What is Breast MRI?
Magnetic Resonance Imaging (MRI) is one of the latest advancements in breast imaging today. Radio waves, a magnetic field, and a computer work together to create detailed images of the breast anatomy. MRI is not a replacement tool for mammography, but can be used to further evaluate the breasts. Breast MRI is useful for high risk patients, imaging dense breast tissue, and evaluating breast implant ruptures. In addition, Breast MRI is often used prior to breast surgery.

The MRI Exam
The technologist will position you on your stomach on the scanner table. Your breasts will be encircled in a cushioned opening allowing them to be visualized by the equipment. Compression is not used in Breast MRI. The scanner will make a rapid knocking noise as it acquires images of your breasts. You may receive a contrast injection through an IV in your arm. A routine exam will last about 45 minutes, but additional time may be needed if the radiologist requests more information.
Getting your results
In most cases, your imaging exam will be interpreted within 24 hours. Please keep in mind that your doctor’s office may need additional time to incorporate the report into your personal medical record.
