Methods and materials
This is an observational study in a clinical setting (non-academic institution) with a retrospective analysis of 6.
614 breast screening exams,
which included FFDM,
DBT and BUS,
from January 2012 to December 2015.
Most of the BUS and DBT exams were done by the same physician,
on the same day as part of our standard protocol. The study was approved by the institution's research ethics committee
Inclusion criteria:
- Asymptomatic women with negative DM
- Breast density B,
C or D (according to ACR BI-RADS)
- Median age 52 y/old (30 to 80 years old)
Tests were performed with medical prescription in all cases.
After signing an informed consent,
each patient underwent cranio-caudal and medio-lateral-oblique bilateral views,
in both FFDM and DBT.
The images were acquired during the same compression for each view with an narrow angle tomosynthesis ( Hologic Selenia Dimensions System / Bedford,
Mass.)
All US exams were hand-held physician performed,
with a high frequency linear transducer,
from 8 MHz to 14 MHz. The scanning time was 15 minutes.
Most of the ultrasound examinations were incident (repeat exams).
DBT screening exams were prevalent in the 1st year and mostly incident (repeat exams) from 2nd to 4th year.
We compared malignancy reported only by DBT,
only by BUS and by DBT plus BUS.
Accuracies and differences were analyzed.
