目的探讨超声弹性成像在不同大小甲状腺结节良恶性鉴别中的应用价值。方法选取本院2014年4月~2015年10月收治的80例患者(100个甲状腺实性结节),均采用超声弹性成像检查。根据结节的长径进行分组,其中甲组:长径≤1.0cm,乙组:长径>1.0cm。比较两组诊断灵敏度和特异度及准确度、阳性预测值、阴性预测值。结果经研究发现,甲、乙两组灵敏度和准确度、阳性预测值、阴性预测值比较差异有统计学意义(P<0.05);而特异度比较差异无统计学意义(P>0.05)。结论采用超声弹性成像对甲状腺小结节(长径≤1.0cm)鉴别诊断具有较高应用价值。
Objective To investigate the value of ultrasound elastography in differentiating benign and malignant thyroid nodules of different sizes. Methods Eighty patients (100 thyroid solid nodules) who were admitted to our hospital from April 2014 to October 2015 were enrolled in this study. All patients underwent ultrasound elastography. According to the length of the nodule group, where Group A: long diameter ≤ 1.0cm, Group B: long diameter> 1.0cm. The diagnostic sensitivity, specificity, accuracy, positive predictive value and negative predictive value of the two groups were compared. Results The study found that the sensitivity and accuracy of the two groups A and B, the positive predictive value and negative predictive value was significantly different (P <0.05), while the specificity was no significant difference (P> 0.05). Conclusion Ultrasound elastography is of high value in differential diagnosis of small thyroid nodules (diameter ≤ 1.0cm).
