A 3D mammogram, or tomosynthesis, takes many low-dose images of the breast from different angles to build thin layers. It can make it easier to see through dense breast tissue.
Also called: Tomosynthesis, Breast tomosynthesis, DBT, 3D breast X-ray

What is a 3D mammogram?
In tomosynthesis, the X-ray tube sweeps in a small arc over the compressed breast, taking a series of images that are reconstructed into thin slices. The radiologist scrolls through the slices, so overlapping tissue is less likely to hide something or look suspicious.
For you, it feels very similar to a standard mammogram. The breast is compressed in the same way, and each view takes a few seconds longer. It is often combined with standard 2D images or a synthesised 2D image.
Tomosynthesis can reduce call-backs and may help in dense breasts, but it is not available at every clinic. Radly only shows clinics that list it.
Why your doctor might request a 3D mammogram
- Investigating a breast symptom or abnormal finding
- Dense breast tissue on a previous mammogram
- Clarifying an area that looked unclear on 2D mammography
- Higher-risk follow-up as advised by a specialist
3D mammogram: preparation, referral & Medicare

- Wear a two-piece outfit.
- Bring previous breast imaging for comparison.
- Tell the staff if you have implants, are pregnant or breastfeeding.
How long it takes: About 20–40 minutes
Referral, Medicare & bulk billing
A 3D mammogram at a private clinic needs a referral from your GP or specialist. Medicare rebates for mammography depend on the item your doctor requests, and the extra tomosynthesis component may not be covered, so billing varies. The clinic confirms billing when it confirms your booking request.

3D mammogram FAQs
Is a 3D mammogram better than a standard mammogram?
It can improve detection and reduce call-backs, especially in dense breasts. Your doctor can advise whether it suits you.
Does a 3D mammogram use more radiation?
The dose is similar to or a little higher than a standard mammogram, and still low.
Does tomosynthesis feel different?
Not really. Compression is the same; each image just takes a few extra seconds while the tube moves.
