Breast MRI

MRI of the breast offers valuable information about many breast conditions that cannot be obtained by other imaging modalities, such as mammography or ultrasound. MR imaging uses a powerful magnetic field, radio waves and a computer to produce detailed pictures of organs, soft tissues, bone and virtually all other internal body structures. The images can then be examined on a computer monitor or printed. MRI does not use ionizing radiation (x-rays). MRI of the breast is not a replacement for mammography or ultrasound imaging but rather a supplemental tool for detecting and staging breast cancer and other breast abnormalities.

Breast MRI is performed to:

  • Evaluate abnormalities detected by mammography.
  • Identify early breast cancer not detected through other means, especially in women with dense breast tissue and those at high risk for the disease.
  • Screen for cancer in women who have implants or scar tissue that might jeopardize an accurate result from a mammogram.
  • Determine the integrity of breast implants.
  • Distinguish between scar tissue and recurrent tumors.
  • Assess multiple tumor locations.
  • Look for multiple tumors prior to breast conservation surgery.
  • Determine whether cancer detected by mammography or ultrasound has spread further in the breast or into the chest wall.
  • Determine how much cancer has spread beyond the surgical site after a breast biopsy or lumpectomy.
  • Assess the effect of chemotherapy.
  • Provide additional information on a diseased breast to make treatment decisions.
