彩色多普勒超声在甲状腺结节良恶性鉴别中的应用

The Application of CDU in the Differentiation of Benign and Malignant Thyroid Nodules

目的:探究彩色多普勒超声在甲状腺结节良恶性鉴别中的应用价值。方法:选择2017年1月~2019年10月凌海市人民医院诊治的甲状腺结节患者,共76例,按照病理诊断结果分组,其中良性患者设定为对照组40例,恶性患者设定为观察组共36例,全部患者均接受彩色多普勒超声诊断,比较两组的血流信号情况和血流动力学参数。结果:观察组边界清晰、形态规则占比分别为8.33%、5.56%,均低于对照组62.50%、65.00%,观察组微钙化、低回声、Ⅲ级血流占比分别为66.67%、72.22%、75.00%,均高于对照组20.00%、25.00%、20.00%,P<0.05;观察组阻力指数(RI)、收缩期峰值流速(PSV)大于对照组,舒张末期血流速度(EDV)小于对照组,P<0.05。结论:针对甲状腺结节患者,彩色多普勒超声能够准确鉴别结节良恶性,为临床诊治工作提供科学依据。

Objective:To explore the value of CDU in the differential diagnosis of benign and malignant thyroid nodules.Methods:A total of 76 patients with thyroid nodule diagnosed and treated in Linghai people’s Hospital from January 2017 to October 2019 were selected.According to the pathological diagnosis results,they were divided into two groups:the control group(the benign cases),and the experimental group(the malignant cases).All patients were examined by CDU.The blood flow signals and hemodynamic parameters of the two groups were compared.Results:The proportion of clear boundary and regular shape in the experimental group was 8.33%and 5.56%respectively,which were lower than 62.50%and 65.00%in the control group.The proportion of micro calcification,low echo and grade III blood flow in the experimental group were 66.67%,72.22%and 75.00%,which were higher than 20.00%,25.00%and 20.00%in the control group,P<0.05.The resistance index(RI)and peak systolic velocity(PSV)in the experimental group were higher than those in the control group,and the ratio of end diastolic blood flow was higher than that in the control group The blood flow velocity(EDV)was lower than that of the control group(P<0.05).Conclusion:For patients with thyroid nodules,color Doppler ultrasound can accurately identify benign and malignant nodules,and provide scientific basis for clinical diagnosis and treatment.
