目的：探讨甲状腺超声影像和数据报告系统(TI-RADS)分级在诊断不同年龄甲状腺结节中的应用价值。方法选择527例甲状腺结节患者，按年龄段分为4组（26～35岁组、36～45岁组、46～55岁组、56～65岁组），采用TI-RADS对4个年龄组的甲状腺结节患者进行分级，并与病理结果对比分析。结果 TI-RADS分级对低年龄组（26～35岁组和36～45岁组）结节患者的诊断阳性预测值、阴性预测值和正确率均高于90%；对46～55岁组的阳性预测值为81.5%，阴性预测值为87.5%，正确率为81.9%；对56～65岁组的阳性预测值为76.6%，阴性预测值为88.8%，正确率为77.9%。TI-RADS系统对56～65岁甲状腺结节患者的诊断率低于其他年龄分组。结论 TI-RADS分级方法受年龄因素的影响，对高年龄组的诊断率低于低年龄组。

Objective To explore the applied value of thyroid imaging reporting and data system (TI-RADS) strati?fication in diagnosing thyroid nodules in patients with different ages.Methods A total of 527 patients with thyroid nod?ules (aged 26-65) were divided into four groups:aged 26-35 group, aged 36-45 group, aged 46-55 group and aged 56-65 group. TI-RADS was used to evaluate patients in four groups. The results of TI-RADS were compared with the pathologic di?agnostic analysis. Results For the low aged groups (aged 26-35 group and aged 36-45 group), the positive predictive val?ue, the negative predictive value and accuracy rate were more than 90%. With regard to the patients aged 46-55, the positive and negative predictive values and accuracy rate were 81.5%, 87.5%, and 81.9%, respectively. The positive and negative predictive values, accuracy rate were 76.6%,88.8%and 77.9%for patients aged 56-65 group. The diagnostic rate of TI-RADS in patients with thyroid lesions was lower in aged 56-65 group than that of other groups. Conclusion TI-RADS method is affected by age. The diagnostic rate is lower in the high age group than that of the low age group.
