Derry Imaging is pleased to offer our patients the most advanced mammography technology available today performed in our friendly and comfortable surroundings at all of our facilities.

Is this your first (baseline) mammogram? Click here.

3D mammogram™ exams are included as part of your annual screening at no extra charge at Derry Imaging, even if your insurance will not cover the cost of a 3D mammogram™. We believe that 3D mammography™ technology is the standard of care, and every woman should have access to this advanced technology.



Our comprehensive 3D mammography™ system enables us to provide the highest resolution and fastest results for annual screenings and diagnostic mammograms. Plus, 3D Mammography™ (breast tomosynthesis) ensures that our patients continue to have access to the best cutting edge technologies around.

And, with our latest addition of Volpara Enterprise software, our breast care team can better assess your breast density and ensure each image in your mammogram is of the highest quality possible.

Why is image quality important for my mammogram?

Having high-quality images makes it easier for our radiologists to find cancer. VolparaLive! uses artificial intelligence to help the technologist monitor image quality each and every time, ensuring you receive the best mammogram possible. We use VolparaLive! at all of our locations in addition to Volpara Density.

The American College of Radiology, the American College of Obstetricians and Gynecologists and the Society of Breast Imaging all recommend that women 40 and older should have a mammogram every year. Variations of this schedule may occur if your medical history and condition requires a different frequency. Early diagnosis and treatment significantly improves a patient’s chance for a successful recovery from breast cancer.

Early Detection is Key!

What is a 3D mammogram™?

3D Tomosynthesis "slices"

Breast Tomosynthesis uses high-powered computing to convert digital breast images into a stack of very thin layers, or “slices”, building what is essentially a 3-dimensional mammogram. The imaging machine moves around the breast in an arc, taking multiple x-rays that a computer forms into a 3D™ image of your breast tissue in one-millimeter slices. This produces the greatest visibility for the radiologist, who can scroll throughout images of your entire breast like pages of a book. Just as with a standard mammogram, compression is required for the 3D™ part of the exam.

What are the benefits of 3D mammography™?

With conventional digital mammography, the radiologist is viewing all the complexities of your breast tissue in one flat image.  2D to 3D Comparison Sometimes breast tissue can overlap, giving the illusion that normal breast tissue looks like an abnormal area. By looking at breast tissue in one millimeter slices, the radiologist can provide a more confident assessment. As a result, there may be fewer callbacks for secondary screenings.

What should I expect during the 3D mammography™ exam?

Selenia Dimensions Breast Tomosynthesis system

3D mammography™ complements standard 2D mammography and is performed at the same time with the same system. During the tomosynthesis portion of the exam, your breast will be under compression while the x-ray arm of the mammography machine makes a quick arc over the breast, taking a series of breast images at a number of angles. There is no extra compression required, and it only takes a few seconds longer for each view.


Is there more radiation dose?

Very low X-ray energy is used during the exam, just about the same amount as a traditional mammogram done on film.  3D Mammograms™ and Radiation
