Diagnostic Imaging

Mammography with Tomosynthesis

At the IGEA Nursing Home, a multidisciplinary team composed of a breast specialist, radiologist, pathologist, geneticist, and oncologist works to provide patients with an accurate diagnosis of breast pathologies and, where necessary, appropriate therapeutic and surgical procedures.

Tomosynthesis mammography , also known as 3D mammography or digital tomosynthesis mammography , is an advanced diagnostic imaging technique that allows for an accurate study of the breast and its internal structures.

What is tomosynthesis mammography?

Breast tomosynthesis uses low-dose X-rays and an advanced digital system capable of acquiring multiple images of the breast from different angles. These are reconstructed into a three-dimensional model, providing a true breast tomography.

With this approach, the radiologist can examine the breast layer by layer and identify nodules, microcalcifications, or small lesions that may not be visible with a conventional mammogram.

What is the difference between mammography and tomosynthesis mammography?

Traditional mammography provides a two-dimensional image, while tomosynthesis mammography generates a three-dimensional reconstruction.

This difference allows for a more accurate assessment, reducing the risk of tissue overlap. It is particularly useful in women with dense breasts , where any abnormalities may be less obvious.

How is a tomosynthesis mammogram performed?

The exam is performed similarly to a traditional mammogram. The patient is positioned in front of the machine and her breast is gently compressed to allow for proper image acquisition.

The X-ray tube moves in an arc, acquiring different projections. Software processes the images and reconstructs them in 3D, allowing the radiologist to analyze every single layer of the breast.

When should you have a tomosynthesis mammogram?

This type of 3D mammography may be indicated in several cases:

as a screening test for the early diagnosis of breast cancer;
in the presence of a family history of oncological pathologies;
to investigate a questionable result that emerged with a traditional mammogram;
in women with dense breasts or previously diagnosed breast changes.

The most appropriate time to undergo the test must be discussed with a specialist doctor, based on age, risk factors, and personal medical history.

What are the advantages of digital mammography with 3D tomosynthesis?

The main advantages of 3D digital mammography are:

higher image definition thanks to volumetric reconstruction;
early detection of nodules or microcalcifications;
reduction of recalls for in-depth examinations;
high reliability in screening, even in the presence of dense breast tissue.

These characteristics make breast tomosynthesis an important aid in the diagnosis and prevention of breast cancer.

How long does a tomosynthesis mammogram take?

The overall duration of the exam is short. On average, image acquisition takes about 4 seconds for each breast.

Is tomosynthesis mammography painful?

The exam is not painful, although it may cause some mild discomfort due to breast compression. This discomfort is temporary, lasting a few seconds, and most patients tolerate it without difficulty.

How does a mammogram work?

The clinic has a state-of-the-art mammogram dedicated to breast examinations. In addition to 2D digital mammography , the equipment also allows for 3D tomosynthesis examinations , providing high-resolution images for more precise assessments.

The service has been integrated with the AFFIRM system – 2D vertical stereotactic and Tomo Biopsy , dedicated to targeted breast biopsies . This technology allows sampling of lesions that are not palpable or visible on ultrasound, allowing for a more accurate assessment.

Conclusions

Mammography with tomosynthesis is an advanced technique that represents an important support tool for the early diagnosis of breast cancer.

Casa di Cura IGEA is also accredited by the Lombardy Region for mammography screening , a prevention program that allows for the identification of breast cancer in its early stages and timely access to appropriate treatment pathways.
