Background
Early detection of breast cancer through screening mammography can decrease mortality . The mammographic appearance of breast cancer varies and can present with calcifications. Both invasive and in-situ breast cancer can form calcium deposits within the terminal ductal lobule (TDLU), highlighting the importance of early detection of new calcifications. The Breast Imaging Reporting and Data System (BI-RADS) lexicon is used to describe and report calcifications based on their location, morphology, and distribution. The use of the lexicon helps stratify the risk of the calcifications based on suspicious features and helps guide management. The purpose of this educational exhibit is to review the imaging features and reporting of breast calcifications.

Educational Goals / Teaching Points
After participating in this educational exhibit the learner will be familiar with the BI-RADS lexicon terms used to characterize calcifications. The learner will also become familiar with the reporting style used in breast imaging and will be able to correctly identify the location, distribution, and morphology of calcifications. The learner will know which additional images (spot compression magnification views in the craniocaudal and the true lateral projections) are needed for full characterization of calcifications. This educational exhibit is a case-based educational exhibit with a test your knowledge theme to help solidify or review breast calcifications. By the end of the educational exhibit, the learner will be able to accurately report and identify both typically benign and suspicious features and will know what the next step in management should be.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
This exhibit will review breast anatomy including the terminal ductal lobule, lobular and intraductal calcifications, BI-RADS lexicon (2013), and additional imaging to characterize calcifications. The case review will focus on location (laterality, quadrant and clock face, depth), distribution (diffuse, regional, grouped, linear, segmental), and morphology (typically benign vs suspicious features). Finally, this exhibit will cover the radiology report and what is the next step in management.

Conclusion
Identifying new or changing breast calcifications in mammography plays a key role in early diagnosis and decreased mortality in breast cancer. It is important for radiologists in all stages of their training to be familiar with the BI-RADS lexicon for breast calcifications and be able to identify and characterize calcifications. After partaking in this educational exhibit, the learner will be able to diagnose, work up, and guide further management of breast calcifications.
