Breast tomosynthesis: the new age of mammography tomosíntesis: la nueva era de la mamografía

Objective: to evaluate the available data of Breast tomosynthesis as a complementary tool of direct digital mammography. Methods: a systematic literature search of original and review articles through pubmed was performed. we reviewed the most important aspects of tomosynthesis in breast imaging: Results: 36 original articles, 13 review articles and the fda and american College of radiology standards were included. Breast tomosynthesis has showed a positive impact in breast cancer screening, improving the rate of cancer detection due to visualization of small lesions unseen in 2d (such as distortion of the architecture) and it has greater precision regarding tumor size. In addition, it improves the specificity of mammographic evaluation, decreasing the recall rate. limitations: interpretation time, cost and low sensitivity to calcifications. Conclusions: Breast tomosynthesis is a new complementary tool of digital mammography which has showed a positive impact in breast cancer diagnosis in comparison to the conventional 2d mammography. decreased recall rates could have significant impact in costs, early detection and a decrease in anxiety.
