Thanks to a grant award from the New York State Department of Health, Bertrand Chaffee Hospital has added 3D Mammography to its imaging department as of September 2017.

Planning for this technology began when the hospital introduced digital mammography in 2012. Our administration and technologists understood that 3D mammography could eventually become a standard-of-care in breast imaging. In selecting a machine for mammography, the hospital chose one that would be easily compatible with 3D imaging.

What is a Mammogram?

Mammograms are used as a screening tool to detect early breast cancer in women experiencing no symptoms and to detect and diagnose breast disease in women experiencing symptoms such as a lump, pain or nipple discharge.

What is 3D Mammography?

From the National Cancer Institute:

Three-dimensional (3D) mammography, also known as digital breast tomosynthesis (DBT), is a type of digital mammography in which x-ray machines are used to take pictures of thin “slices” of the breast from different angles and computer software is used to reconstruct an image. This process is similar to how a computed tomography (CT) scanner produces images of structures inside of the body. 3D mammography uses very low dose x-rays, but, because it is generally performed at the same time as standard two-dimensional (2D) digital mammography, the radiation dose is higher than that of standard mammography. Newer tomosynthesis strategies allow DBT to be done alone, potentially reducing the radiation dose to a level closer to that of standard mammography.

Current Mammography Guidelines

Current guidelines from the American Cancer Society (ACS), and the American College of Radiology (ACR) recommend screening mammography every year for women, beginning at age 40.

Our Mammography Equipment

The Digital Mammography unit, equipped with Computer-Aided Detection (CAD), gives Bertrand Chaffee Hospital the technology for diagnosing breast cancer.  CAD is an advance in the field of breast imaging. If the computer software detects any breast abnormalities or “regions of interest” on the mammogram image, it marks them. The radiologist can then review the images to determine whether the marked areas are suspicious and require further examination.


Our facility is accredited by the American College of Radiology (ACR) and the U.S. Food and Drug Administration (FDA).

Preparation for Mammography

  • 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.
  • Describe any breast symptoms or problems to the technologist performing the exam.
  • If possible, obtain prior mammograms and make them available to the radiologist at the time of the current exam.

Frequently Asked Questions

Do I have to bring any paperwork with me to my appointment?

Yes, a prescription from your physician is required for Mammography.

Also a Mammography questionnaire must be filled out at the time of your exam.  Please click here to download the questionnaire.  Please print, complete and bring with you on the day of your appointment.

Do I need an appointment?

Yes, an appointment is necessary for your Mammogram. We offer day and evening appointments for your busy schedules.  The newly renovated Mammography suite enhances your visit.

Will I get my results right away?

After your Mammogram is complete, the technologist will view the images with the Radiologist.  You will be given a written report from the Radiologist, and a typed report will be sent to your physician to discuss the results further with you.  If your appointment is in the evening, the written report will be sent to you by mail.

If you have any questions concerning your Mammogram, please feel free to ask your provider or members of the imaging staff.
