Abstract:
Objective To analyze the clinical value of digital breast tomosynthesis (DBT) compared with digital mammography (DM) and ultrasound for diagnosing non-calcified masses in dense breasts.Methods Images taken with DBT,DM and ultrasound of 1144 patients with non-calcified masses in dense breasts were retrospectively analyzed using breast imaging reporting and data system (BI-RADS).Taking histopathologic results as golden standards,the detection rate and diagnostic accuracy,sensitivity,specificity,false negative and BI-RADS category were evaluated and compared statistically.Results The detection rate of DBT,DM and ultrasound for non-calcified massed in dense breasts was 86.62％ (991/1 144),77.80％ (890/1 144) and 99.65％ (1 140/1 144),respectively (P＜0.05),while the diagnostic accuracy was 83.92％ (960/1 144),75.00％ (858/1 144) and 94.67％ (1 083/1 144),respectively (P＜0.01).The sensitivity of DBT,DM and ultrasound was 89.39％ (312/349),79.93％ (231/289) and 92.70％ (432/466),the specificity was 81.51％ (648/795),73.33％ (627/855) and 96.02％ (651/678),while the false negative rate was 10.60％(37/349),20.07％ (58/289) and 7.30％ (34/466),respectively.No significant difference was found for benign lesions among three examination methods (P=0.75),while there was significant difference for malignant lesions among three examination methods (P＜0.01),and the differences of ultrasonography with DM and DBT,DBT and DM in the for BI-RADS category of malignant lesions were statistically significant (all P＜0.016 7).Conclusion For suspected masses in dense breasts,DBT shows significant advantage than DM,while DBT has the similar advantage compared with ultrasound for the detection and diagnosis of non-calcified masses in dense breasts.
