【摘要】：目的比较声触诊定量技术(VTQ)与声触诊成像定量技术(VTIQ)在鉴别甲状腺结节性质中的应用价值。方法选择甲状腺结节患者100例(118枚结节),经手术或结节穿刺病理证实良性结节41枚、恶性结节77枚。采用Siemens Acuson S3000型超声诊断仪分别于VTQ及VTIQ模式下测量剪切波速度(SWV);绘制VTQ与VTIQ对结节性质判断的受试者工作特性曲线,计算曲线下面积(AUC),计算两种方法对结节性质的判断效能。结果VTQ测量失败率为5%(6/118),良、恶性结节的SWV分别为(2.43±0.52)、(3.68±0.91)m/s,二者比较P0.01。VTIQ测量失败率为0,良、恶性结节的SWV分别为(2.34±0.85)、(3.81±1.07)m/s,二者比较P0.01。VTQ与VTIQ的AUC分别为0.621(95%CI:0.512~0.730)、0.723(95%CI:0.621~0.825)。VTIQ判断结节性质的敏感性、特异性、阳性预测值、阴性预测值及准确率均高于VTQ。VTQ与VTIQ判断直径≤1 cm结节性质的敏感性、特异性、阳性预测值、阴性预测值及准确率均高于直径1 cm结节,且VTIQ均高于VTQ。结论 VTQ与VTIQ对于直径≤1 cm甲状腺结节性质的判断效能均较高,但VTIQ的总体判断效能高于VTQ。
[Abstract]:Objective to compare the value of acoustic palpation quantitative technique (VTQ) and acoustic palpation imaging quantitative technique (VTIQ) in distinguishing thyroid nodule. Methods one hundred patients with thyroid nodules were selected, including 41 benign nodules and 77 malignant nodules confirmed by operation or nodule puncture pathology. The shear wave velocities were measured by Siemens Acuson S3000 ultrasonic diagnostic instrument in VTQ and VTIQ mode respectively, and the operating characteristic curves of VTQ and VTIQ to judge the nodular properties were plotted, the area under the curve was calculated, and the effectiveness of two methods to judge the nodular properties was calculated. Results the failure rate of VTQ was 5 / 6 / 118, the SWV of benign and malignant nodules was 2. 43 卤0. 52 卤0. 91 m / s, the SWV of benign and malignant nodules was 0, and the SWV of benign and malignant nodules was 2. 34 卤0. 85 卤1. 07 m / s, respectively. The AUC of P0.01.VTQ and VTIQ were 0. 621%, 0. 75%, 0. 730% and 0. 723 95% respectively. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy rate of positive predictive value, negative predictive value and accuracy were higher than those of VTQ.VTQ and VTIQ in judging diameter 鈮，
