Breast Magnetic Resonance Imaging (MRI)

Who might need a breast MRI?

You’ll need a referral from your clinician for a breast MRI, which is useful for:

• Screening women with a strong family history of breast cancer and therefore are at high risk
• Evaluating patients who screen positive for BRCA gene mutations
• Determining extent of cancer for patients with a recent diagnosis
• Evaluating areas of concern detected on mammography
• Evaluating patients undergoing chemotherapy before breast cancer surgery
• Evaluating the integrity of silicone implants

What is needed to prepare for the test?

MRI studies do not use ionizing radiation and are safe for most patients; however, some patients may require precautions because of the strong magnetic field. Inform staff if you have metal in your body, such as a pacemaker, aneurysm clips, a cochlear implant, shrapnel or breast tissue expanders.

Do not wear jewelry, other objects containing metal or deodorant. We provide a secure locker for personal articles.

What can I expect during my breast MRI?

The MRI requires an injection of contrast material administered by an IV line started in your hand or arm. MRI contrast is a gadolinium-based liquid that enhances MRI images and provides additional information for diagnosis.

For your study, you’ll be lying face down on a special table, with your breasts suspended and slightly compressed. The technologist will be able to see, hear and speak with you during the hourlong exam. We will provide hearing protection since the MRI can emit loud sounds. If you are concerned about anxiety or claustrophobia, ask your clinician about prescribing a mild sedative. If taking a sedative, you will need someone to drive you home after the study.

How soon can I expect the results?

Your MRI will be interpreted by a radiologist who specializes in breast imaging. A report with a detailed explanation of the findings will be sent to your clinician. Sometimes a follow-up examination including ultrasound may be recommended. This will be conveyed to your referring physician in the report.

Will my insurance cover a breast MRI?

The Food and Drug Administration (FDA) approves breast MRIs, and the American College of Radiology has specific indications for its use. Many insurances cover breast MRIs for the following purposes:

• Follow-up after suspicious mammogram or ultrasound
• After lumpectomy
• Evaluating both breasts when cancer is recently diagnosed
• Evaluating response after chemotherapy and before breast surgery
• When recommended by genetic counseling for women at very high risk for developing breast cancer
• When cancer is suspected in women with breast implants or after breast reconstruction
