【摘要】 目的探讨甲状腺超声影像和数据报告系统(TI-RADS)分类在诊断甲状腺结节中的应用价值。方法对263例甲状腺结节患者的524个甲状腺结节进行TI-RADS分类,并与病理结果对照做诊断性分析。结果甲状腺良性结节多见于TI-RADS 2、3、4A类结节,恶性结节则多见于TI-RADS 4B、5、6类结节。若以TI-RADS2、3、4A类甲状腺结节为良性结节,以TI-RADS 4B、5、6类为恶性结节,进行统计学分析,两者诊断甲状腺结节良、恶性的差异具有统计学意义(χ~2=298.49,P<0.01),其诊断甲状腺结节的准确性、灵敏性和特异性分别为93.3%(489/524),83.7%(67/80),95.0%(422/444)。超声TI-RADS分类诊断的ROC曲线下面积为0.889。结论 TI-RADS分类方法可较好地应用于诊断甲状腺结节。更多还原

【Abstract】 Objective To explore the applicational value of thyroid imaging reporting and data system(TI-RADS) ultrasonographic stratification in diagnosing thyroid nodules.Methods A total of 263 patients with 524 thyroid nodules were evaluated by using TI-RADS ultrasonographic stratification,and the results were compared with pathologic diagnostic analysis.Results Benign nodules almost belong to TI-RADS 2,3 and TI-RADS 4A,malignant nodules are more common in TI-RADS 4B,5 and 6 category nodules.If thyroid nodules of TTRADS 2,3 and 4A category were prediction of benign nodules,and TI-RADS 4,5 and 6 category were prediction of malignant nodules,they were statistically significant differences(χ~2=298.49,P<0.01),the accuracy,sensitivity and specificity of TTRADS in diagnosis of benign and malignant thyroid lesions were 93.3%(489/524),83.7%(67/80),95.0%(422/444).Conclusions TTRADS can be well used in diagnosis of thyroid nodules.The area under ROC curve was 0.889.更多还原
