Abstract:Objective To investigate the clinical value of virtual touch image quantification in breast solid lesions. Methods A total of 238 patients with breast lesions (254 solid lesions) were examined by conventional two-dimensional ultrasound and VTIQ. All lesions were obtained by needle biopsy or surgery. The differences of various elastic indexes in the benign and malignant breast lesions group were analyzed, including VTIQ imaging velocity model diagram and shear wave velocity value Vmax, Vmin and Vmean of breast lesions, and the ROC curves of the three subjects were drawn to determine the diagnostic threshold value and evaluate the diagnostic efficacy of VTIQ technology in the diagnosis of benign and malignant breast lesions. Results In VTIQ imaging, the color-coded graph of the velocity pattern displayed by solid lesions of the breast can be divided into five types: homogeneous, heterogeneous, disorganized, diffuse, and hard ring. Homogenous and nonhomogenous lesions are more common in benign breast lesions, while disordered, diffuse and hard ring lesions are more common in malignant breast lesions. VTIQ imaging shear wave velocity indexes Vmax, Vmin and Vmean have high diagnostic efficiency in the diagnosis of benign and malignant breast lesions. After comprehensive judgment, Vmean can be used as the best indicator for the diagnosis of benign and malignant breast lesions, and the diagnostic threshold value is 4.84m/s. Conclusions The application of VTIQ technology in the diagnosis of benign and malignant breast solid lesions has a high diagnostic efficiency. Vmean can be used as a reliable evaluation index for the diagnosis of benign and malignant breast lesions, and Vmax and Vmin can be used as auxiliary evaluation indexes for special breast lesions.
