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.

Sistema de informes y registro de datos de estudios por imágenes de la mama

Then use Category 4. Location and size should be applied in any lesion, that must undergo biopsy. The breasts are symmetric and no masses, architectural distortion or suspicious calcifications are present.

BI-RADS 2 DO Agree in a group practice on whether and when to describe benign findings in a report Use in screening or in diagnostic imaging when a benign finding is present Use in the presence of bilateral lymphadenopathy, probably reactive or infectious in origin Use in diagnostic imaging and recommend management if appropriate, – as in abscess or hematoma mamografla as in implant rupture and other foreign bodies DON’T Don’t use when a benign finding is present but not described in the report, then use Category 1.

Mass A ‘Mass’ is a space occupying 3D lesion seen in two different projections. Calcifications are now either typically benign or of suspicious morphology. The pathologist could report to you that it is sclerosing adenosis or ductal carcinoma in situ. Fat-containing lesions such as oil cysts, lipomas, galactoceles and mixed-density hamartomas.

Right breast, 9 o’clock position, middle third of the breast. The patient and the referring general practitioner preferred to await the results of the biopsy.


clasificaciin Then use category 4. Examples of reporting Indication for examination Painful mobile lump, lateral in right breast. This includes thin straight lines or spiculations radiating from a point, and focal retraction, distortion or straightening at the edges of the parenchyma. It was discussed with the patient and the referring general practitioner, that in case of BI-RADS 4 a referral to the breast clinic is advised.

Clasifjcacion areas of fibroglandular density. Here an example of global asymmetry. That is, there is something abnormal on mammogram but it is not breast cancer or malignant in any way.

The current rationale for using category 5 is that if the percutaneous tissue diagnosis is nonmalignant, this automatically should be considered as discordant.

The Radiology Assistant : Bi-RADS for Mammography and Ultrasound

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. This has to be differentiated from a mass. This is also a suspicious finding.

Use BI-RADS 1 if there are no abnormal imaging findings in a patient with a palpable abnormality, possible a palpable cancer, BUT add a sentence recommending surgical consultation or tissue diagnosis if clinically indicated. Findings that represent unilateral deposits of fibroglandulair tissue not conforming to the definition of a mass.

Use in findings on mammography like – Noncalcified circumscribed solid mass – Focal asymmetry – Solitary group of punctuate calcifications Use in findings on US with robust evidence to suggest – Typical fibroadenoma – Isolated complicated cyst – Clustered microcysts Use in a probably benign finding, while the patient or referring clinician still prefers biopsy.

Category 6 indicates a known cancer, proven by biopsy. Automatic parsers have been developed to automatically extract BI-RADS features, [6] [7] categories [8] and breast composition [9] from textual mammography reports. If the findings shows no change in the follow up the final clasificacio is changed to BI-RADS 2 benign and no further follow up is needed.


Like BI-RADS 1, this is a normal assessment, but here, the interpreter chooses to describe a benign finding in the mamigrafia report, like: They are of a patient with a new lesion found at screening. Since calcifications of intermediate concern and of high probability of malignancy all are being treated the same way, which usually means biopsy, clasificacio is logic to group them together.

Developing asymmetry new, larger and more conspicuous than on a previous examination.

BI-RADS – Wikipedia

Asymmetry as an area of fibroglandulair tissue visible on only one mammographic projection, mostly caused by superimposition of normal breast tissue. Verbal discussions between radiologist and referring clinician should be documented in the report.

All types of asymmmetry have different border contours than true masses and also lack the conspicuity of masses. Posterior features represent the attenuation characteristics of a mass with respect to its acoustic transmission, also of additional value. First study the images and describe the findings. Instead of stopping the follow-up, tissue diagnosis will be performed, due to patient and referring clinician concern.

Don’t recommend MRI to further evaluate a probably benign finding. Then use Category 4c. Nevertheless the patient and the clinician preferred removal, because the radiologist was not able to present a clear differential diagnosis.
