Objective: To evaluate the contrast-enhanced ultrasound(CEUS) and ultrasonic elastography (UE) in diagnosis of thyroid nodules by a binary Logistic regression model.
Methods: 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.
Results: 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%.
Conclusion: Both CEUS and UE have high value in differential diagnosis of thyroid nodules and the Logistic regression model has high diagnostic rate.
