Digital mammography

At St. Peter’s Health, we have 3D mammograms (also known as tomosynthesis) and 3D stereotactic breast biopsy. 

We also offer a low-dose X-ray exam of the breast that aids in the early detection of breast cancer. It provides incredibly sharp, clear images that are instantly seen by the technologist to ensure a high quality picture. Careful study is made of each image including the use of Computer Aided Detection.

What to expect during a mammogram

When you arrive for your screening mammogram you can expect a fairly quick procedure.  You will be shown to a private dressing room and given time to undress from the waist up and put on your cape. 

Each woman is provided with a comfortable robe for her privacy and comfort.  We will then proceed to the exam room where a series of images are taken.  You can expect your technologist to guide you through the process and explain why compression is necessary. Your technologist will also work with you to find a comfortable pace and ensure that you are working together at all times.  This procedure normally takes less than 20 minutes.

Preparing for the exam

  • Wear a two piece outfit to easily remove clothing from the waist up.
  • Do not wear lotion, powder or deodorant.  These may cause artifacts on the images.
  • Try to schedule an appointment at the end of your menstrual cycle when your breasts are less sensitive.
  • If you have sensitive breasts consider taking an over-the-counter pain reliever an hour before your exam, but avoid aspirin products.
  • If you have had a previous mammogram at another facility please ask them to send us your most recent images. Your new radiologist will need these images for comparison.
