| 目的 探讨声触诊组织成像量化技术（VTIQ）在乳腺实性病灶中的临床应用价值。方法 对238例患有乳腺肿块的患者（乳腺实性病灶254个）进行常规二维超声检查及声触诊组织量化技术（VTIQ）检查，所有病灶都通过穿刺活检或手术得到病理结果。分析乳腺良性病灶组、恶性病灶组各弹性指标的差异，包括VTIQ成像速度模式图及乳腺病灶的剪切波速度值Vmax、Vmin、Vmean，并绘制三者受试者工作特征（ROC）曲线，确定诊断界点值，评估VTIQ技术诊断乳腺良恶性病灶的诊断效能。结果 VTIQ成像中，乳腺实性病灶所显示的速度模式彩色编码图可分为五种类型：均匀型、欠均匀型、杂乱型、扩散型、硬环型。均匀型、欠均匀型多见于乳腺良性病灶，杂乱型、扩散型、硬环型多见于乳腺恶性病灶。VTIQ成像剪切波速度指标Vmax、Vmin、Vmean在诊断乳腺良恶性病灶中均具有较高的诊断效能，经综合判断，Vmean可作为诊断乳腺良恶性病灶的最佳指标，诊断界点值为4.84m/s。结论 VTIQ技术应用于乳腺实性病灶良恶性诊断时具有较高的诊断效能，Vmean可作为乳腺良恶性病灶诊断的可靠评价指标，Vmax、Vmin可作为特殊乳腺病灶的辅助评价指标。 |

| 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. |
