Methods and Materials
Forty-six patients (aged 59±11 years) with at least one breast lesion detected at screening (n=10) or diagnostic (n=36) FFDM underwent mediolateral oblique DBT (Giotto Tomo,
An independent dedicated breast radiologist reviewed all examinations (time interval at least 30 days).
For each lesion,
a BIRADS score was assigned both at FFDM and DBT.
The BIRADS score distributions of FFDM and DBT were compared using the Wilcoxon test and the Cohen k coefficient.
Considering BIRADS 1 and 2 as negative and BIRADS 4 and 5 as positive,
sensitivity and 95% confidence intervals (CI) were calculated using histology of biopsied lesions as reference standard.
