Abstract:
Objective To evaluate the application value of virtual touch tissue quantification(VTQ) in the differential diagnosis of small breast lesions.Methods Fifty-six patients with sixty-nine small breast lesions whose largest diameter were less than or equal to 1 cm were evaluated with VTQ.The shear wave velocity (SWV) of the lesions and normal breast tissue were measured to analyze the diversity of different pathological types lesions of SWV and to find the optimal cut-off points using ROC curve to predict small breast cancer.Resuits The mean SWV(Vm) and the ratio (mean of lesions and normal tissue) of SWV (Vm1/Vm2) in benign group was (2.93 ± 1.32)m/s,1.79 ± 0.63,respectively,and that in malignant group was (5.65 ± 2.63) m/s,3.61 ± 1.35,respectively,there were statistically significant differences between benign group and malignant group (t test,P ＜0.05).The cut-off point of Vm was determined as 4.43 m/ s,the sensitivity,specificity and accuracy of diagnosing breast cancer were 80.5％,89.3％,92.8％,respectively.The cut-off point of Vm1/Vm2 was determined as 2.37,the sensitivity,specificity and accuracy of diagnosing breast cancer were 76.9％,81.2％,89.9％,respectively.Conclusions VTQ technique can provide helpful information in the differential diagnosis of small breast lesions.
