| 摘要: |
| 目的：评估应变弹性成像技术在甲状腺结节良恶性鉴别诊断中的应用价值。方法：对收入我院进行检查的31例患者31个甲状腺结节进行常规超声及弹性成像检查，分析弹性评分法及SR比值法对甲状腺良恶性结节的检出率情况，并分别计算三种方法在甲状腺良恶性结节鉴别诊断中的灵敏度、特异度、阳性预测值、阴性预测值。结果：31个甲状腺结节，经病理检查良性结节15个，恶性结节16个。弹性评分法及SR比值法阳性检出率均高于常规超声；弹性评分法及SR比值法的灵敏度、特异度、阳性预测值、阴性预测值均高于常规超声。结论：弹性成像技术有助于鉴别诊断甲状腺结节的良恶性。 |

| Abstract: |
| Objective：To assess the value of elastography in differentiation diagnosis of malignant and benign thyroid nodule.Methods:Thrity-one patients with 31 lesions were examined by Ultrasound and elastography.Analyse the detection rate and calculate the sensitivity, specificity,positive predictive value and negative predictive value of Ultrasound and elastography.Result：In 31 cases of thyroid nodules，15 were malignant nodules, 16 were benign nodules.The positive rate of the elasticity scores and elasticity strain ratio were significantly higher than that in the Ultrasound.And the predictive value, judging for the sensibility, specificity, masculine and negative of the elasticity scores and elasticity strain ratio were significantly higher than that in the Ultrasound.Conclude:The elastograpy is helpful in differentiating benign and malignant thyroid nodules. |
