- W2362189969 abstract "Objective To investigate the diagnostic accuracy of breast tumors by the virtual touch tissue quantification technique combined with ultrasound elasticity imaging.Methods 107 cases of breast tumors were enrolled in this study,the virtual touch tissue quantification technique and ultrasound elasticity imaging technique were performed at preoperative.The shear wave velocity(SWV)was measured by the VTQ in tumor center,and the grade of breast tumor hardness was valued by elasticity imaging technique.Using postoperative pathological results as the golden standard,the diagnostic accuracy of breast tumors by the virtual touch tissue quantification and ultrasound elasticity imaging were calculated.Results There was statistically significant in differential diagnosis of benign and malignant breast tumors by ultrasound elasticity imaging(P0.05),and the ROC curve showed that with the hardness grade 4as the critical value,the sensitivity was 92% and the specificity was 91% to diagnosis the benign and malignant breast tumor.There was statistically significant in differential diagnosis of benign and malignant breast tumors by VTQ(P0.05),and the ROC curve showed that with the SWV 3.91m/s as the critical value,the sensitivity was 85%and the specificity was 97%.There was statistically significant in differential diagnosis of benign and malignant breast tumor by VTQ combined with ultrasound elasticity imaging(P 0.05),the sensitivity was 93%,and the specificity was 95%.Conclusion The diagnostic accuracy of breast tumors can be improved by the virtual touch tissue quantification combined with elasticity imaging." @default.
