Objective To analyze and discuss the application effect of color Doppler ultrasound in patients with thyroid nodules. Methods: 82 patients (98 nodules) with thyroid sarcoidosis in our hospital from September 2021 to August 2022 were selected for color Doppler ultrasound examination. Based on the follow-up diagnosis results, the differential effect of color Doppler ultrasound on benign and malignant nodules was analyzed, and the ultrasonic imaging manifestations of different properties and nodules were analyzed. Results:Of the 98 nodules in 82 patients, 70 were benign and 28 were malignant. The sensitivity, specificity and accuracy of color Doppler ultrasound in differential diagnosis of benign and malignant nodules were 92.86％, 82.14％ and 89.80％ respectively. The shape, echo, boundary, calcification and blood flow of benign nodules were significantly different from those of malignant nodules (P＜0.05). Resistance index (RI), pulsatility index (PI) and diastolic minimum blood flow velocity (D) of malignant nodules were significantly higher than those of benign nodules (P＜0.05). Conclusion: According to the ultrasonic manifestations of thyroid nodules with different natures, it can provide important reference for clinical differentiation of benign and malignant thyroid nodules.
