Abstract：Objective: To investigate the diagnosis of breast cancer and the calcification of breast calcification in full-screen digital mammography (FFDM) and digital breast tomography (DBT). Methods: A total of 156 patients with dense breast adenocarcinoma who came to our hospital from March 2017 to March 2018 were enrolled. All patients were diagnosed by DBT and FFDM, and the breast gland density classification, lesion morphology, size, quantity and boundary were analyzed and recorded. The pathological diagnosis was used as the gold standard to evaluate the compactness of the two examination methods. The detection rate and focus characteristics of breast cancer in dense breast by two methods were evaluated. Results: A total of 157 lesions were detected in 156 patients, all of which were breast cancer. One of them was bilateral breast cancer. Using pathological examination as a standard, in 156 patients, 51 patients (32.69%) had breast cancer glandular tissue with high uniformity and dense breast cancer, and 105 patients (67.31%) had uneven and dense breast cancer. The diagnostic accuracy of DBT for dense breast breast masses and calcifications in breasts (78.34%, 54.14%) was significantly higher than that of FFDM (56.69%, 35.67%) (P<0.05). Moreover, the total diagnostic accuracy of DBT for dense mammary gland (82.80%) was significantly higher than that of FFDM (67.53%) (P<0.05). DBT showed a better overall effect on the boundary of dense breast lesions than FFDM (Z=-9.196, P<0.05). DBT showed significantly better burr signs and vascular penetration signs in dense breast cancer than FFDM (P<0.05). There was no significant difference in the total detection rate of breast cancer calcification in dense breasts between the two methods (χ2=2.136, P>0.05). Conclusion: Compared with FFDM, DBT is more conducive to the characteristics of lesions in patients with calcification, and is more suitable for the diagnosis and calcification of breast cancer in dense breast.
