The aim of this study was to investigate the diagnostic value of the Virtual Touch™ tissue quantification (VTQ) and elastosonography technologies in benign and malignant breast tumors. Routine preoperative ultrasound, elastosonography and VTQ examinations were performed on 86 patients with breast lesions. The elastosonography score and VTQ speed grouping of each lesion were measured and compared with the pathological findings. The difference in the elastosonography score between the benign and malignant breast tumors was statistically significant (P<0.05). The detection rate for an elastosonography score of 1-3 points in benign tumors was 68.09% and that for an elastosonography score of 4-5 points in malignant tumors was 82.05%. The difference in VTQ speed values between the benign and malignant tumors was also statistically significant (P<0.05). In addition, the diagnostic accuracy of conventional ultrasound, elastosonography, VTQ technology and the combined methods showed statistically significant differences (P<0.05). The use of the three technologies in combination significantly improved the diagnostic accuracy to 91.86%. In conclusion, the combination of conventional ultrasound, elastosonography and VTQ technology can significantly improve accuracy in the diagnosis of breast cancer.
本研究旨在探讨虚拟触诊组织定量（VTQ）和弹性超声技术在乳腺良恶性肿瘤中的诊断价值。对86例乳腺病变患者进行术前常规超声、弹性超声及VTQ检查。测量各病变的弹性超声评分及VTQ速度分组，并与病理结果进行比较。乳腺良恶性肿瘤的弹性超声评分差异有统计学意义（P<0.05）。良性肿瘤弹性超声评分为1 - 3分的检出率为68.09%，恶性肿瘤弹性超声评分为4 - 5分的检出率为82.05%。良恶性肿瘤的VTQ速度值差异也有统计学意义（P<0.05）。此外，常规超声、弹性超声、VTQ技术及联合方法的诊断准确性差异有统计学意义（P<0.05）。三种技术联合使用可将诊断准确性显著提高至91.86%。综上所述，常规超声、弹性超声及VTQ技术联合应用可显著提高乳腺癌的诊断准确性。
