Breast MRI

Early Detection with Advanced Breast MRI

At Exeter Hospital, breast magnetic resonance imaging (MRI) is an advanced test that uses a strong magnet and radio waves to create detailed pictures of the breast — without using radiation. The exam can detect breast abnormalities that may not be visible on other imaging tests.

During the exam, an intravenous (IV) line is placed so contrast dye (gadolinium) can be injected. This dye makes breast tissue and any abnormalities easier to see on the MRI. You'll lie comfortably face down on a padded table while your breasts are gently positioned for imaging — without compression. The exam usually takes less than an hour.

You will need a doctor’s order for this test. Because some insurance companies have special coverage rules for breast MRI, we recommend checking your benefits in advance.

What To Expect

Breast MRI can be difficult for women who experience claustrophobia. If you have concerns, talk with your doctor — medication may be available to help you stay comfortable during the exam.

MRI Works Best Alongside Mammograms

The American Cancer Society (ACS) recommends using breast MRI in addition to — not instead of — screening mammograms. While MRI is highly sensitive, some cancers may still only be detected by a mammogram — and vice versa.

Who Should Consider Breast MRI

The American Cancer Society recommends yearly breast MRI exams along with mammograms for women at higher risk of breast cancer, including women with any of the following risk factors:

• A BRCA1 or BRCA2 gene mutation
• A first-degree relative (parent, sibling, child) with a BRCA mutation who has not had genetic testing themselves
• A calculated lifetime breast cancer risk of 20–25% or greater, based on accepted risk-assessment tools that consider family history and other factors
• A history of radiation to the chest between the ages of 10 and 30
• Li-Fraumeni syndrome, Cowden syndrome, or Bannayan-Riley-Ruvalcaba syndrome — or a first-degree relative with one of these syndromes

If you believe you may be at high risk of developing breast cancer, talk with your doctor. You may also benefit from an evaluation in the High-Risk Breast Health Program, offered by Core Physicians in affiliation with Exeter Hospital.
