3D Digital Mammography is a revolutionary new screening and diagnostic tool designed for early breast cancer detection. It is known to detect 41% more invasive breast cancers and can reduce false positives by up to 40%.

Also known as Breast Tomosynthesis and Digital Breast Tomosynthesis, 3D Digital Mammography is an advanced form of breast imaging where multiple images of the breast from different angles are captured and “synthesized” into a 3D image set.

CORA and CMI are the only certified ACR “Breast Imaging Center of Excellence” facilities offering 3D technology in Central and Eastern Oregon.

A 3D Digital Mammogram allows our radiologists to examine your breast tissue layer by layer.

3D Digital Mammography is clinically proven to be superior to the traditional 2D mammography in extensive research published by the Journal of American Medical Association (JAMA). Where traditional 2D mammogram views of your breast tissue are in a flat image, 3D mammography allows fine details to be visible once hidden by the tissue above or below.





Exam Pointers

  • Before scheduling a 3D digital mammogram, the American Cancer Society (ACS) and other specialty organizations recommend that you discuss any new findings or problems in your breasts with your doctor. In addition, inform your doctor of any prior surgeries, hormone use, and family or personal history of breast cancer.
  • Do not schedule your mammogram for the week before your menstrual period if your breasts are usually tender during this time. The best time for a mammogram is one week following your period.
  • Always inform your doctor or x-ray technologist if there is any possibility that you are pregnant.
  • The ACS also recommends you do not wear deodorant, talcum powder or lotion under your arms or on your breasts on the day of the exam. These can appear on the mammogram as calcium spots.
  • Obtain your prior mammograms and make them available to the radiologist if they were done at a different location. This is needed for comparison with your current exam and can often be obtained on a CD.
