3-D Mammography at Putnam Hospital Center

Posted: 8/2/2017

The hospital’s Radiology Department now offers digital breast tomosynthesis, or 3-D mammography, bringing a new level of confidence and comfort to its patients.

“I’m really excited to bring this new tool in the fight against breast cancer to our patients,” said Dr. Donald Lien, associate director of radiology at Putnam Hospital Center. “3-D mammography offers greater clarity and accuracy in cancer detection over two-dimensional imaging.”

Research, Lien said, shows that 3-D mammography increases the detection of invasive cancers by 41 percent and decreases unnecessary callbacks for further testing by 40 percent.

The exam is similar to a conventional mammography but provides multiple 3-D images of breast tissue in one-millimeter layers. Radiologists view the images in a series of thin slices, allowing for finer detail and better visibility of overlapping breast tissue. The system is often used to screen patients with dense breasts.

The technology is FDA-approved for all women undergoing standard screening and diagnostic mammograms. Most insurance covers 3-D mammography.
