| 【】目的 探讨TI –ＲADS 分级、弹性评分、造影增强模式联合诊断在鉴别甲状腺结节良恶性中的应用价值。方法 经病理证实135病人的162个结节分别行 TI － ＲADS 分级、弹性评分、造影增强模式分析,判断结节的良恶性,评估三种方法诊断效能及联合诊断后的敏感性、特异性、准确性,并进行评分分析,与术后病理结果对照,利用受试者操作特征曲线(ROC)评估其诊断价值以确定甲状腺结节良恶性的分数临界值。结果,单一行高频超声TI-RADS分级检测灵敏度为69.0%(37/54),特异度为64.8%(70/108),准确率66.1%。单一弹性成像评分法其敏感性为81.5%(44/54),特异性82.4%(89/108),准确率82.1%,超声造影诊断其敏感性为77.8%(42/54),特异性为86.7%(93/108),准确性为83.3%。; 三者联合诊断敏感性、特异性、准确性分别为85.2% ( 46/54) ,95.3%( 103 /108),91.2 %。联合后分别与单独 TI － ＲADS 分级、弹性评分及CEUS 比较敏感性、特异性、准确性差异有统计学意义 P 均 ＜0. 05,与术后病理结果对照,根据ROC 曲线判断甲状腺结节良恶性的诊断效能和临界分数。结论 TI-ＲADS 分级、弹性成像技术和超声造影联合诊断,提高了超声对甲状腺结节的诊断效率,当三者评分相加大于6时,可判断为恶性。 |

| Abstract: |
| 【】Objective To investigate the TI -RADS grade, elasticity score, contrast-enhanced mode for diagnosing malignant application value in differentiating benign thyroid nodules. Methods Pathologically confirmed 162 nodules 135 patients underwent TI - RADS classification, elasticity score, contrast-enhanced pattern analysis, judgment benign and malignant nodules, evaluate the diagnostic efficacy of three methods of diagnosis and sensitivity of joint, specificity, accuracy, and score analysis to determine the benign and malignant thyroid nodules score threshold. Results Single routine ultrasound inspection sensitivity of 69.0% (37/54), specificity was 90.7% (98/108), the accuracy rate was 83.3%. Single elastography score sensitivity of 81.5% (44/54), specificity 82.4% (89/108), 82.1% accuracy rate, CEUS diagnosis sensitivity 77.8% (42/54), specificity 86.7% (93/108), the accuracy was 83.3%. ; Three joint diagnostic sensitivity, specificity and accuracy of points respectively, 85.2% ( 46/54) ,95.3%( 103 /108),91.2 % . United were alone after TI - RADS classification, elasticity score and CEUS compare the sensitivity, specificity, accuracy difference was statistically significant, P <0.05, making the ROC curve, when the sum of the three scores greater than 6 can be. diagnosed as malignant. Conclusions The TI-RADS classification, elasticity imaging techniques and contrast-enhanced ultrasound combined diagnosis, improve the efficiency of ultrasound diagnosis of thyroid nodules, when the sum of the three scores greater than 6, it can be judged to be malignant. |
