Optimal integration of imaging has important implications for all phases of breast cancer management from diagnosis and treatment though follow-up care. This session will focus on three imaging modalities, specifically breast tomosynthesis, MRI and CT, and their respective emerging roles in breast cancer management. The role of breast tomosynthesis in screening and diagnosis of breast cancer will be elucidated. The indications and value of breast MRI once a breast cancer diagnosis is established for determining the extent of disease, response to treatment, and surveillance will be examined. Defining CT-based target and normal tissue volumes is integral to radiation delivery. How these vary based on the clinical scenario and treatment method will be reviewed.
