摘要:

目的：研究美国放射学会甲状腺影像报告和数据系统（ACR TI-RADS）对甲状腺结节风险的诊断价值，分析ACR TI-RADS分级对于不同大小结节（以结节大小1 cm为界）的诊断效能，以指导临床。方法：收集2018年1月至2019年1月于我院行甲状腺结节切除术患者122例，利用二维超声对其136个结节进行了ACR TI-RADS分级评分，与病理结果对照绘制ROC曲线下面积，并观察ACR TI-RADS分级的灵敏度及特异度分布，利用曲线下面积（AUC）比较超声ACR TI-RADS分级对甲状腺结节的诊断价值及对不同大小结节在诊断上的效果。结果：二维ACR TI-RADS分级评分得到的ROC曲线下面积为0.855 3（0.753 7， 0.914 1），最佳界值点为6.5。＞1 cm与≤1 cm甲状腺结节间ACR TI-RADS分级评分的AUC 95%CI 无交叉，因此对于＞1 cm与≤1 cm结节间的ACR TI-RADS分级评分的诊断效果差异有统计学意义。结论：ACR TI-RADS分级系统对于判断甲状腺结节风险有价值，诊断的灵敏度95.3%、特异度62.7%，分级为TR5级的结节恶性风险明显增加。ACR TI-RADS分级对于直径>1 cm的甲状腺结节的诊断效能优于直径≤1 cm的结节。

Abstract:

Objective: To study the diagnostic value of the American Radiological Society Thyroid Imaging Reporting and Data System (ACR TI-RADS) in assessing the risk of thyroid nodules, and to analyze the diagnostic efficacy of the ACR TI-RADS classification for nodules of different sizes(with a nodule size of 1cm) to guide clinical practice. Methods：122 cases of thyroid nodule resection in our hospital from January 2018 to January 2019 were collected. The 136 nodules were graded by ACR TI-RADS using two-dimensional ultrasound, and the area under ROC curve was drawn by compared with the pathological results. The sensitivity and specificity distribution of ACR TI-RADS grading were observed. The diagnostic value of ultrasonic ACR TI-RADS grading for thyroid nodules and the diagnostic effect on nodules of different size were compared by using the area under curve(AUC). Results：The area under the ROC curve obtained by the two-dimensional ACR TI-RADS classification score was 0.855 3(0.753 7, 0.914 1), and the best cut-off point was 6.5. There was no crossover between the thyroid nodule diameter >1 cm and the nodule diameter ≤1 cm by ACR TI-RADS grading score AUC 95% CI, so there was a statistically significant difference in the diagnostic effect of ACR TI-RADS grading score between >1 cm and ≤1 cm nodule. Conclusion： The ACR TI-RADS grading system is valuable for judging the risk of thyroid nodules. The diagnostic sensitivity is 95.3% and the specificity is 62.7%. The malignant risk of nodules classified as TR5 is significantly increased. The ACR TI-RADS classification for the diagnosis of thyroid nodule diameter >1 cm is superior to the nodule with diameter ≤ 1 cm.
