To compare the effectiveness of conventional ultrasonography and ultrasound elastography in differential diagnosis of thyroid nodular diseases.
244 patients with 291 thyroid nodules were examined by ultrasonography and ultrasound elastography respectively; the examination results were compared against pathological findings to determine the effectiveness of these two examination methods.
The sensitivity and positive predictive value of conventional ultrasonography is higher than those of ultrasound elastography, but its specificity, accuracy, and negative predictive value is lower than those of the later.
Ultrasound elastography is superior to conventional ultrasonography in differential diagnosis of thyroid nodules. However, ultrasonography is the basis of examination; only on this basis, an additional ultrasound elastography examination could greatly improve the diagnostic rate of thyroid nodular diseases.
比较常规超声及超声弹性成像在甲状腺结节性疾病鉴别诊断中的应用效果。
对 244 例 291 个甲状腺结节患者分别进行常规超声及超声弹性成像检查，将检查结果与病理结果进行对照，评价两种检查方法的效能。
常规超声的灵敏度及阳性预测值均高于超声弹性成像，但特异度、准确率及阴性预测值均低于超声弹性成像。
超声弹性成像在甲状腺结节的鉴别诊断中优于常规超声，但超声检查是基础，在此基础上增加超声弹性成像检查可显著提高甲状腺结节性疾病的诊断率。
