Retrospectively, we compare synthesized 2D Mammograms combined with Digital Breast Tomosynthesis versus combination-mode imaging which include 2D Digital Full Field Mammography (DFFM) combined with Tomosynthesis.

Two expert radiologists assessed 100 mammograms retrospectively in two different ways. The first aspect of interpretation consisted in using 3D Digital Tomosynthesis combined with 2D DFFM and the second one included 3D Tomosynthesis combined with reconstructed synthetic 2D Mammography. In both cases previous mammograms were provided and reviewed. All 100 mammograms were positive for some kind of findings; 69 patients were placed under BIRADS 2 category which showed lesions stable for two years, the rest 31 patients were classified as BIRADS 3, 4 or 5 with a proper histological correlation.

-In 97 cases nodules, microcalcifications and architectural distortions were diagnosed by both imaging techniques. - In 2 cases, the architectural distortion was the main finding and could only be detected with Digital 3D Tomosynthesis. - In 1 case, the architectural distortion was visualized on synthesized 2D Mammography and Tomosynthesis but not on conventional DFFM. -Most sites of architectural distortion, nodule´s contours and calcifications were more visible with synthesized 2D Mammography than DFFM - Our radiologists felt more confident in the detection of microcalcification and architectural distortion using the synthetic mode of imaging. -The use of synthesized 2D Mammography improves the characterization of the lesions compared to FDDM

- Synthesized 2D Mammography has at least the same sensitivity as the conventional 2D mammography. -More clinical trials are needed to evaluate better the specificity of the synthesized 2D mammography in different kind of lesions. -As other studies show, Digital Breast Tomosynthesis combined with 2D Mammography has better sensitivity than 2D Mammography alone.

Digital 3D Breast Tomosynthesis and Synthesized 2D Mammography increase the mammograms’ sensitivity and decrease the radiation dose compared to conventional 2D mammography and Tomosynthesis.
