Abstract:Objective To investigate the effect of two-dimensional ultrasound scoring combined with contrast-enhanced ultrasonography in the differential diagnosis of benign and malignant thyroid nodules.Methods A total of 390 patients with suspected thyroid nodules treated in our hospital from September 2016 to December 2018 were selected, and diagnosed by two-dimensional ultrasound and contrast-enhanced ultrasound.The gold standard was postoperative pathology.The clinical value of the two examination methods was analyzed.Results There were 446 thyroid nodules in 390 patients, including 148 malignant nodules and 298 benign nodules.The two-dimensional ultrasound scoring method had a specificity of 76.5% (228/298), a sensitivity of 90.5% (134/148), and an accuracy of 81.2% (362/446).The contrast-enhanced ultrasound was 80.5% (240/298), the sensitivity was 91.9% (136/148), and the accuracy was 84.3% (376/446).The combined specificity of the two diagnostic methods was 93.3% (278/298), the sensitivity was 91.9% (136/148), and the accuracy was 92.8% (414/446).Conclusion Two-dimensional ultrasound scoring combined with contrastenhanced ultrasound can effectively improve the detection rate of patients with thyroid nodules, which is worthy of popularization.
