【摘要】：目的探讨TI-RADS分级结合弹性成像在甲状腺良恶性结节鉴别诊断的价值及不同医师间的一致性。方法 154个甲状腺结节行常规超声检查,依据TI-RADS分级标准判断良恶性;3级不确定者再行弹性成像检查,比较两名医师诊断的一致性。结果 (1)常规超声诊断一致率为81.5%,Kappa值为0.799;3级不确定者联合弹性成像诊断后一致率98.6%,Kappa值为0.806。(2)两名医师按照TI-RADS分级以及3级不确定者结合弹性成像鉴别恶性的灵敏度、特异度、准确度、阳性及阴性预测值医师1分别为84.91%、88.12%、87.01%、78.95%、91.75%;医师2为:84.91%、90.1%、88.31%、81.82%、91.92%。结论两名医师应用TI-RADS分级标准诊断甲状腺结节良恶性的一致性良好,3级不确定者联合弹性成像提高了诊断的准确度。
[Abstract]:Objective to explore the value of TI-RADS grading combined with elastic imaging in differential diagnosis of benign and malignant thyroid nodules and the consistency among different physicians. Methods 154 thyroid nodules were examined by conventional ultrasonography. According to the criteria of TI-RADS classification, the patients with benign or malignant grade 3 uncertainty were further examined by elastic imaging. Results 1) the consistent rate of conventional ultrasound diagnosis was 81.5 and the Kappa value was 0.799 ~ (3). The consensus rate after diagnosis was 98.6% and 0.806.02) the two physicians were divided into two groups according to TI-RADS grade and grade 3 uncertainty. Sensitivity of combined Elastic Imaging in differentiating malignant tumors, Specificity, accuracy, The positive and negative predictive values of physician 1 were 84.91 and 87.01, respectively, and 78.9551 and 91.75, respectively, and that of physician 2 was 84.91 and 98.31, respectively. Conclusion the accuracy of diagnosis was improved by using TI-RADS classification criteria for benign and malignant thyroid nodules.
