1. To review the imaging lexicon and highlights from the 2013 5th Edition of the ACR BI-RADS Atlas. 2. To emphasize the complementary imaging information each modality provides using a pictorial review. a. Mammography (MG): Evaluation of calcifications, breast symmetry, convenient study for overview of the breasts. b. Breast Ultrasound (US): Detailed evaluation of morphology, assessment of cystic/solid components, detection of vascularity, and real-time analysis. c. Breast MRI (MR): Visualization of angiogenesis, large field of view, accuracy in dense breasts, and detection of multifocal/multicentric disease. 3. To review potential pitfalls using a pictorial review: a. MG: Limited FOV, limited sensitivity in dense breasts, underestimation of extent. b. US: Poor evaluation of deep structures, limited ability to evaluate calcifications, operator dependence. c. MRI: Decreased sensitivity with background parenchymal enhancement, false positives, contraindications to MR, inaccuracies with lesion extent, and increased interpretation time.

1. The imaging lexicon and highlights from the 2013 5th Edition of the ACR BI-RADS Atlas are central to the proficient practice of breast imaging. 2. Each modality provides unique and complementary information and has potential pitfalls.
