Architectural distortion found on a mammogram. Architectural distortion is a somewhat vague phrase used by radiologists, when the mammogram shows a region where the breasts normal appearance, looks like an abnormal arrangement of tissue strands, often a radial or perhaps a somewhat random pattern, but without any associated mass as the apparent cause of this distortion.
Architectural distortion is the third most common mammographic appearance of non-palpable breast cancer, representing nearly 6% of abnormalities detected on screening mammography. Although its prevalence on mammography is small compared with calcification or visible mass, architectural distortion is also more difficult to diagnose because it ...
When Patient X came in for her annual mammogram and first in 3D, the radiologist noted some architectural distortion, However, knowing the woman's history of previous benign excisional biopsies and seeing that it looks stable compared to previous years she attributed it to a prior surgery and makes her report.
Architectural Distortion No mass was seen, but the appearance of the breast tissue is not normal. The radiologist’s level of concern will depend on what is contributing to the distortion.
Introduction. Architectural distortion (AD) is defined as distorted parenchyma with no definite mass ().According to the Breast Imaging Reporting and Data System (BI-RADS) lexicon, “For mammography, this includes thin straight lines or spiculations radiating from a point, and focal retraction, distortion, or straightening at the anterior or posterior edge of the parenchyma” ().
Computer-aided detection (CADe), also called computer-aided diagnosis (CADx), are systems that assist doctors in the interpretation of medical images. Imaging techniques in X-ray, MRI, and ultrasound diagnostics yield a great deal of information that the radiologist or other medical professional has to analyze and evaluate comprehensively in a short time. CAD systems process digital images for typical appearances and to highlight conspicuous sections, such as possible diseases, in order to offer input to support a decision taken by the professional. CAD also has potential future applications in digital pathology with the advent of whole-slide imaging and machine learning algorithms. So far its application has been limited to quantifying immunostaining but is also being investigated for the standard H&E stain. CAD is an interdisciplinary technology combining elements of artificial intelligence and computer vision with radiological and pathology image processing. A typical application is the detection of a tumor.
Breast cancer screening is the medical screening of asymptomatic, apparently healthy women for breast cancer in an attempt to achieve an earlier diagnosis. The assumption is that early detection will improve outcomes. A number of screening tests have been employed, including clinical and self breast exams, mammography, genetic screening, ultrasound, and magnetic resonance imaging. A clinical or self breast exam involves feeling the breast for lumps or other abnormalities. Medical evidence, however, does not support its use in women with a typical risk for breast cancer. The use of mammography in universal screening for breast cancer is controversial as it may not reduce all-cause mortality and for causing harms through unnecessary treatments and medical procedures. Many national organizations recommend it for most older women. In the United States screening mammography women at normal risk for breast cancer, is only recommended every two years in women between the ages of 50 and 74. Several tools are available to help target breast cancer screening to older women with longer life expectancies.
In oncology, a spiculated mass is a lump of tissue with spikes or points on the surface. It is suggestive but not diagnostic of malignancy, i.e. cancer. It's a common mammography finding in carcinoma breast.
