About 3D Mammograms – Tomosynthesis

Mammograms are radiologic images of the breasts, created by low-dose x-rays.

Tomosynthesis, often called 3D mammography, is the latest technology.

These specialized images may reveal breast changes before a woman or her doctor is able to feel or see them. When changes indicating cancer are detected by mammography, treatment may begin sooner and chances for success are better.

Because we are committed to providing early detection of breast cancer, Abington Jefferson Health uses only 3D mammography at the Mary T. Sachs Breast Center and all other locations where we offer mammograms (Abington Health Center – Blue Bell, Abington Health Center – Warminster, and Abington – Lansdale Hospital). The advancements of tomosynthesis help us achieve the most accurate screenings and diagnoses.

3D mammography differs from conventional digital mammography in several important ways:

  • It allows the breast to be viewed as a computer generated set of images. Multiple images are reconstructed from a series of low-dose exposures. These images are obtained during the same compression as previous standard two-dimensional mammographic views. This combination of obtaining two dimensional and tomosynthesis images together is quick; most people will not experience any difference between traditional digital mammography and tomosynthesis.
  • Differences in abnormal tissue that might not be noted on a conventional digital mammogram can often be identified on a tomosynthesis mammogram.
  • Abnormalities are harder to see on mammograms of dense breast tissue. Research has shown that 3D mammograms are more sensitive and accurate for women with dense tissue. Breasts are considered dense when they have more connective and glandular tissue and less fat. Women of all ages may have dense breasts.

Radiologists can magnify, enhance or adjust the 3D mammogram image for greater clarity. We also utilize computer-aided detection (CAD), a sophisticated software program, to enhance our mammogram readings.

The procedure for having a 3D mammogram is the same as for a conventional digital mammogram. Our breast imaging services are offered in comforting surroundings, with warm and caring technologists and radiologists. These professionals are happy to answer your questions and ease any concerns you may have.
