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.

This microcalcification is round but the edges are not sharply defined. It also facilitates outcome monitoring and quality assessment.

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 mamorgafia volume of fibroglandular tissue. Nevertheless the patient and the clinician preferred removal, because the radiologist was not able to clasficacion a clear differential diagnosis.

Focal asymmetry visible on two projections, hence a real finding rather than superposition. With ultrasound an intramammary lymph node was found, but we weren’t sure whether this was the same as the mass on the mammogram. 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 term architectural distortion is used, when the normal architecture is distorted with no definite mass visible. Don’t forget to mention in the report that the lymph node on US mmamografia with the noncalcified mass on mammography. When you use more modalities, always make sure, that you are dealing with the same lesion.

Clasigicacion use Category 2. Lesions appropriately placed in this category include:. Casting microcalcifications appear linear, fragmented, and branching. The term density describes the degree of x-ray attenuation of breast tissue but not discrete mammographic findings.

Mamograria with irregular shape. Lateral in the left clasiificacion, at 3 o’clock position in the posterior third of the breast, concordant with the palpable lump there is a 3 cm hyperdense mass with a rounded, but also irregular shape.


In the paragraph on location we will discuss how we can be sure that the lymph node that we found with ultrasound is indeed the same as the mammographic mass.

Both diagnoses are concordant with the mammographic findings. Associated features play a role in the final assessment. Clasificcaion add the following sentence in your report: In the atlas calcifications were classified by morphology and distribution either as benign, intermediate concern or high probability of malignancy. 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.

To find out whether the mass was within the area of the calcifications, contrast was injected into the mass. So, if you do come across these terms in your report it may be useful to know what they mean.

The Radiology Assistant : Bi-RADS for Mammography and Ultrasound

The document focuses on patient reports used by medical professionals, not “lay reports” that are provided to patients. This page was last edited on 15 Mayat Assuming stability perform a second short term follow-up after 6 months Mamogrxfia mammography: No previous exams available. Ultrasound of the region demonstrated an irregular mass, which proved to be an adenocarcinoma with fine needle aspiration FNA.

In other projects Wikimedia Commons. On the initial mammogram a marker is placed in the palpable tumor. The palpable mass is concordant with a solid mass, predominantly well circumscribed. Yes, I would want a biopsy.

The accuracy statistics are generally calculated once a year and they are important in quality assurance, that is they tell the radiologist whether they are doing a good job or not. The mass is equal dense compared to the fibroglandular tissue. Additional US of the mass: Continue with clasficacion mammographic images after contrast injection.

The system is a collaborative effort of many health groups but is published and trademarked by the American College of Radiology ACR. There are at least two more, smaller cysts present in the right breast. Addendum The biopsy showed a fibro-epithelial lesion, probably a benign phyllodes.


Asymmetries Findings that represent unilateral deposits of fibroglandulair tissue not conforming to the definition of clasifciacion mass. For example, extreme patient anxiety or plans for pregnancyplans for breast augmentation or birada surgery, or if synchronous carcinoma is present. Asymmetry as an area of fibroglandulair tissue visible on only one mammographic projection, mostly caused by superimposition of normal breast tissue.

Lesions appropriately placed in this category include: Irregular spiculated mass with associated pleomorphic calcifications.

In real-life terms, if a screening mammogram shows something like a round nodule and the radiologist mxmografia it might be a cyst not cancerthe radiologist will ask for an ultrasound and assign a BIRADS 0 category to the mammogram. Assuming stability perform a follow-up after one year and optionally after another year.

Ultrasound demonstrated a 37 mm mass with indistinct and angular margins and shadowing. This patient presented with a mass on the mammogram at screening, which was assigned as BI-RADS 0 needs additional imaging evaluation. Then use category 4. Designation of right or left breast Quadrant and clockface notation preferably both On US quarter and clockface notation should be supplemented on the image by means of bodymark and transducer position. This finding is sufficiently suspicious to justify biopsy.

Distribution of calcifications The arrangement of calcifications, the distribution, is at least as important as morphology. Many descriptors for ultrasound are the same as for mammography.

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

Special cases – cases with a unique diagnosis or pathognomonic ultrasound appearance:. Then use Category 4c.
