Abstract：Objective To explore the dose difference and clinical application value of 3D digital breast tomosynthesis (DBT) and fullfield digital mammography (FFDM) in the diagnosis of dense breast. Methods A total of 134 cases of clinically confirmed breast
patients were analyzed retrospectively. All patients completed FFDM and DBT imaging. The breasts were compressed according
to the operating specifications using the cranoocaudal view and the mediolateral oblique view, and photographed under the same
compression state. FFDM and DBT images were diagnosed independently, and the difference of radiation dose between them and
the ability of screening intraglandular lesions were compared. Results The sensitivity of DBT+V-preview was 88.57% (31/35),
specificity 80.81% (80/99)，and accuracy 82.83% (111/134); The sensitivity of FFDM was 57.14% (20/35), specificity 57.14%
(20/35), and accuracy 58.95% (79/134). In terms of the accuracy of BI-RADS classification and measurement of tumor size, DBT
was better than FFDM and the difference was statistically significant (χ2
=10.647, 8.741, 18.518; P<0.001). DBT could reduce tissue
overlap in dense glands, and the radiation dose of patients was equivalent. Conclusion DBT can be selected preferentially in the
screening of dense breast disease.
