The VCU Department of Radiology has specialty-trained radiologists who use magnetic resonance imaging of the breast to detect abnormalities of the breast and breast cancer.
Magnetic resonance imaging of the breast (breast MRI) does not use ionizing radiation. Rather it uses a magnetic field to generate images of the breast before and after a contrast injection to detect cancer. The breast MRI is used as a supplemental procedure with mammography or ultrasound to evaluate abnormalities and screen high-risk patients for breast cancer.
Several risk assessment tools are used to estimate a woman’s breast cancer risk, including BRCAPRO, the Claus model and the Tyrer-Cuzick model. Based on different combinations of factors, these tools estimate breast cancer risk. Depending on the tool used, different risk estimates may be calculated for the same woman.
According to the American Cancer Society Guidelines, women at high risk should get a breast MRI and a mammogram beginning at age 30. Women at moderate risk should talk with their doctors about adding MRI to their yearly mammogram. Yearly breast MRI screening is not recommended for women whose lifetime risk of breast cancer is less than 15 percent.
The Breast Imaging Center at VCU Health is the first facility in Virginia to earn the American College of Radiology Breast Imaging Center of Excellence designation.

Breast MRI before intravenous contrast
Thin (1 mm) images of the breasts are done before intravenous contrast is given. The images are repeated at timed intervals after the contrast is injected. Because of abnormal blood vessels, cancers take and give up the contrast quickly after the injection. In comparison, normal tissue and benign tumors take up the contrast in a slower manner and may not release the contrast until after 10 minutes following the injection.
Breast MRI image after intravenous contrast
Breast MRI done within the first two minutes after the contrast injection shows a mass (arrow) taking up the contrast abnormally. The surrounding normal tissue does not show initial enhancement. In addition to the information regarding the shape and borders of a mass, with breast MRI provides information about the blood vessels in the tumor.
