To explore the effectiveness of two-dimensional ultrasound and color Doppler ultrasound in diagnosing benign and malignant thyroid nodules. The subjects of this study were 193 patients with thyroid nodules admitted to our hospital from January 1, 2019 to January 1, 2023. Provide all patients with two-dimensional ultrasound, color Doppler ultrasound, and a combination of two types of ultrasound examination, and analyze the results of two-dimensional ultrasound, color Doppler ultrasound, and a combination of two types of ultrasound examination for benign and malignant thyroid nodules based on pathological examination results. According to the pathological examination, among the 193 patients with thyroid nodules, 144 were benign nodules and 49 were malignant nodules. The coincidence rate, sensitivity, and specificity of the combined examination of two-dimensional ultrasound and color Doppler ultrasound were higher than those of a single examination of two-dimensional ultrasound and color Doppler ultrasound (P<0.05). The detection rates of benign nodules with clear boundaries, solid nodule cysts, and regular morphology are higher than those of malignant nodules using two-dimensional ultrasound and color Doppler ultrasound; the detection rates of low echo and microcalcification in benign nodules using two-dimensional ultrasound and color doppler ultrasound were lower than those of malignant nodules (P<0.05). The proportion of benign nodules with type I, II, and III blood flow classification on color Doppler ultrasound was higher than that of malignant nodules, while the proportion of type IV blood flow classification was lower than that of malignant nodules (P<0.05). Compared to a single examination using two-dimensional ultrasound and color Doppler ultrasound, the combined examination of the two has higher diagnostic accuracy for benign and malignant thyroid nodules, which is feasible for clinical promotion.
