Risks

A breast MRI is a safe procedure that doesn't expose you to radiation. But as with other tests, a breast MRI has risks, such as:

  • A risk of false-positive results. A breast MRI may identify suspicious areas that, after further evaluation — such as a breast ultrasound or breast biopsy — turn out to be benign. These results are known as "false-positives." A false-positive result may cause unneeded anxiety if you undergo additional testing, such as a biopsy, to assess the suspicious areas.
  • A risk of reaction to the contrast dye used. A breast MRI involves injection of a dye to make the images easier to interpret. This dye can cause allergic reactions and can cause serious complications for people with kidney problems.
