Objective:The purpose of this study was to evaluate the impact of computer-aided detection(CAD)on the performance of mammogram reader in interpreting pure calcification lesion.Methods:A retrospective review was performed in 46 patients with pure calcification lesion detected by full-field digital mammography(FFDM),and every lesion was given a BI-RADS score before and after CAD analysis.The BI-RADS scores of lesion before and after CAD analysis were compared.The overall diagnostic accuracy and sensitivity for detecting malignant lesion were compared between analysis before and after CAD.Results:There was significant difference in the BI-RADS scores(χ2=78.04,P0.001)and in the diagnostic accuracy of lesions(P=0.001)between analysis before and after CAD.There was no significant difference in the sensitivity of detecting malignant lesion between analysis before and after CAD(P=0.059).Conclusion:Our results indicate that systematic application of CAD with FFDM in a clinical patient population should be effective in assisting radiologist to improve the mammogram interpretation accuracy and the sensitivity of detecting breast cancer.
