Comparison of digital breast tomosynthesis and full-field digital mammography imaging in the diagnosis of be-nign and malignant breast lesions of ACR-C class
Objective To compare the actual application effects of full digital mammography(FFDM)and digital breast tomosynthesis(DBT)in the diagnosis of benign and malignant breast lesions of ACR-C class.Methods Totally 108 patients with breast lesions were selected.They were all received FFDM and DBT examination.The diagnostic efficacy of FFDM and DBT was evaluated refer to the pathological results according to the Breast Imaging Reporting and Data System(BI-RADS)score.Results The sensitivity,specificity,positive predictive value,negative predictive value,and accuracy of DBT in the diagnosis of benign and malignant breast lesions was 84.61%,95.12%,84.61%,95.12%,and 92.59%,which were better than those of FFDM(53.85%,90.24%,63.64%,86.05%,81.48%).The sensitivity between the two methods showed a statistically significant difference(Z=-8.55,P<0.05),while there was no significant difference in specificity(Z=-0.71,P>0.05).DBT was significantly better than FFDM in detecting breast masses and displaying clear and obscured signs,with statistically significant differences(χ2=4.38,25.34,10.46,P<0.05).Conclusion The diagnos-tic efficacy of DBT for benign and malignant breast lesions of ACR-C class is significantly improved compared to FFDM.
