高频超声、彩色多普勒超声联用对甲状腺良/恶性结节的诊断价值分析

Analysis of the Diagnostic Value of High-Frequency Ultrasound and Color Doppler Ultrasound in the Diagnosis of Benign and Malignant Thyroid Nodules

目的:研究甲状腺良/恶性结节诊断中应用高频超声联合彩色多普勒超声的价值。方法:选取本院门诊接收的疑似甲状腺良/恶性结节的患者60例,时间为2019年1月~2020年1月,患者均应用高频超声联合彩色多普勒超声检查,以术后病理结果为金标准,比较诊断准确率、诊断效能、良恶性结节血流动力学指标及其超声声像图特点。结果:高频超声联合彩色多普勒超声组诊断准确率91.67%(55/60),灵敏度95.12%(39/41),特异度84.21%(16/19),阳性预测值92.86%(39/42),阴性预测值88.89%(16/18)。良性结节RI、PSV指标低于恶性结节,且EDV指标高于恶性结节,恶性结节组微钙化灶、内部低回声、边界不整、淋巴结转移高于良性结节组,周围无回声低于良性结节组,差异显著(P<0.05)。结论:甲状腺良/恶性结节应用高频超声联合彩色多普勒超声检查具有较高的诊断准确率,可为临床对患者病情的评估提供有利参考。

Objective:To study the value of high-frequency ultrasound combined with color Doppler ultrasound in the diagnosis of benign/malignant thyroid nodules.Methods:60 patients with suspected benign/malignant thyroid nodules were selected from the outpatient department of our hospital from January 2019 to January 2020.All patients were examined by high-frequency ultrasound combined with color Doppler ultrasound.Taking the postoperative pathological results as the gold standard,the diagnostic accuracy,diagnostic efficacy,hemodynamic indexes of benign and malignant thyroid nodules and the characteristics of ultrasonic images were compared.Results:In the high-frequency ultrasound combined with color Doppler ultrasound group,the diagnostic accuracy was 91.67%(55/60),the sensitivity was 95.12%(39/41),the specificity was 84.21%(16/19),the positive predictive value was 92.86%(39/42),and the negative predictive value was 88.89%(16/18).The RI and PSV indexes of benign nodules were lower than those of malignant nodules,and the EDV indexes were higher than those of malignant nodules.The microcalcification,internal low echo,irregular boundary and lymph node metastasis in malignant nodules group were higher than those in benign nodules group,and the peripheral no echo was lower than that in benign nodules group(P<0.05).Conclusion:The application of high-frequency ultrasound combined with color Doppler ultrasound in the diagnosis of benign/malignant thyroid nodules has a high diagnostic accuracy,which can provide a favorable reference for the clinical evaluation of patients’condition.
