Radiology of the Normal Breast and Overview of Breast Imaging Reporting and Data System
Until breast cancer can be prevented, regular screening programs are widely recommended for asymptomatic women. The goal of breast cancer screening is early detection of disease, to be followed by appropriate treatment. Evaluating any screening program is challenging, and breast cancer screening has been subject to many controversies over the years. The many modalities that have been studied for possible inclusion in screening programs include screening mammography, ultrasound, and magnetic resonance imaging. Awareness of the breast anatomy is essential in order to generate an accurate differential diagnosis and guide patient management. Use of standardized terminology, report organization, and assessment structures allows radiologists to communicate breast imaging findings to referring physicians clearly and succinctly. The Breast Imaging Reporting and Data System (BI-RADS) lexicon was released by the American College of Radiology (ACR) with the goal of standardizing mammography reporting by providing a specific lexicon of imaging features. The purpose of this chapter is to review current knowledge of breast anatomy with a focus on relevant anatomy for diagnosis and intervention, and to provide a general overview of the BI-RADS lexicon.
