To evaluate the perceived diagnostic value of reconstructed synthetic two-dimensional (S2D) images when added to digital breast tomosynthesis (DBT).
Methods and materials
100 DBT examinations were reviewed in this reading study.
11showed proven breast malignancies.
Two independent breast radiologists (20 and 1.5 years of experience) assessed the cases after patient management was completed. To simulate screening and diagnostic situations,
the readers were blinded on clinical history for 50 patients and un-blinded for the other 50 (6 malignant). Readings were performed with DBT alone,
then with added S2D images. Perceived added diagnostic value of S2D images...
The addition of synthetic 2D images to DBT was scored beneficial overall in 40 cases (40%) and 53 cases (53%) by Reader 1 and Reader 2,
respectively. Across all readers and subjects,
the addition of S2D views was perceived beneficial,
with no impact,
or negatively versus DBT alone in 41%,
and 4% of cases,
respectively (eaxmples in Fig.
1). The addition of S2D images was rated particularly useful in the assessment of 79% of distortions and asymmetries (41 cases out of 52). The Wilcoxon...
Synthetic 2D images may bring additional diagnostic value to DBT volumetric image sets alone,
in particular for assessing distortions and asymmetries.
