3D Mammogram: What You Need To Know
3D Mammogram Overview: Purpose, Advantages, and Limitations
A 3D mammogram, also known as digital breast tomosynthesis (DBT), is a test for breast cancer utilizing X-rays to create detailed images of the breasts. This method is employed to detect early signs of cancer.
The advantages of this method include:
- Clearer images compared to traditional 2D mammography, which reduces false positives and unnecessary biopsies.
- More effective at identifying cancer in dense breasts than regular 2D tests.
However, there are limitations:
- Allergic reactions or other side effects from the contrast dye used during DBT exams may occur.
- Discomfort due to pressure on the breasts during the exam is another potential limitation.
Numerous studies are currently examining ways to further improve DBT scans.

Preparing for a 3D Mammogram: Procedure and Interpretation of Results
Preparing for a 3D mammogram involves:
- Avoiding the use of deodorants, body powders, or lotions on the chest on the day of the exam, as these substances can interfere with image quality.
- Wearing two-piece clothing is beneficial, as it allows for the removal of only the top and bra.
The procedure involves a radiology technician placing one breast at a time on a special platform. The machine then takes multiple images from different angles while compressing the breast. This process is usually painless but may cause mild discomfort briefly.
The interpretation of results occurs after the scanning process. The computer generates detailed images for each slice of breast tissue, akin to pages in a book. This technique aids in the identification of tiny tumors that might be obscured in dense breasts during traditional mammograms.
Negative results indicate that no abnormal cells are found, whereas positive results suggest the presence of something suspicious, necessitating further testing. However, a positive result does not necessarily indicate cancer.
Clinical Trials and Patient Stories on 3D Mammograms: Kathleen Stewart's Experience
Kathleen Stewart is a breast cancer survivor who attributes her survival to 3D mammograms. These tests produce multiple clear images of the breast, providing better detection capabilities than traditional mammograms.
Stewart was part of a clinical trial for 3D mammograms at Johns Hopkins Medical Centre. The trial aimed to assess the effectiveness of these scans in detecting early-stage cancers in comparison with regular 2D scans. Her tumor was discovered at stage I, indicating the advanced technology's potential in early detection.
Her experience highlights the role of clinical trials in the progress of medical knowledge and patient care, showcasing the contribution patients can make to healthcare by participating in such studies.
