Objective: To study the diagnostic value of color doppler ultrasound in children with thyroid nodules and thyroid cancer. Methods: A total of sixty children with thyroid nodules treated in our hospital from March 2017 to March 2018 were selected for study. All patients underwent color Doppler ultrasound diagnosis. According to the diagnostic data, benign thyroid nodules and thyroid cancer were analyzed. The nodule nature was grouped into benign nodules group and malignant nodules group. The aspect ratio and boundary of the two groups were compared in blurring, calcification, blood flow signal classification, etc. Results: A total of 95 nodules were diagnosed by color doppler ultrasonography in 60 cases of thyroid nodules. 49 cases were benign nodules. There were 80 nodules, accounting for 82.11%, 11 cases of thyroid cancer, and 15 nodules. Accounted for 15.79%. Biopsy puncture pathology confirmed 77 benign nodules and 18 malignant nodules. The pathological results were gold standard. The specificity of color Doppler ultrasound was 90%, the sensitivity was 66.67%, and the accuracy of ultrasound diagnosis was 86.32%.The two nodules were statistically significant in terms of boundary, aspect ratio, calcification, echo, and resistance index (P<0.05), but the end-diastolic blood flow velocity (EDV) and peak systolic blood flow velocity ( There was no statistical difference between the PSV levels (P>0.05).Conclusion: Color Doppler ultrasound has the advantages of simple operation, high accuracy, non-invasive and painless, and reproducible detection. The high-frequency probe can clearly display changes such as minute lesions, blood flow signals, echoes, calcifications, etc., and can diagnose thyroid cancer in time. It provides a favorable basis for clinical treatment and has important clinical warning value, especially for children with thyroid examination.
