Abstract:Objective: To investigate the application value of virtual touch tissue quantification(VTQ) in the diagnosis of small solid breast nodules. Methods: The conventional ultrasonography(CUS) and VTQ were performed on 84 small solid breast nodules(diameter≤1 cm) of 76 patients. VTQ values were obtained and analyzed. Based on VTQ values of the small solid nodules, the hardness of the lesions were evaluated. With the pathological diagnosis as the gold standard, sensitivity and specificity of CUS and VTQ were compared. VTQ values of the ROC curve in the diagnosis of breast malignant nodules were sketched so as to explore the optimal cut-off point of VTQ values in the diagnosis of small malignant nodules. Result: CUS in the diagnosis of small solid nodules, the sensitivity and specificity were 77.3%, 80.0%. By the ROC curve test, the VTQ value of 2.89 m/s in the diagnosis of breast malignant nodules was designated as the cut-off point, with the sensitivity of 86.4%, specificity of 92.5%. Conclusion: VTQ technique can provide the hardness information of breast lesions, which has higher application value in the differential diagnosis of small solid breast nodules than CUS.
