Methods: From June 2021 to July 2022, 163 patients with thyroid nodules enrolled in our hospital were selected as research subjects. After pathological diagnosis, 24 cases were malignant thyroid nodules, and 139 cases were benign thyroid nodules. The diagnosis rate of malignant and benign thyroid nodules was observed and analyzed, with 95% CI. Results: Among them, the malignant and benign detection rates of routine ultrasound were 88.63% and 75.00%, respectively, and the malignant and benign detection rates of contrast-enhanced ultrasound were 81.82% and 81.25%, respectively. The malignant and benign detection rates of conventional ultrasound combined with contrast-enhanced ultrasound were 93.18% and 87.50%, respectively, and the 95% CI was greater than 0.7. Conclusion: Conventional ultrasound combined with contrast-enhanced ultrasound can help improve the diagnostic accuracy of benign and malignant thyroid nodules and reduce the misdiagnosis rate.
