彩色多普勒超声与超声弹性成像在甲状腺结节良恶性诊断中的价值

The Value of Color Doppler Ultrasonography and Ultrasound Elastography in the Diagnosis of Benign and Malignant Thyroid Nodules

目的:比较分析彩色多普勒超声与超声弹性成像在甲状腺结节良恶性诊断中的价值。方法:选取2020年6月—2021年6月柳州市工人医院超声科经病理证实为甲状腺结节的患者80例作为研究对象。患者均进行彩色多普勒超声和超声弹性成像检查。比较两种检查方法的甲状腺结节良恶性检出率、甲状腺结节良恶性超声弹性成像评分和甲状腺结节良恶性的诊断效能。结果:经过病理证实的80例甲状腺结节患者中,良性结节62个,恶性结节18个。超声弹性成像诊断符合率高于彩色多普勒超声,差异有统计学意义(P=0.002)。超声弹性成像评分结果对比发现,良性结节评分主要表现在1~2分,而恶性结节评分主要表现在3~4分,差异有统计学意义(P<0.001)。超声弹性成像在诊断甲状腺结节良恶性的灵敏度、特异度及诊断准确率均高于彩色多普勒超声,差异有统计学意义(P<0.05)。结论:超声弹性成像在甲状腺结节良恶性诊断中的价值更高,可提高诊断准确率、灵敏度、特异度,可结合实际情况进行应用,为后续临床诊断和治疗提供依据。

Objective:To compare and analyze the value of color Doppler ultrasonography and ultrasound elastography in the diagnosis of benign and malignant thyroid nodules.Methods:From June 2020 to June 2021,80 patients with thyroid nodules confirmed by pathology in the Department of Ultrasound,Liuzhou Workers Hospital were selected as the research objects.All patients underwent color Doppler ultrasonography and ultrasound elastography.The detection rate of benign and malignant thyroid nodules,the ultrasound elastography score of benign and malignant thyroid nodules and the diagnostic efficiency of benign and malignant thyroid nodules were compared between the two methods.Results:Among the 80 cases of thyroid nodules confirmed by pathology,62 were benign nodules and 18 were malignant nodules.The diagnostic coincidence rate of ultrasound elastography was higher than that of color Doppler ultrasound,and the difference was statistically significant(P=0.002).Comparing the results of ultrasonic elastography scores,it was found that the scores of benign nodules were mainly 1-2 points,while the scores of malignant nodules were mainly 3-4 points,and the difference was statistically significant(P<0.001).The sensitivity,specificity and diagnostic accuracy of ultrasound elastography in the diagnosis of benign and malignant thyroid nodules were higher than those of color Doppler ultrasound,and the difference was statistically significant(P<0.05).Conclusion:Ultrasound elastography has higher value in the diagnosis of benign and malignant thyroid nodules,which can improve the diagnostic accuracy,sensitivity,and specificity,and can be applied in combination with actual conditions to provide a basis for subsequent clinical diagnosis and treatment.
