Tomosynthesis views
Patient information factsheet
Why have I been recalled for extra imaging?
- The Consultants (specialist Doctors) who looked at your mammogram have seen an area that needs a closer check.
- The reason for this is that often a part of the breast looks denser (thicker) than the tissue around it.
- Extra images give more detail.
- They help check things like asymmetry (when one area looks different from another) or distortion (when the normal shape of the breast tissue looks unusual).
What are tomosynthesis views?
- Tomosynthesis images are 3D pictures of the breast.
- They are made using a special type of mammogram that takes many low-dose X-ray images from different angles.
- Each tomosynthesis image uses a low dose of radiation, and the total radiation dose from the examination is similar to that of a standard mammogram.
- It gives a clearer, slice-by-slice view of the breast tissue.
- It can help find abnormalities, especially in dense breasts. This is because superimposed breast tissue (overlapping tissue) can hide or look like a problem.
- Tomosynthesis views give a clearer, three-dimensional view of the breast and can help spot abnormalities that may be difficult to see on a standard mammogram alone.
What happens during this procedure?
- Being positioned for tomosynthesis is very similar to having a normal mammogram.
- The breast is compressed (pressed) for a few extra seconds to allow for all the images to be taken.
- The x-ray tube moves in a curve over the compressed breast but will not touch you.
- Once the imaging is completed, the plate will release the breast automatically.
What happens after the procedure?
- After the extra images are taken, your Consultants will review them.
- Your results will be ready within two weeks. If more tests are needed, the Breast Imaging team will call you.
