目的实性甲状腺良、恶性小结节行超声弹性成像鉴别诊断的临床评价与分析。方法选取2013年9月—2014年6月期间收治的124例患者(230个甲状腺实性结节)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。同时根据4分法(1~4分)来评价甲状腺结节弹性,良性结节:≤2分;恶性结节:≥3分。并以临床病理结果为诊断金标准,然后分别计算甲乙两组诊断敏感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、乙两组敏感度和准确度、阳性预测值、阴性预测值比较(P<0.05);而特异度比较(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 evaluate the clinical value of differential diagnosis of benign and malignant thyroid nodules by ultrasound elastography. Methods Totally 124 patients (230 thyroid solid nodules) who were admitted between September 2013 and June 2014 were examined by ultrasound elastography. According to the length of the nodule group, where Group A: long diameter ≤ 1.0cm, Group B: long diameter> 1.0cm. At the same time according to 4 points method (1 to 4 points) to evaluate thyroid nodule elasticity, benign nodules: ≤ 2 points; malignant nodules: ≥ 3 points. And the clinical and pathological results for the diagnosis of gold standard, and then calculate the diagnostic sensitivity and specificity of the two groups A and B, the positive predictive value, negative predictive value. Results The study found that, A, B two groups of sensitivity and accuracy, positive predictive value, negative predictive value (P <0.05); and specificity (P> 0.05). Conclusion Ultrasound elastography is of high value in differential diagnosis of small thyroid nodules (diameter ≤ 1.0cm).
