3D-Mammographie (Digitale Brust-Tomosynthese)

Digital breast tomosynthesis, often called 3D mammography, is an advanced form of mammogram. The X-ray tube sweeps in a short arc over the compressed breast, taking multiple low-dose images that a computer reconstructs into thin slices of about 1 mm. The radiologist scrolls through the slices instead of viewing one flattened picture.

Looking slice by slice reduces the problem of overlapping tissue hiding a cancer or imitating one. In screening studies it finds roughly 1 to 3 additional cancers per 1,000 women and lowers recall for false alarms in many programmes. Whether this leads to fewer deaths than standard mammography has not yet been proven, and it still misses some cancers in very dense breasts.

What 3D Mammography (Digital Breast Tomosynthesis) shows

Tomosynthesis shows masses, areas of architectural distortion, asymmetries and microcalcifications. It is particularly good at revealing small spiculated masses and distortion that are hidden by overlapping glandular tissue, and at demonstrating that an apparent abnormality on a 2D image was only superimposed normal tissue. Findings are graded with the BI-RADS scale from 0 to 6, and breast density is reported in categories A to D. Many systems also generate a synthetic 2D image from the 3D data, so a separate standard exposure is unnecessary. It does not show blood flow or tumour activity, and it cannot by itself tell benign from malignant: suspicious findings still need ultrasound and a biopsy.

When 3D Mammography (Digital Breast Tomosynthesis) is recommended

• Routine screening from age 40 to 50 onwards, according to your national guidance, every 1 to 2 years
• Women with heterogeneously dense breasts (category C), where the advantage over 2D is greatest
• Recall after an unclear 2D screening mammogram
• Assessment of a lump, nipple change or localised pain, together with ultrasound
• Follow-up after breast cancer treatment

Grenzen und Situationen, in denen ein anderer Test besser ist:

• Women under about 30 to 35 with a lump, for whom ultrasound is the first test
• Pregnancy, unless clearly necessary; ultrasound is preferred
• Extremely dense breasts or high genetic risk (for example BRCA carriers), where MRI adds far more
• It does not replace biopsy when a finding is suspicious

Wie man sich vorbereitet

• If you still have periods, book for the week after your period, when breasts are less tender
• Do not use deodorant, talc or lotion on the chest or underarms that day, because they can mimic calcifications
• Wear a two-piece outfit
• Bring previous mammograms on disc or via a link; comparison with old images is one of the most useful things a radiologist has
• Mention breast implants, previous surgery, hormone therapy and any chance of pregnancy

Was passiert während des Tests

You undress to the waist and stand at the machine. A radiographer positions each breast in turn on the plate and lowers a clear paddle to compress it for about 10 to 15 seconds while the tube moves in an arc overhead. Two views of each breast are taken. Compression is uncomfortable and sometimes briefly painful, but it is needed for sharp images and a lower dose. The appointment takes 15 to 20 minutes. The radiation dose is similar to or slightly higher than a standard mammogram and is well within safety limits.

Ergebnisse und nächste Schritte

In a diagnostic clinic, the radiologist often reads the images the same day and can add an ultrasound at once if needed. Written screening reports take 1 to 3 days. BI-RADS 1 and 2 mean routine screening, BI-RADS 3 means a short-interval recheck at 6 months, BI-RADS 0 means more imaging is needed, and BI-RADS 4 or 5 means a needle biopsy is advised. Ask for a copy of the images to take home.

• Test time: 15 to 20 minutes
• Results ready: Same day to 3 days
• Zurück zur alltäglichen Aktivität: Keine

Sicherheit und Risiken

• Brief discomfort or pain from compression
• A small dose of radiation; the lifetime risk from screening doses is very low compared with the benefit from age 40 onwards
• False positives leading to extra imaging or a biopsy that turns out benign
• False negatives, particularly in dense breasts
• Overdiagnosis of slow-growing lesions that might never have caused harm

Arranging 3D Mammography (Digital Breast Tomosynthesis) in Türkiye

Nobody needs to fly for a mammogram. It fits well within a wider women's check-up during a visit, or when you want same-day reporting with ultrasound and biopsy available in one place. Bring previous images. If you screen regularly, staying with one centre or carrying your images with you helps comparison.
