Abstract：Objective To investigate the clinical value of three-dimensional full volume automatic breast scanning(ABVS),conventional ultrasound(US)and ultrasound elastography(UE)in the diagnosis of breast mass.Methods 140 patients with breast mass were selected.Pathological examination was used as the gold standard.68 cases of malignant mass and 72 cases of be-nign mass were confirmed by gold standard.ABVS,US and UE were examined before pathological diagnosis.The characteristics of ABVS,US and UE scores were observed.The positive and negative predictive values of ABVS,US,UE and the combined di-agnosis of malignant breast mass were calculated by using four-cell table method.Receiver operating characteristic(ROC)curves were drawn to analyze the AUC,sensitivity and specificity of ABVS,US,UE and the combined diagnosis of malignant breast masses.Results The irregular shape,unclear boundary,calcification,attenuation of rear echo,aspect ratio≥1,gradeⅡ-Ⅲ blood flow signal in malignant mass group were higher than those in benign mass group(P<0.05).The aggregation signs,insect erosion,microcalcification and UE score of malignant mass were higher than those of benign mass(P<0.05).ABVS was examined in 140 patients with breast mass,and the positive and negative predictive values were 81.54%and 80.00%,respec-tively.By US examination,the positive and negative predictive values were 63.49%and 63.64%,respectively.UE test showed that the positive and negative predictive values were 83.33%and 82.43%,respectively.The positive and negative predictive val-ues of three combined tests were 92.54%and 91.78%,respectively.The diagnostic rate of the three combined diagnoses was higher than that of ABVS and USUE(χ2=7.795,33.146,5.518,P<0.05).ROC curve analysis showed that the AUC values of ABVS,US,UE and combined diagnosis of malignant breast masses were 0.801,0.618,0.827,and 0.926(P<0.05).Conclusion ABVS combined with US and UE has high efficiency in the differential diagnosis of benign and malignant breast masses,which is beneficial to improve the accuracy.
