The breast cancer diagnosis accuracy of the digital breast tomosynthesis technique

Abstract

Objective: To explore the Digital breast tomosynthesis technique (DBT) in breast cancer diagnosis accuracy. Methods: Choose 263 cases of patients with breast lesions, using DBT combined FFDM (Full field digital mammography) independent FFDM, evaluate the diagnostic accuracy of breast cancer. Results: The ROC curve area (AUC) of two kinds of breast cancer diagnosis methods (DBT combined FFDM and independent FFDM) were 0.954±0.014 and 0.907±0.019, with significant difference (P=0.000 3). In premenopausal patients and breast density ACR3-4 cases, DBT combined FFDM diagnosis accuracy is higher than FFDM alone group, with significant difference (P<0.05). Conclusion: DBT combined FFDM compared with independent FFDM, in a certain extent, improves the accuracy of the diagnosis of breast cancer.
