The aim of this study was to evaluate the technical characteristics and diagnostic efficiency of Digital Breast Tomosynthesis (DBT) compared to conventional MRI approach and full-field digital mammography (FFDM) in screening breast cancer (BC) patients. Briefly, 253 female patients who underwent Digital Mammary Gland 3D Tomosynthesis, MR scan and FFDM were enrolled in this study. Briefly, the DBT, FFDM and MRI showed a sensitivity of 90.9%, 85.6% and 94.1%; specificity of 89.7%, 80.7% and 83.3%; and coincidence rate of 89.3%, 83.4% and 89.7%, respectively, and the difference was statistically significant (p＜0.001).
