ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the contrast-enhanced ultrasound(CEUS) and ultrasonic elastography (UE) in diagnosis of thyroid nodules by a binary Logistic regression model.</p><p><b>METHODS</b>A total 149 cases with thyroid nodules were examed by CEUS and UE and were confirmed by surgical pathology. A Logistic model was obtained on the basis of ultrasonographic features. Receiver operator characteris(ROC) curve was constructed to assess the performance of the Logistic model.</p><p><b>RESULTS</b>Four ultrasonographic features including calcification, enhancement degree, biggest perfusion strength and elastic score were finally entered into the Logistic model. The percentage of correct prediction was 91.90%.</p><p><b>CONCLUSION</b>Both CEUS and UE have high value in differential diagnosis of thyroid nodules and the Logistic regression model has high diagnostic rate.</p>
