SUMMARY
Objectives: To improve the image acquisition method, increase the chances of pathological findings and clarify inconclusive diagnoses. Methodology The mammography is the most effective method for prevention and diagnosis purposes. To promote the findings and enhance the imaging, researchers have developed a new technology acquisition, tomosynthesis, a procedure that has been increasing detection methods with sophisticated computer use allows better accuracy in relation to the degree of density factor. 3D mammography works with the reconstruction of signals in the formation of two-dimensional images captured at different angles to the displacement of the gantry on the basis of various heights inside the breast, relating to the detector with different spatial projection together with the objective to bring better results in the fight against breast cancer. The tomosynthesis captures the sectional images at various angles generating fine cuts, which decreases any possibility of overlapping structures, dissociating the tissues and acquiring image cleaner according fatty breast tissue. The indication of tomosynthesis is associated with traditional mammography resulting in an examination with higher resolution and clarity, preventing false-positive or recalls. Results Combined Digital Mammography (MDC) is especially suitable for dense breasts, in which the sequential acquisition of images allows to visualize tumors not calcified with asymmetrical features, architectural distortions and spiculated nodules. Images shot allows better definition of the edges of lesions, increases the subtle detections and provides the exact spatial location of the lesion. Conclusion It is known that the tomosynthesis is an innovative method incorporated into the mammogram is considered one of the most important currently. The results of the techniques has been satisfactory and its use has demonstrated an increase in pathological findings bringing greater clarity and decreasing the indication of biopsies and additions.
