What is 3D Tomosynthesis Mammography?


  • Tomosynthesis is a type of digital mammography system that can be used in the diagnosis of breast cancer. As it has a low radiation dose, tomosynthesis is becoming increasingly common and is preferred by imaging centers. Sonomed performs breast examinations using 3D tomosynthesis mammography.

    How Does 3D Tomosynthesis Mammography Work?

    In breast tomosynthesis, an X-ray tube moves in an arc, capturing multiple images of each breast from different angles. These digital images are then “synthesized” into three-dimensional images by a computer, minimizing tissue overlap that could obscure cancer cells.

    Early detection is important in tomosynthesis. Medical technologies for breast screening are constantly being updated, and tomosynthesis is considered a preferred method of examination for diagnosing breast cancer by experts. Through tomosynthesis, specialists can evaluate screening results in detail and make a diagnosis.

    3D Tomosynthesis Mammography Facilitates Diagnosis by Approximately 35% Especially in Cases Where Breast Density Is High.

    How Is Tomosynthesis Imaging Performed?

    Tomosynthesis breast screening follows the same processes as digital mammography. In this method, the patient’s breast is placed between two plastic layers, and fixation is done to prevent movement of the breast. The X-ray tube moves around the breast tissue, and the imaging process is completed within seconds. Results are sent to a digital environment as soon as imaging is complete, and the breast’s 3D images are prepared in the digital environment.

    The 3D images are effective in the specialist’s evaluation of the results. The use of tomosynthesis for breast cancer diagnosis is increasingly common and is used by many imaging centers and medical institutions.

    Tomosynthesis can be used for diagnosing breast cancer

    ⇒ In cases where it may be difficult to diagnose breast cancer with digital mammography, the detection rate of breast cancer is higher with tomosynthesis mammography.

    ⇒ Tomosynthesis mammography provides higher accuracy in determining the location, size, and shape of breast diseases.

    ⇒ Digital mammography and tomosynthesis mammography are performed on the same device. Mammography imaging can be carried out through the same process in devices where tomosynthesis is applied.

    ⇒ The accuracy of detecting multiple breast tumors is higher with tomosynthesis mammography.

    ⇒ Thanks to the 3D images obtained, there is a decrease in biopsy requests required in the diagnostic process.

    ⇒ Tomosynthesis provides success in detecting and identifying small tumors as well as large ones. It provides diagnostic opportunities for experts.

    ⇒ In terms of providing clear results, it enables the detection of the disease in early stages. Patients do not have to undergo mammography repeatedly and receive radiation.

    ⇒ Tomosynthesis mammography is effective in reducing biopsy and surgery rates. Early diagnosis and three-dimensional evaluation are effective in determining the course of the disease.
