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.

Appropriate Action Should Be Taken: Ultrasound demonstrated a 37 mm mass with indistinct and angular margins and shadowing. Notice the distortion of the normal breast architecture on oblique view yellow circle and magnification view.

This includes thin straight lines or spiculations radiating from a point, and focal retraction, distortion or straightening at mampgrafia edges of the parenchyma. Don’t use for imaging findings, demonstrating suspicious findings other than the known cancer, then use Category 4 or 5. Yes, I would want a biopsy.

There may be variability within breast imaging practices, members of a group practice should agree upon a consistent policy for documenting. A benign lesion, although unlikely, is a possibility. Contrast was injected into the node and a repeated mammogram was performed. Solid lesions can be injected with contrast or a marker can be placed in difficult cases.

Fat-containing lesions such as oil cysts, lipomas, galactoceles and mixed-density hamartomas. 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. Screening, clasificaclon or follow-up.

Calcifications are now either typically benign or of suspicious morphology.

This proved to be DCIS with invasive carcinoma. In the version the approach has changed. Enlarge the table by clicking on the image. Both radiologists and patients prefer fast answers rather than having to wait for 6 months. The summary of each category, given below, is nearly identical for all 3 modalities.


Management The palpable cyst was painful, after informed consent uncomplicated puncture for suction of the clasifjcacion was performed. If the findings shows no change in the follow up the final assessment is changed to BI-RADS 2 benign and no further follow up is needed. Findings No previous exams available.

Cysts can be aspirated or filled with air after aspiration to make sure that the lesion found on the mammogram is caused by a cyst. At 12 month follow up more than five calcifications were noted in a group. Alone it has little specificity. The document focuses on patient reports used by medical professionals, not “lay reports” that are provided to patients.

This patient presented with a tumor in the left breast. In the atlas calcifications were classified by morphology and distribution either as benign, intermediate concern or high probability of malignancy.

Addendum The biopsy showed a fibro-epithelial lesion, probably a benign phyllodes. 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.

When you use more modalities, always make sure, that you are dealing with the same lesion. Another factor in breast density is whether the breasts are heterogeneously dense that is both the same. Use in the presence of suspicious unilateral lymphadenopathy without abnormalities in the breast Do use Category 4a in findings as: Both diagnoses are concordant mamovrafia the mammographic findings. Study the images and describe the calcifications.

Notice the focal skin retraction. Assuming stability perform a second short term follow-up after 6 months With mammography: Spiculated with radiating lines from the mass is a very suspicious finding.


This finding is sufficiently suspicious to justify biopsy. Always try to avoid this category by immediately doing additional imaging or retrieving old films before reporting. Associated features are things that are seen in association with suspicious findings like masses, asymmetries and calcifications.

In real-life terms, if a screening mammogram shows something like a round nodule and the radiologist thinks it might be a cyst not cancerthe radiologist will ask for an ultrasound and assign a BIRADS 0 category to the mammogram. Here images that you’ve seen before. The term density describes the degree of x-ray attenuation of clasifkcacion tissue but not discrete mammographic findings. Developing asymmetry new, larger and more conspicuous than on a previous examination.

Mammography Overall breast composition: For instance if there is a mass that causes architectural distortion, the likelihood of malignancy is greater than in the case of a mass without distortion.

Integrate mammography and US-findings in a single report. Category 2 is a definitive benign finding mamovrafia a routine birzds. Additional US of the mass: Special cases – cases with a unique diagnosis or pathognomonic ultrasound appearance:.

Here multiple round circumscribed low density masses in mamogratia right breast. Some areas in the breasts are sufficiently dense to obscure small masses.

Focal asymmetry visible on two projections, hence a real finding rather than superposition. To find out whether the mass was within the area of the calcifications, contrast was injected into the mass. These descriptors are arranged according to the risk of mamogfafia Like BI-RADS 1, this is a normal assessment, but here, the interpreter chooses to describe a benign finding in the mammography report, like:
