Magnetic Resonance Imaging (MRI) of the Breast

Magnetic Resonance Imaging (MRI) of the Breast

Why It Is Done

An MRI of the breast is done to:

  • Find breast cancer. Breast MRI may be done when a mammogram or breast ultrasound scan cannot tell if a lump is cancer.
  • Check women who are at increased risk for breast cancer. This includes women with:
    • Gene changes (such as BRCA).
    • Close family members who have had breast cancer.
    • A history of radiation therapy to the chest as a child.
  • Choose the best treatment for breast cancer. It may also be used to check breast tissue changes during treatment.
  • Check breasts with nipple changes for signs of breast cancer. These changes include inverted nipples, nipples with scaly skin that flakes off, and nipples with abnormal discharge.
  • Check women with breast implants. MRI may be used to look for breast cancer or to check if the implant is leaking.

Women at increased risk for breast cancer may have screening tests that alternate between MRIs and mammograms. This is done because the tests can detect different kinds of problems.
