目的:探讨超声诊断在甲状腺结节良恶性诊断及鉴别中的应用价值。方法:随机选取2010年10月-2014年10月重庆市垫江县人民医院收治的甲状腺结节患者405例,甲状腺结节431个,根据结节大小不同,分为>1 cm组与≤1 cm组,均行超声检查诊断,并用ROC曲线评价超声诊断的应用价值。结果:结节>1 cm时,最佳临界值为2,超声诊断灵敏度、特异度及准确度分别为70.97%、92.6%及90.73%,;当结节≤1 cm,最佳临界值为3,超声诊断灵敏度、特异度及准确度分别为80%、93.58%及92.0%。结论:在甲状腺结节的临床诊断中,超声诊断的价值较高,可有效鉴别甲状腺结节的良恶性。
Objective: To investigate the value of ultrasonic diagnosis in the diagnosis and differential diagnosis of benign and malignant thyroid nodules. Methods: 405 cases of thyroid nodules and 431 thyroid nodules were randomly selected from Dianjiang People’s Hospital of Chongqing from October 2010 to October 2014. According to the size of nodules, they were divided into> 1 cm group and ≤1 cm group, were diagnosed by ultrasound, and the use of ROC curve evaluation of diagnostic value of ultrasound. Results: The best cutoff value was 2 when the nodule was> 1 cm, the sensitivity, specificity and accuracy of ultrasonic diagnosis were 70.97%, 92.6% and 90.73% respectively. When the nodule was less than 1 cm, the best cutoff value was 3 The sensitivity, specificity and accuracy of ultrasonic diagnosis were 80%, 93.58% and 92.0% respectively. Conclusion: In the clinical diagnosis of thyroid nodules, ultrasound diagnosis of high value, which can effectively identify the benign and malignant thyroid nodules.
