| Abstract:Objective: To explore the value of conventional ultrasound combined with virtual touch tissue imaging quantification (VTIQ) in differential diagnosis of benign and malignant breast lesions. Methods: Sixty-two breast lesions from Xiamen Branch, Zhongshan Hospital, Fudan University in April 2019 to September 2019 were examined by conventional ultrasound and VTIQ technique. The echo, morphology, punctate calcification and perforator blood flow were observed by conventional ultrasound. The SWVmax and the SWVmean of transverse shear wave velocity (SWV) were measured by VTIQ technique. The cut-off values of SWVmax and SWVmean were calculated by ROC curve based on pathological results. Diagnostic efficacy of conventional ultrasound combined with VITQ was compared with conventional ultrasound for breast lesions diagnosis. Results: Among 62 cases, 41 cases were benign tumors and 21 cases were malignant tumors. The cut-off points of SWVmax and SWVmean of VTIQ were 5.4 m/s and 4.2 m/s, respectively. The sensitivity and specificity of SWVmax and SWVmean were 72.0%, 92.1% and 86.0%, 79.0%. The sensitivity, specificity, accuracy, positive and negative predictive values of conventional ultrasound and conventional ultrasound combined with VTIQ were 68%,74%,42%,72%,83% vs 77%, 97%, 74%, 86%, 92% with significant difference(P<0.05). Conclusions: Conventional ultrasound combined with VTIQ is helpful to improve the diagnostic ability of conventional ultrasound for breast lesions, which is worthy of further promotion. |
