Abstract:
Objective To evaluate the value of virtual touch tissue imaging quantification (VTIQ),which was combined with ultrasound Breast Imaging Reporting and Data System (BI-RADS),for differentiating benign from malignant breast lesions.Methods Totally 190 patients with 214 breast lesions were enrolled in this study.All lesions were classified according to the BI-RADS for sonography.The maximum,minimum and mean shear wave velocity (SWV) values on VTIQ in the lesions were obtained.The SWV between benign and malignant lesions were analyzed.Receiver operating characteristic(ROC) curves were plotted to determine the cut off value of VTIQ for differential diagnosis of breast lesions. Results Pathology confirmed 166 benign lesions and 48 malignant lesions.The SWVmax,SWVmin,SWVmean of malignant lesions were significantly higher than those of benign lesions (all P<0.001).The SWVmean 3.67 m/s as the best value in the diagnosis of benign and malignant lesions.The sensitivity,specificity,positive predictive value and negative predictive value of the combination of the SWVmean and BI-RADS classification standard in the diagnosis of benign and malignant breast lesions were 77.6%,97.5%,92.7%,91.3%,respectively.Conclusions The combination of VTIQ and ultrasonic BI-RADS can improve the ability of differential diagnosis of benign and malignant breast lesions.
