Breast MRI

Breast MRI is not a replacement for mammography or ultrasound imaging, but rather is a supplemental tool for detecting and staging breast cancer and other breast abnormalities. MRI is used 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.
  • determine the integrity of breast implants.
  • distinguish between scar tissue and recurrent tumors.
  • assess multiple tumor locations.
  • check the progress of chemotherapy.
  • 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.
  • provide additional information on a diseased breast to make treatment decisions.
Because the risks to a fetus are unknown, pregnant women should not have an MRI exam unless the potential benefit from the MRI is determined to outweigh the potential risks.
