Purpose
Introduction
Digital mammography remains the most commonly used procedure for mammographic screening because it has demonstrated to reduce the mortality rate for breast cancer.
But many limitations are recognized,
in particular the issue of overlapping imaged tissue that can miss around 20% of breast cancers or can mimic abnormalities,
generating false positive results.
Tomosynthesis is a three-dimensional examination whose goal is to minimize the effects of structure overlap with improvement in both sensitivity and specificity from mammography.
Synthesized digital mammography (Synthesized-DM) is a reconstructed synthetically generated image,
from the information acquired during digital breast tomosynthesis (DBT).
The main advantage of using Synthesized-DM instead of 2D-DM is to reduce the woman exposure radiation,
because the conventional 2D-DM is not needed.
It has been recently published in the literature that using synthesized-DM images with DBT reduced women's exposure radiation by 45%,
compared with using DBT and conventional mammography(COMBO MODE).
Purpose
The aim of this study was to compare the diagnostic performance of both techniques,
conventional Digital Mammography (2D-DM) and Synthesized Digital Mammography (3D-DM).
