Abstract

Abstract: In order to explore the diagnostic value of high-frequency ultrasound combined with color Doppler ultrasound in patients with benign and malignant thyroid nodules, 82 patients with suspected thyroid nodules were selected as the research objects. This study compared the results of high frequency ultrasound and color Doppler ultrasound with the pathological results. The ROC curve was drawn, and the diagnostic efficiency of high frequency ultrasound combined with color Doppler ultrasound in patients with benign and malignant thyroid nodules was analyzed. The results showed that the difference between pathology and high-frequency ultrasound combined with color Doppler ultrasound was not statistically significant (P>0.05). High frequency ultrasound distinguished benign and malignant thyroid nodules by their structure, echo, shape, margin and calcification. ROC curve analysis results showed that high-frequency ultrasound combined with color Doppler ultrasound had the highest area under the curve (AUC) in thyroid benign and malignant nodules. Nevertheless, high-frequency ultrasound had the highest specificity (98.33%), and color Doppler Ultrasound had the highest sensitivity (86.36%). In conclusion, high-frequency ultrasound combined with color Doppler ultrasound can effectively improve the diagnostic accuracy of benign and malignant thyroid nodules.

Key words: high-frequency ultrasound, color Doppler ultrasound, benign and malignant thyroid nodules, diagnostic effect, pathological examination
