What is 3D Mammography?

3D mammography, also known as digital breast tomosynthesis (DBT), is a type of advanced X-ray imaging that creates detailed three-dimensional pictures of the breast tissue. Unlike traditional 2D mammograms, which capture flat images, 3D mammography takes multiple images from different angles, allowing radiologists to see the breast tissue layer by layer.

Why Choose 3D Mammography?

• Early Detection: 3D mammograms can detect breast cancer earlier, especially in women with dense breast tissue.
• Reduced False Alarms: 3D mammograms may lead to fewer unnecessary biopsies due to better visualization of suspicious findings.
• Improved Accuracy: The 3D view allows radiologists to see details that might be obscured in a 2D image, leading to a more accurate diagnosis.

How Does 3D Mammography Work?

During a 3D mammogram, you stand at a machine and your breast is compressed between two paddles. The machine then moves in an arc around your breast, taking multiple low-dose X-ray images. These images are then combined to create a 3D reconstruction of your breast tissue.

Advantages of 3D Mammography:

• Higher cancer detection rates
• Fewer false alarms
• Improved accuracy in diagnosis
• May be particularly beneficial for women with dense breast tissue

Disadvantages of 3D Mammography:

• Slightly higher radiation dose compared to a traditional mammogram (though still considered safe)
• May be more expensive than a traditional mammogram (check with your insurance provider)
• Not yet as widely available as traditional mammograms
