Purpose:

The aim of this retrospective study is to demonstrate the diagnostic significance of digital mammography with tomosynthesis (3D) versus digital mammography alone (2D) in women with histologycally proven breast cancer according to the breast density.

Materials-Methods:

A group of 125 women were examined for this study, with clinical findings, ultrasonography or 2D mammography showing suspicious breast lesions. All of these patients were sent to the Institute of Oncology for further examination and biopsies. Aterer the initial clinical breast exam, 2D and 2D/3D mammographies were performed. Digital mammographies were performed using a Selenia Dimensions Unit allowing 2D/3D mammography to be obtained via the COMBO procedure (Hologic). This gives 2D and 3D images at the same as a diagnostic examination. The 2D and 3D acquisitions consisted of a double view (MLO and CC) mammography. In accordance with the ACR breast density pattern, we divided the patients in two groups: a low-density (ACR1 and 2) and a high-density group (ACR3 and 4).

Results:

Table 1 shows comparative parametars between two mammographies (2D and 2D plus 3D) in two breast density categories (low and high breast density).

Conclusion:

The authors concluded that use of 3D in combination with 2D mammography improves  breast cancer detection in women with dense breasts.
