The latest advancement in breast imaging technology is Tomosynthesis or 3-D mammography, which improves the accuracy of breast cancer screening.

The new technology does not require any additional time from the woman being screened. Tomosynthesis is performed at the same time as a standard mammogram.

How Does It Work?

During the 3-D exam, a woman's breast is compressed, just as it is for a traditional mammogram. The x-ray machine moves over the breast, taking multiple, slice-like images. Special computer software then creates a detailed 3-D image, with a process that's similar to what a CT scanner does.

Who Can Benefit?

Anyone can benefit from the new technology. It will be especially beneficial for women with dense breast tissue and those with a high risk of breast cancer.

What Are the Benefits?

Using the 3-D images, doctors may:

  • Find tumors that may have remained hidden on a conventional, 2-D mammogram.
  • Reduce the number of women called back for additional testing for "false alarms."
  • Improve the ability to diagnose breast cancer earlier.
