Background
Though mammography and ultrasound remain first-line breast imaging modalities, the role of contrast-enhanced breast MRI is steadily expanding. One area in which breast MRI has been shown to be a powerful tool is for treatment planning in patients diagnosed with breast cancer. The superior tissue definition and detail provided by MRI allows for assessment of key anatomic structures that affect major treatment decisions, such as whether to pursue initial definitive surgical management or neoadjuvant chemotherapy.

Educational Goals / Teaching Points
The purpose of this educational exhibit is to review anatomic structures and findings on contrast-enhanced breast MRI that are essential for radiologists to recognize because of the impact they have on breast cancer treatment planning.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
Through a series of illustrative and engaging cases, this educational exhibit will review key imaging findings on contrast-enhanced breast MRI that alter treatment and management decisions. These cases will explore regional anatomic structures, such as the chest wall, nipple-areolar complex, pectoralis muscle, and regional lymph nodes. Additionally, the cases will highlight certain extramammary structures that are included in the field-of-view of breast MRI, such as lungs, pleura, liver, and bone, which can reveal distant metastases that alter management decisions.

Conclusion
As the role of breast MRI continues to expand, it is essential for radiologists to be familiar with the key anatomic structures and imaging findings that affect breast cancer treatment planning.
