Results or findings

In our patients cohort we demonstrated that, the study in Mammography mode, with only four projections with prosthesis included, with standard exposure meter, is associated with an average glandular dose of 7.5 mGy. If the Eklund maneuver is also performed in Tomosynthesis mode, the woman is exposed to an average of 11 mGy in total. A low-dose configuration of the AEC, is associated instead with an average glandular dose equal to 9.2 mGy total. This configuration allowed a maximum amount of radiographic information currently possible, lowering the dose by 15 %, while maintaining adequate image quality.

At the present time, Tomosynthesis for the study of breasts with implants is not considered a valid diagnostic test yet, mainly due to the encumbrance of the prosthesis. However, the results of this test seem to highlight the possibility to use it effectively.
