Application of color Doppler ultrasound in differential diagnosis of benign and malignant thyroid nodules

Objective To explore the application value of color Doppler ultrasound in differential diagnosis of benign and malignant thyroid nodules, and to provide reliable information for qualitative diagnosis of thyroid nodules. Methods The ultrasonic data of 105 patients with thyroid nodules confirmed by surgery and pathology were analyzed retrospectively, then their sonogram features were summarized. Results In 105 cases, there were 71 cases of benign nodules, 34 cases of malignant tumors. The ultrasonic diagnose accordance rate was 81.9% , and 18 cases were misdiagnosed （17.1%）. Compared the low echo in benign and malighant nodules, there was significant difference （ P 〈 0.05 ）. Conclusion Ultrasonography is the first imaging method in examing thyroid nodules, but it is limited in differential diagnosis of malignant and benign nodule.
