| 摘 要：［目的］ 对比探讨甲状腺影像报告和数据系统（thyroid imaging reporting and data system，TI-RADS分类）与常规超声在诊断甲状腺结节良恶性中的诊断效能。［方法］ 对253例患者共266个甲状腺结节行常规超声检查，观察病灶的大小、数量、形态、边界、内部回声及后场情况特征并评估良恶性，同时运用TI-RADS分类方法对上述结节进行分类，以TI-RADS分类2、3、4a类为良性结节，4b 、4c、5类为恶性结节；结果均以病理为参照标准进行分析。［结果］ 常规超声诊断甲状腺结节良恶性：灵敏度70.7%、特异度87.5%、准确率85.0%、阳性预测值50.8%、阴性预测值94.3%；TI-RADS分类诊断甲状腺结节良恶性：灵敏度90.2%、特异度81.3%、准确率82.7%、阳性预测值46.8%、阴性预测值97.9%。TI-RADS分类较常规超声具有较高敏感性（P=0.026）。［结论］ TI-RADS分类与常规超声在甲状腺结节定性诊断中均具有较高的诊断价值；TI-RADS分类系统是一个标准化工具，使甲状腺结节超声定性诊断规范化，利于临床对患者分类管理。 |

| Abstract：［Objective］ To assess the value of thyroid imaging reporting and data system (TI-RADS) and conventional ultrasonography in differential diagnosis of benign and malignant thyroid nodules. ［Methods］ Two hundred and sixty-six thyroid nodules from 253 patients were examined by using conventional ultrasonography. The thyroid nodules were classified as benign or malignant based on the size，quantity，shape，boundary，internal echoes and back area features of lesions. Meanwhile，the thyroid nodules were also classified by using the TI-RADS. The diagnostic accuracy of two methods was assessed with pathological results as gold standard. ［Results］ The sensitivity，specificity，accuracy rate，positive predictive value and negative predictive value of conventional ultrasound in diagnosis of benign and malignant thyroid nodules were 70.7%，87.5%，85.0%，50.8% and 94.3% respectively；while those of TI-RADS were 90.2%，81.3%，82.7%，46.8% and 97.9% respectively. The sensitivity of TI-RADS was higher than that of conventional ultrasound(P=0.026). ［Conclusions］ Both TI-RADS and conventional ultrasonography have high value in differential diagnosis of thyroid nodules. TI-RADS classification system can be used as a standardized tool for management of patients with thyroid nodules with different classification. |
