E1861. All Lit Up: A Comprehensive Update on Contrast-Enhanced Mammography
In the armamentarium of modalities available in the screening and diagnosis of breast cancer, contrast-enhanced mammography (CEM) is an emerging imaging tool that can add value to our care of women. Although 2D mammography has been around since the 1970’s, CEM, which was developed in the early 2000s, has emerged at some institutions across the country over the past decade as an alternative to MRI. In some circumstances, CEM can be nearly equivalent to MRI. Although some cancer centers have adopted CEM, many breast imagers are still not comfortable with its interpretation, familiar with its indications, or understand its limitations. The purpose of this educational exhibit is to educate radiologists on CEM.
Educational Goals / Teaching Points
This presentation will review CEM, including how it is performed, its indications, recent research studies, the physics involved, as well as potential benefits when compared with MRI such as cost and limitations of MRI. The target audience is breast radiologists, general radiologists, residents, and medical physicists.
Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
CEM is an emerging technology that has been shown to be nearly equivalent to MRI in some circumstances. Its use, however, has yet to become mainstream. CEM is still in its developing stages because of technical considerations. With continued breast radiologist education, it is possible for algorithms to include CEM as an alternative to MRI and it will likely play a larger role in breast imaging in the future.
