A total of 54 lesions were detected (14 of them being invasive).
Considering the five BIRADS score system (B1,B2,B3,B4,B5),
the distribution at FFDM was (10,3,9,20,12),
while that of DBT was (4,4,15,14,17).
The BIRADS distribution of DBT was significantly shifted towards more clinically relevant scores respect the BIRADS of FFDM (p=0.048),
corresponding to a poor between-technique agreement (Cohen k=0.351).
Sensitivity of FFDM was 29/29 (100%; CI 88-100%),
that of DBT was 28/29 (97%; 82-100%).
In one patient DBT showed a bilateral tumor with only one lesion detected at FFDM; similarly,
in another case,
DBT showed a multifocal lesion with a focal lesion detected at FFDM.
