Beyond the standard: How contrast-enhanced mammography advances breast cancer detection

For decades, traditional mammograms were the gold standard for breast cancer detection. Later, they were enhanced by the detailed views of 3D tomosynthesis. Today, a new level of clarity has arrived with contrast-enhanced mammography (CEM), now available at MSU Health Care at McLaren Greater Lansing Breast Imaging Center. This imaging technology is a significant advancement specifically designed to provide clearer imagery for women with dense breast tissue or who have a higher risk of breast cancer.

How does CEM work?

By combining the familiar process of mammography, CEM offers a functional look at breast health that goes beyond what the naked eye can see on a standard scan, with the addition of iodine-based contrast dye.

“When we perform the mammogram, there is a low-energy and a high-energy image that is created, and with this method, we are not only left with the mammogram image, but we are given a look at anything that is enhancing in the breast, making this an exceptionally effective tool for identifying breast cancer,” said Dr. David Rawson, lead interpreting physician at the MSU Health Care at McLaren Greater Lansing Breast Imaging Center.

Benefits of CEM

“One of the biggest challenges we have when detecting breast cancer is breast density. Breast density shows white on mammography, and so does cancer. Dense breast tissue can mask cancers. The contrast enhancement isn’t affected by density and helps detect cancers much better,” said Dr. Rawson. 

Even in the densest tissue, a tumor will stand out because of the contrast agent, significantly reducing the risk of a missed diagnosis.

Faster, more comfortable MRI alternative

 While an MRI is a powerful tool, it may not be for everyone. Some patients struggle with claustrophobia in the MRI machine, while others have metal implants or other devices that prevent them from being able to undergo the testing. CEM cancer detection rates are very similar to those rates from a breast MRI, but a CEM can be performed faster and at a lower cost.

“A CEM exam takes about 10 minutes only, compared to a breast MRI that can take over 30 minutes, making it a lot more comfortable for patients to undergo,” said Dr. Rawson.

Additionally, rather than requiring patients lie face down, and an MRI does, a CEM is done just as a standard mammogram is, allowing them to remain upright.

Annual mammograms are recommended for women beginning at age 40. However, if you have a higher risk of breast cancer, talk to your doctor about starting earlier.
