Digital Mammography with 3D Tomosynthesis

Digital mammography with 3D tomosynthesis features advanced three-dimensional imaging, where the breast is imaged from multiple angles. These images are reconstructed into thin slices, typically 1 mm thick, enabling radiologists to examine the tissue layer by layer. This improves visibility and helps identify abnormalities that may be hidden in overlapping tissues in standard 2D mammograms.

One of its key strengths is improved cancer detection, especially for small or early-stage tumors. By providing clearer views of breast structures, it enhances diagnostic accuracy and supports earlier intervention when cancer is present.

This technology significantly reduces false positives by minimizing the confusion caused by overlapping normal tissues. As a result, it lowers the number of unnecessary follow-up exams, biopsies, or additional imaging that may cause anxiety for patients.

It is particularly effective for women with dense breast tissue, where traditional mammography is less accurate. The layer-by-layer imaging makes it easier to distinguish between benign and suspicious areas within dense tissue.

Images are digitally stored and enhanced, allowing radiologists to zoom in, adjust contrast, and share results quickly with other specialists if needed. This improves workflow and facilitates multidisciplinary collaboration.

Digital mammography with 3D tomosynthesis is applied in a clinical imaging center or hospital radiology department by trained radiologic technologists. The patient is typically asked to undress from the waist up and wear a gown that opens in the front. Any jewelry or powders that could interfere with imaging are removed beforehand.

The patient stands in front of the 3D mammography machine, and one breast at a time is placed on a flat support platform. A compression paddle gently presses the breast to flatten the tissue. This ensures even thickness, reduces motion, and improves image quality while using the lowest radiation dose possible.

While the breast is compressed, the X-ray tube moves in an arc around the breast, capturing a series of images from different angles. This process only takes a few seconds. The same steps are repeated for the other breast, usually in both craniocaudal (top-down) and mediolateral oblique (angled side) views.

After image acquisition, the data is reconstructed by a computer into thin, high-resolution slices. A radiologist later reviews the images on a specialized workstation, examining the breast tissue layer by layer for any abnormalities.
