In this Sunday poster presentation, Dr. Michael Michell and colleagues will share data from a study they conducted to compare reader performance between single-view FFDM and single-view DBT.
The study included 154 cases, consisting of normal, benign, and malignant lesions. The images came from a database of recalled women who had bilateral FFDM and DBT in the mediolateral-oblique (MLO) and craniocaudal (CC) views. Thirteen readers read the series of 154 cases twice, one month apart.
For the CC view, Michell's group found the overall area under the receiver operator characteristics curve (AUC) to be 0.78 for FFDM and 0.82 for DBT -- for a borderline statistically significant difference (p-value = 0.05) between the two modalities. As for the MLO view, however, the overall AUC was 0.83 for FFDM and 0.87 for DBT, which was not statistically significantly different (p-value = 0.129).
