【摘要】：目的探讨超声弹性成像对甲状腺结节TI-RADS分类的诊断价值,以及不同医师间诊断的一致性。方法由两名医师分别独立对127个甲状腺结节的常规超声及弹性图像进行回顾性分析,比较TI-RADS分类和结合弹性成像的TI-RADS分类对甲状腺结节恶性风险的评估能力。结果 (1)超声医师A得到的TI-RADS分类的准确度和特异度分别为75.59%、71.79%,结合弹性成像后TI-RADS分类的准确度和特异度分别为86.61%、87.18%,两者间差异有统计学意义。超声医师B得到的TI-RADS分类的准确度和特异度分别为77.95%、74.36%,结合弹性成像后TI-RADS分类的准确度和特异度分别为88.19%、88.46%,两者间差异有统计学意义。(2)两名超声医师的诊断准确度差异无统计学意义,两者诊断具有中等一致性(Kappa值分别为0.569、0.682)。结论甲状腺弹性成像有助于提高TI-RADS分类对甲状腺结节恶性风险评估能力。
[Abstract]:Objective to evaluate the diagnostic value of ultrasound elastic imaging (EUS) in TI-RADS classification of thyroid nodules and the consistency between different physicians. Methods the routine ultrasound and elastic images of 127 thyroid nodules were analyzed retrospectively by two physicians, and the ability of TI-RADS classification and TI-RADS classification combined with elastic imaging to evaluate the malignant risk of thyroid nodules was compared. Results 1) the accuracy and specificity of TI-RADS classification obtained by ultrasound physician A were 75.599.The accuracy and specificity of TI-RADS classification after elastic imaging were 86.61 and 87.18, respectively. The difference between the two groups was statistically significant. The accuracy and specificity of TI-RADS classification obtained by ultrasound physician B were 77.950.The accuracy and specificity of TI-RADS classification after elastic imaging were 88.19 and 88.46, respectively. The difference between the two ultrasound doctors was statistically significant. There is no statistical significance. The Kappa values were 0.569 and 0.682n, respectively. Conclusion thyroid elastography can improve the ability of TI-RADS classification to evaluate the malignant risk of thyroid nodules.
