- Abstract:
- Abstract: Objective To compare the efficacy of digital breast tomosynthesis (DBT), color Doppler ultrasound, and DBT+color Doppler ultrasound for the diagnosis of breast lesions. Methods Among the 1 065 patients with breast lesions enrolled in this study, 333 cases had complete pathological examination data. Using breast imaging reporting and data system (BI-RADS) classification as the criterion, the distribution differences among DBT, ultrasound, and DBT+ultrasound in diagnosis of breast lesions were analyzed. Based on the pathological results of 333 cases, the diagnostic efficacies of 3 diagnostic models were compared. Results There were significant differences in BI-RADS distribution between DBT and ultrasound (P=0.001), and no significant differences were found between DBT and DBT+ultrasound or between ultrasound and DBT+ultrasound (P=0.258, 0.394). All 3 diagnostic models distinctly discriminated the malignant and benign breast lesions (all P<0.001). The analysis with multi-group independent-sample Kruskal-Wallis test showed that there were differences among 3 diagnostic models ([χ2]=14.982, P=0.001). DBT was superior to ultrasound in the specificity, misdiagnosis rate, accuracy and positive predictive value. Ultrasound was better than DBT in displaying the cystic lesions, and the sensitivity of ultrasound in determining benign masses was higher than that of DBT. The specificity, misdiagnosis rate and positive predictive value of DBT+ultrasound were 99.5%, 0.5% and 99%, respectively. The combined use of DBT and ultrasound was better than using DBT or ultrasound alone in the diagnosis of breast diseases. Conclusion Compared with using DBT or ultrasound alone, the combination of DBT and ultrasound can improve the diagnostic efficacy of breast lesions.
