Breast MRI

A breast MRI is a non-invasive study used to further assess a suspicious area on a mammogram. Unlike mammography, breast MRI does not compress the breast. It is important to note that breast MRI is not a replacement for traditional mammography and breast self-exams but is extremely useful for women who:

• Have a known breast cancer
• Are at high risk for developing breast cancer
• Have implants and may have experienced a rupture
• May have particularly dense breast tissue

Each breast MRI exam produces hundreds of images of the breast, which can be thought of as thin slices of detailed information. These cross-sectional slices can be viewed side-to-side, top-to-bottom, or front-to-back.

What to expect

Before a breast MRI, you may receive a contrast agent through an IV in your arm. This contrast agent will help to highlight the tissues so abnormalities can be seen more clearly.

During a breast MRI, you’ll lie on your stomach with both breasts resting in a cushioned recess known as the breast coil. If IV contrast is being used, it will be administered at this time. Generally, IV contrast is very safe but be sure to tell the technologist is you have ever had a reaction to MRI contrast or if you are particularly sensitive to medications.

Once the IV is started, the entire table will be advanced into the opening of the MRI machine. You’ll be asked to lie still for up to 15 minutes at a time while the computer acquires the images. The total examination is made up of several scans, usually 5 to 15 minutes in length, and you can expect to be in the exam room for a total of about 45 minutes.

How to prepare

There is no special preparation for a breast MRI. However, because MRI imaging uses a very strong magnet, you will be asked to remove eyeglasses, watches, jewelry, dentures, hearing aids, or other metallic objects. In addition, be sure to inform the radiologist if you are pregnant.

Getting your results

After your study is over, the images will be evaluated by one of our board certified radiologists, with expertise in MRI breast imaging. A final report will be sent to your physician who can then discuss the results with you in detail.
