Abstract

Objective To investigate the diagnostic value of full-field digital mammography (FFDM) combined with three-dimentional digital breast tomosynthesis (3D-DBT) in the lesions of dense breast mass. Methods A total of 121 patients with breast mass (135 lesions) in Shanxi Provincial People's Hospital from January 2018 to May 2018 were retrospectively analyzed. The differences of FFDM combined with 3D-DBT technique and FFDM alone in the diagnosis of dense breast mass lesions were compared and analyzed by using American Radiological Society's Breast Imaging Reporting and Data System (BI-RADS) grading diagnosis, and then the pathological results were compared. Results The sensitivity, accuracy rate and specificity of FFDM combined with 3D-DBT in the diagnosis of breast cancer among 135 lesions was 97.3% (36/37), 80.0% (108/135) and 73.5% (72/98), respectively. The sensitivity, accuracy rate and specificity of FFDM in the diagnosis of breast cancer was 86.5% (32/37), 70.4% (95/135) and 64.3% (63/98), respectively. Area under the receiver operating characteristic curve of FFDM combined with 3D-DBT was higher than that of FFDM alone (0.854 vs. 0.754). Compared with FFDM, mass diameter measured by 3D-DBT was close to the pathological results. The detection rates of mass, burr features and suspected malignant aggregation calcification by using FFDM combined with 3D-DBT were superior than those by using FFDM [100.0% (72/72) vs. 81.9% (59/72), 52.8% (19/36) vs. 41.7% (15/36), 75.0% (27/36) vs. 66.7% (24/36), respectively]. Conclusions For the focal mass of compact glands, compared with FFDM alone, the accuracy rate of the mass measurement, the detection rate of the suspected mass, the malignant mass burr, and the micro-calcification of aggregation treated by FFDM combined with 3D-DBT have been increased in a varying degree.
