甲状腺结节的超声诊断应用价值

Application Value of Ultrasonography in the Diagnosis of Thyroid Nodules

目的:探索分析超声对甲状腺结节的诊断价值。方法:随机选取2014年10月-2015年5月来笔者所在医院就诊的甲状腺结节患者240例,根据患者结节的大小,分为1 cm以上组、1 cm及以下组,对患者行超声检查,利用ROC曲线对超声诊断的应用价值进行评价。结果:良恶性甲状腺结节在形态、边缘情况、血流及内部回声等方面比较差异均有统计学意义(P<0.05)。当结节直径不超过1 cm时,特异度、灵敏度分别为90.9%、90.0%,准确率为90.8%,最佳临界值为3分;当结节直径大于1 cm时,特异度、灵敏度为94.7%、77.8%,准确率为91.5%,最佳临界值为2分。结论:超声检查对于甲状腺结节的诊断,不仅能够鉴别甲状腺结节的良恶性,而且费用较低,具有较高的诊断价值。

Objective： To explore the diagnostic value of ultrasound for thyroid nodules.Method： 240 patients with thyroid nodules in our hospital from October 2014 to May 2015 were randomly selected, according to the size of the nodule patients were divided into more than 1 cm group and less than or equal to I cm group.All patients were given ultrasound examination, the ROC curve was used to evaluate the value of ultrasonic diagnosis.Result： The differences in morphology, edge cases, blood flow and internal echo comparative between benign and malignant thyroid nodules were statistically significant（P〈0.05）.When the nodule diameter was not greater than 1 cm, the specificity, sensitivity was 90.9%, 90.0% respectively, the accuracy rate was 90.8%, the optimal cutoff value was 3 points.When the nodule diameter was greater than 1 cm, the specificity, sensitivity was 94.7%, 77.8% respectively, the accuracy was 91.5%, the best critical value was 2 points.Conclusion： The uhrasonography for the diagnosis of thyroid nodules is not only able to identify benign and malignant thyroid nodules, but also with low cost, it has a high diagnostic value.
