Three-dimensional digital mammography, also known as digital breast tomosynthesis (DBT), is a relatively new medical imaging technology that has several benefits over traditional two-dimensional mammography.

DBT is a type of mammogram that creates a 3D image of the breast, allowing for a more detailed view of the breast tissue. In this article, we will discuss the benefits of three-dimensional digital mammography over traditional two-dimensional mammography.

1. Better Detection Rates

The primary benefit of digital breast tomosynthesis is that it has been shown to increase cancer detection rates. In one study, DBT was found to increase detection rates by approximately 40% when compared to traditional mammography.

This is because the 3D image allows radiologists to see through the overlapping breast tissue that can cause cancers to hide in traditional mammography.

2. Fewer False Positives

False positives occur when a mammogram indicates the presence of cancer when there is actually no cancer present.

Traditional mammography is known for producing a high number of false positives, which can lead to unnecessary biopsies and anxiety for patients. Digital breast tomosynthesis, on the other hand, has been shown to reduce false positives by up to 40%. This means that women are less likely to be called back for additional testing or biopsy when there is actually no cancer present.

3. Earlier Detection of Breast Cancer

Because digital breast tomosynthesis is better at detecting breast cancer, it can also help detect cancer at an earlier stage. Early detection is important because it can lead to better treatment outcomes and a higher chance of cure.

Additionally, when breast cancer is detected early, less invasive treatments may be necessary.

4. More Comfortable for Patients

Digital breast tomosynthesis is also more comfortable for patients than traditional mammography. This is because the imaging process is faster and requires less compression of the breast tissue.

Additionally, because the images are taken at different angles, there is less need for patients to hold uncomfortable positions during the imaging process.

5. Lower Radiation Dose

The radiation dose from digital breast tomosynthesis is slightly higher than traditional mammography, but still well within safe limits.

Additionally, because the images are taken in a shorter amount of time, the overall radiation dose is lower than that of a traditional mammogram taken at multiple angles.

6. Improved Image Quality

Because digital breast tomosynthesis creates a 3D image of the breast, it allows for a more detailed view of the breast tissue. This can lead to improved image quality, which can help radiologists identify abnormalities more easily.

Additionally, because the images are digital, they can be manipulated for better visualization of the breast tissue.

7. Easier to Interpret Results

Because digital breast tomosynthesis produces a series of images, it can make it easier for radiologists to interpret the results. With traditional mammography, multiple images are taken at different angles, which can make interpretation more difficult.

By creating a 3D image of the breast, digital breast tomosynthesis can provide a more comprehensive view of the breast tissue.

8. Suitable for All Women

Women of all ages and breast types can benefit from digital breast tomosynthesis. While traditional mammography may be less effective for women with dense breast tissue, DBT has been shown to be effective for all types of breast tissue.

9. Cost Effective

While the initial cost of digital breast tomosynthesis may be higher than traditional mammography, it is more cost-effective in the long run. This is because DBT reduces the need for additional imaging and biopsies, which can be expensive.

10. Improves Patient Outcomes

Ultimately, the primary benefit of digital breast tomosynthesis is that it can improve patient outcomes. By increasing cancer detection rates, detecting cancer at an earlier stage, and reducing the number of false positives, DBT can help save lives.

Additionally, by being more comfortable for patients and easier to interpret for radiologists, DBT can lead to a better overall patient experience.
