BIRADS_ The BI-RADS® atlas provides standardized breast imaging terminology, report organization, assessment. The much-anticipated fifth edition of the American College of Radiology (ACR) Breast. Imaging Reporting and Data System (BI-RADS) lexicon was released.
It is an updated version of the article. We encourage anyone who is involved in breast imaging to order the illustrated atlas to get a full knowledge of BI-RADS edition It also facilitates outcome monitoring and quality assessment. 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. Standard Reporting Describe the indication for the study. Screening, diagnostic or follow-up. Mention the patient's history.
Communicate unexpected findings with the referring clinician. Verbal discussions between radiologist, patient or referring clinician should be documented in the report. Mammography and Ultrasound Lexicon The table shows a summary of the mammography and ultrasound lexicon. Enlarge the table by clicking on the image. First describe the breast composition. When there is a significant finding use the descriptors in the table.
The ultrasound lexicon has many similarities to the mammography lexicon, but there are some descriptors that are specific for ultrasound. We will discuss the lexicon in more detail in a moment. We will first discuss the breast imaging lexicon of mammography and ultrasound and then discuss in more detail the final assessment categories and the do's and don'ts in these categories.
In BI-RADS the use of percentages is discouraged, because in individual cases it is more important to take into account the chance that a mass can be obscured by fibroglandular tissue than the percentage of breast density as an indicator for breast cancer risk.
In the BI-RADS edition the assignment of the breast composition is changed into a, b, c and d-categories followed by a description: a- The breast are almost entirely fatty.
Mammography is highly sensitive in this setting. The term density describes the degree of x-ray attenuation of breast tissue but not discrete mammographic findings. Some areas in the breasts are sufficiently dense to obscure small masses. The fibroglandular tissue in the upper part is sufficiently dense to obscure small masses.
So it is called c, because small masses can be obscured. Mass A 'Mass' is a space occupying 3D lesion seen in two different projections.
If a potential mass is seen in only a single projection it should be called a 'asymmetry' until its three-dimensionality is confirmed. Shape: oval may include 2 or 3 lobulations , round or irregular Margins: circumscribed, obscured, microlobulated, indistinct, spiculated Density: high, equal, low or fat-containing. The images show a fat-containing lesion with a popcorn-like calcification. All fat-containing lesions are typically benign.
These image-findings are diagnostic for a hamartoma - also known as fibroadenolipoma. The shape of a mass is either round, oval or irregular. Always make sure that a mass that is found on physical examination is the same as the mass that is found with mammography or ultrasound.
Location and size should be applied in any lesion, that must undergo biopsy. The margin of a lesion can be: Circumscribed historically well-defined. This is a benign finding. Obscured or partially obscured, when the margin is hidden by superimposed fibroglandular tissue. Ultrasound can be helpful to define the margin better. This implies a suspicious finding. Indistinct historically ill-defined.
This is also a suspicious finding. Spiculated with radiating lines from the mass is a very suspicious finding.
The density of a mass is related to the expected attenuation of an equal volume of fibroglandular tissue. High density is associated with malignancy. It is extremely rare for breast cancer to be low density. Here multiple round circumscribed low density masses in the right breast. These were the result of lipofilling, which is transplantation of body fat to the breast. Here a hyperdense mass with an irregular shape and a spiculated margin.
Notice the focal skin retraction. Architectural distortion The term architectural distortion is used, when the normal architecture is distorted with no definite mass visible. This includes thin straight lines or spiculations radiating from a point, and focal retraction, distortion or straightening at the edges of the parenchyma.
