Abstract: Measured the shear wave velocity (SWV) in this paper by virtual touch tissue quantification (VTQ), and then compared the value of SWV, X-ray and color Doppler ultrasound in the diagnosis of breast cancer. 85 patients with breast lesions with breast masses were selected as the research objects. All patients received X-ray, ordinary color Doppler ultrasound, VTQ and surgical pathological biopsy. Taking the pathological results as the gold standard, and the patients with breast cancer were set as the breast cancer group (52 cases), and the patients with benign breast masses were set as the benign group (33 cases). Compared the blood flow resistance index (RI), SWV value and blood flow display rate of the two groups, and analyzed the efficacy of different imaging methods in the diagnosis of breast cancer. The RI, SWV and blood flow display rates in the breast cancer group were higher than those in the benign group (P<0.05). The imaging diagnosis results showed that the sensitivity and specificity of X-ray in the diagnosis of breast cancer were 32.69% and 45.45%, respectively. The sensitivity and specificity of ordinary color Doppler ultrasound in the diagnosis of breast cancer were 69.23% and 69.70%, respectively. The sensitivity and specificity of SWV in the diagnosis of breast cancer were 82.69% and 75.76%, respectively. The AUC of breast cancer diagnosed by SWV, conventional color ultrasound and X-ray were 0.801, 0.687 and 0.453, respectively. Compared with X-ray, common color ultrasound and other imaging methods, the SWV has the highest efficiency in diagnosing breast cancer, and SWV value can evaluate the hardness of lesions, making up for the deficiency of common ultrasound.
