摘　　要：目的探讨定量声触诊组织成像(VTIQ)技术的剪切波数值在甲状腺乳头状癌淋巴结转移性癌检出中的效能。方法回顾性分析已明确有甲状腺乳头状癌病史的经淋巴结穿刺活检或手术有病理诊断的105个颈部淋巴结的剪切波速度(SWV)。结果 105个淋巴结有恶性74个和良性31个。良性组SWV最小值、最大值、中位数及平均值与恶性组的差异均有统计学意义(t=6.83、6.97、7.76、7.69,P均<0.001)。依据ROC曲线分析,SWV测值中效能以平均值为最佳,界值是2.695m/s。得出SWV平均值灵敏度、特异度和Youden数值分别是89.20%、77.40%、0.666。结论 VTIQ技术采用SWV平均值于甲状腺乳头状癌淋巴结转移性癌诊断中具有一定的应用价值。Objective To investigate the application study of the virtual touch tissue image quantification （VTIQ） technique in the differential diagnosis of metastatic carcinoma in thyroid papillary carcinoma with lymph node. Methods The imaging data of 105 lymph nodes proven by biopsy pathology or operating on VTIQ were retrospective- ly analyzed. Results According to the pathology results, there were 74 malignant lymph nodes and 31 benign lymph nodes. There were significant differences between malignant and benign lymph nodes in SWVmax, SWVmin, SWV- median, and SWVmean on VTIQ （t = 6.83, 6.97, 7.76, 7.69, P〈0.01）. Based on ROC curve analysis, the SWVmean value in the lymph nodes was the best value in comparison with other SWV values. The cut-off value of VTIQ mean was 2. 695 m/s. And, the sensitivity, specificity and Youden index for VTIQ were 89.20%, 77.40%, 0. 666, respectively. Conclusions The study proved that VTIQ technique has certain application value in metastatic carcinoma in thyroid papillary carcinoma with lymph node and the SWVmean is the best parameter for differential diag- nosis.
