3D mammograms, or Digital Breast Tomosynthesis (DBT), are breast cancer screening technologies that take multiple breast X-ray angles and combine them into a 3D image. This allows doctors to clearly see each tissue layer — 20-65% more accurate than traditional 2D mammograms in detecting early-stage cancer. Numarak Hospital provides 3D mammograms using the Hologic 3Dimensions® machine in conjunction with Genius AI® Detection, which utilizes artificial intelligence to interpret results for maximum accuracy in breast cancer screening.
What is a 3D mammogram?
3D mammogram, or medically known as Digital Breast Tomosynthesis (DBT), is a new form of breast X-ray examination developed from the traditional 2D mammogram. It uses a moving X-ray machine in a curved position above the breast, taking multiple images from different angles.
The resulting images are processed by a computer to create a 3D image that allows the breast tissue to be viewed in layers (slices), each approximately 1 millimeter thick. This allows the doctor to easily view each layer of tissue, much like turning the pages of a book — reducing the problem of overlapping tissues obscuring the view.
The Hologic 3Dimensions machine used at Namarak Hospital can complete a scan in just 3.7 seconds per side, reducing the time patients need to compress their breasts and providing greater comfort compared to older models.
What are the differences between a 3D mammogram and a 2D mammogram?
The clear advantages of 3D mammograms.
Early detection of cancer is higher — Invasive Ductal Carcinoma, the most common type, is detected with 20-65% (average +41%) accuracy.
Reduce unnecessary repeat tests by 30-40% — reducing both patient stress and additional costs.
This is suitable for Asian women with dense breasts , a group that is difficult for 2D mammograms to detect.
Reducing overlapping tissue is a major reason why cancer is not detected.
Scanning time is just 3.7 seconds per eye — no increase in radiation dose (using C-View synthesized 2D).
Hologic Genius 3D + AI: The technology chosen by Namarak.
Numarak Hospital decided to invest in the Hologic 3Dimensions Mammography System , a premium-tier 3D mammogram machine used in leading hospitals worldwide, including those in the US News & World Report's Top 20 Cancer Hospitals list.
Key features of the Hologic 3Dimensions machine.
1. SmartCurve Compression Paddle
Breast compression pads, curved to conform to the natural shape of the breast, reduce breast compression pain during examination by up to 93% compared to flat compression pads.
2. Genius 3D Mammography Exam
The tomosynthesis imaging system has been clinically proven to detect invasive breast cancer 20-65% more often than conventional 2D mammograms.
3. C-View Technology
Creating 2D images from 3D data eliminates the need for additional 2D imaging— reducing patient radiation exposure while maintaining diagnostic quality.
Genius AI® Detection: Artificial intelligence helps read the results.
The Hologic device at Namarak is enhanced with Genius AI Detection , an FDA-approved artificial intelligence software that assists in reading 3D mammogram images, achieving a high sensitivity of 94% in detecting lesions.
Recent research from Massachusetts General Hospital (MGH) in 2025, which studied 7,500 tomosynthesis images, found that:
Genius AI can detect 32% of cancer cases that doctors misread during the initial examination (false negatives).
90% of cancers detected and located by doctors have now been successfully identified.
It is particularly effective in detecting invasive ductal carcinoma and cancer that has spread to the lymph nodes.
In short: AI acts as a second assistant for radiologists — helping to prevent the missed lesions that might otherwise be overlooked.
Who should have a 3D mammogram, and when?
According to the guidelines of the NCCN (National Comprehensive Cancer Network) and the National Cancer Institute:
Women aged 40 and older — screen every 1-2 years.
Women aged 35-39 years — at least one test for baseline status.
Women with a family history of breast cancer should begin screening at a age 10 years younger than their direct relatives who have had cancer.
Individuals at high risk — for example, those with BRCA1/BRCA2 genes, or a history of radiation therapy to the chest.
For women with dense breasts , 3D mammograms are significantly more suitable than 2D ones.
Examination procedures and preparation.
Before the examination.
No need to fast or dehydrate.
Do not apply powder, lotion, or perfume to the breasts and armpits on the day of the examination.
Wear easy-to-remove clothing — two-piece outfits are recommended.
The ideal time for women who still have menstruation is 5-10 days after the first day of their period.
Please bring your previous test results (if available) for comparison.
During the examination.
Change into the hospital gown → Radiography technician positions and places the breast on the machine → SmartCurve pad gently compresses the breast → Takes two standard images per side (CC and MLO), taking only 3.7 seconds per side.
Total examination time: 15-20 minutes.
After the examination
You can return to your normal activities immediately.
The test results will be available within 1-3 business days (radiologist reads the results + AI assistance in verification).
If further tests are required (Ultrasound, MRI, or Biopsy), the medical team will schedule them for the same day at Namarak — a one-stop shop for all your medical needs.
Reading BI-RADS test results.
The results are interpreted using the internationally standardized BI-RADS (Breast Imaging Reporting and Data System) , which is divided into 7 levels, from BI-RADS 0 (further testing required) to BI-RADS 6 (cancerous confirmed).
BI-RADS 0 : Further testing (ultrasound or additional imaging) is required.
BI-RADS 1-2 : Normal — Routine checkup as per schedule.
BI-RADS 3 : Likely not cancer (< 2%) — Retest in 6 months.
BI-RADS 4-5 : Suspected cancer — Biopsy required.
BI-RADS 6 : Cancer confirmed — Treatment plan in place.
The doctor will explain the results and provide personalized advice — don't worry about the numbers alone.

Frequently Asked Questions (FAQ)
Does a 3D mammogram hurt?
Breast compression during an examination may feel slightly firm or uncomfortable, but it is not usually painful. The Hologic machine at Namarak uses SmartCurve compression pads that reduce discomfort by up to 93% compared to traditional flat pads. Furthermore, the compression time per side is only 3.7 seconds.
How long does a 3D mammogram take?
The actual examination takes about 15-20 minutes, including changing gowns, positioning, and taking four standard images (two on each side). If an ultrasound examination is also required, it will add another 15-20 minutes.
Do 3D mammograms and ultrasounds need to be done together?
Depending on individual breast characteristics and risk factors, women with dense breasts or a family history of breast cancer are generally recommended to have both examinations, as 3D mammograms and ultrasounds detect lesions differently.
Is having mammograms too frequently an risk factor for radiation exposure?
The radiation dose from modern mammograms is very low, around 0.4 mSv per examination. Mammograms, as recommended by your doctor, are safe, and the benefits of early cancer screening far outweigh the radiation risks.
Can people under 40 years old get tested?
Women under 40 generally don't need routine 3D mammograms because their breasts still have dense tissue, making images difficult to read. Doctors often recommend breast ultrasound instead. However, if you experience any abnormalities or have a high-risk profile, you should consult your doctor for individual consideration.
When will I know the test results?
3D mammogram results at Namarak Hospital will be available within 1-3 business days. Radiologists will interpret the images using the AI Genius® Detection system. In emergency cases or when symptoms are suspicious, the medical team can provide same-day results.
Is AI more accurate than a real doctor's diagnosis?
AI doesn't replace doctors, but functions as a second assistant for radiologists. Research from Massachusetts General Hospital in 2025 found that Genius AI Detection detected lesions that doctors initially misread 32% of the time — demonstrating that AI improves accuracy when used in conjunction with doctors.
