circumscribed mass on a baseline mammogram unless it can be shown to be a cyst, an intramammary lymph node, or another benign findingFocal asymmetry which becomes less dense on spot compression view Solitary group of punctate calcifications.

BI-RADS mammogram classifications are generalizations and tend to revolve around the presence and type of microcalcifications. If a potential mass is seen in only a single projection it should be called a ‘asymmetry’ until its three-dimensionality is confirmed.

Appropriate Action Should Be Taken: Asymmetries Findings that represent unilateral deposits of fibroglandulair tissue not conforming to the definition of a mass. These are standardized numerical codes typically assigned by a radiologist after interpreting a mammogram. Mass A ‘Mass’ is a space occupying 3D lesion seen in two different projections.

These descriptors are arranged according to the risk of malignancy: On US poorly characterized compared with mammography, but can be recognized as echogenic foci, particularly when in a mass. Indication for examination Referral from general practitioner. As of the Atlas is divided into 3 publications:. Retrieved from ” https: Automatic parsers have been developed to automatically extract BI-RADS features, [6] [7] categories [8] and breast composition [9] from textual mammography reports.

Screening, diagnostic or follow-up. This is a benign finding.
