INTRODUCTION: Increased mammographic breast density is a moderate independent risk factor for breast cancer.
The odds ratio for developing cancer for the most compared with the least dense breast tissue categories ranges from 1.8 to 6. Different classifications based on qualitative or quantitative criteria have been described.
One of the most common used is ACR (BIRADS) classification based on density categories.
 Digital mammography (2DM) remains the most commonly used procedure for...
Methods and materials
Patients selection From September 2013 to September 2014 we began to use the synthesized-DM and the COMBO mode (2D-DM + DBT).
A total number of 8201 consecutive COMBO studies were performed at our institution in a clinical setting.
Synthesized reconstruction images were obtained from all DBT studies. The informed consent was offered to all patients. All the studies were performed using a Selenia Dimensions unit (Hologic,
USA). Study design We retrospectively selected an enriched sample with...
The distribution of the ACR density patterns for first reader wasthe following: In both studies the percentage of patients with ACR a was the same. In synthesized-DM there was a decrease of 4.7 % of patients with ACR b and 3.6 % of patients with ACR c. However,
there was an increase of 8.3 % of patients with ACR d compared with 2D-DM. The intra-observer kappa index for this first reader was 0.809 so substantial or almost perfect agreement was found which was statistically significant...
1- Our results showed a trend to increase in ACR d density pattern when using synthesized-DM. 2- The intraobserver concordance was excellent for both readers. 3- The interobserver concordance was moderate for both techniques although slightly better for synthesized-DM.
