【摘要】 目的 研究二维超声与彩色多普勒超声诊断甲状腺良恶性结节的价值。方法 选取2020年4月-2021年4月我院经手术病理确诊的74例甲状腺结节患者为研究对象，均进行二维超声及彩色多普勒超声检查，比较二维超声与彩色多普勒超声的诊断准确率、良恶性超声征象分布特点，二维超声与彩色多普勒超声及二维超声联合彩色多普勒超声诊断的敏感度、特异度。结果 二维超声联合彩色多普勒超声诊断甲状腺良性、恶性结节的准确率均高于二维超声、彩色多普勒超声诊断，且彩色多普勒超声诊断高于二维超声诊断，差异有统计学意义（P<0.05）；二维超声诊断良性结节边界清晰、囊实质、形态规则发生率均高于恶性结节患者，低回声、微钙化发生率低于恶性结节患者，差异有统计学意义（P<0.05）；彩色多普勒超声诊断，良性结节Ⅰ级血流信号发生率均高于恶性结节，Ⅱ、Ⅲ级血流信号发生率低于恶性结节，差异有统计学意义（P<0.05）；二维超声联合彩色多普勒超声诊断敏感度、特异度均高于二维超声、彩色多普勒超声单独诊断，且彩色多普勒超声诊断高于二维超声诊断，差异有统计学意义（P<0.05）。结论 二维超声联合彩色多普勒超声诊断甲状腺良恶性结节敏感度、特异度均较高，具有重要的临床价值，可为临床甲状腺良恶性结节鉴别诊断提供可靠的参考依据。更多还原

【Abstract】 Objective To study the value of two-dimensional ultrasound and color Doppler ultrasound in the diagnosis of benign and malignant thyroid nodules.Methods A total of 74 patients with thyroid nodules diagnosed by surgery and pathology in our hospital from April 2020 to April 2021 were selected as the research objects. All patients underwent two-dimensional ultrasound and color Doppler ultrasound. The diagnostic accuracy of two-dimensional ultrasound and color Doppler ultrasound, the distribution characteristics of benign and malignant ultrasound signs, the sensitivity and specificity of two-dimensional ultrasound and color Doppler ultrasound and two-dimensional ultrasound combined with color Doppler ultrasound were compared.Results The accuracy of two-dimensional ultrasound combined with color Doppler ultrasound in the diagnosis of benign and malignant thyroid nodules was higher than that of two-dimensional ultrasound and color Doppler ultrasound, and the diagnosis of color Doppler ultrasound was higher than that of two-dimensional ultrasound, the difference was statistically significant(P<0.05). The incidence of clear boundary, cystic parenchyma and regular morphology of benign nodules diagnosed by two-dimensional ultrasound was higher than that of malignant nodules, and the incidence of hypoechoic and microcalcifications was lower than that of malignant nodules, and the difference was statistically significant(P<0.05). The incidence of grade Ⅰ blood flow signals in benign nodules was higher than that in malignant nodules, and the incidence of grade Ⅱ and Ⅲ blood flow signals was lower than that in malignant nodules, the difference was statistically significant(P<0.05). The diagnostic sensitivity and specificity of two-dimensional ultrasound combined with color Doppler ultrasound were higher than those of two-dimensional ultrasound and color Doppler ultrasound alone, and the diagnosis of color Doppler ultrasound was higher than that of two-dimensional ultrasound(P<0.05).Conclusion The sensitivity and specificity of twodimensional ultrasound combined with color Doppler ultrasound in the diagnosis of benign and malignant thyroid nodules are high, which has important clinical value and can provide reliable reference for the differential diagnosis of benign and malignant thyroid nodules.更多还原
