多普勒超声血流动力学指标对甲状腺癌的评估价值

Study on the value of doppler ultrasound in evaluating the hemodynamic parameters in patients with thyroid cancer

[目的]探讨多普勒超声血流动力学指标对甲状腺癌的评估价值。[方法]选自2017年12月到2019年12月在某医院住院治疗的甲状腺癌患者作为观察组(n=71),同期选取我院诊治的良性甲状腺肿瘤患者作为对照组(n=68)。对比各组患者血流动力学关于血流频谱收缩期峰值速度(S)、舒张末期血流速度(D)、搏动指数(PI)和阻力指数(RI)指标。[结果]观察组S、D指标明显高于对照组,组间比较差异明显(P<0.05);观察组PI、RI指标明显低于对照组,组间比较差异明显(P<0.05)。[结论]多普勒超声检查对甲状腺结节的良、恶性判断有重要价值,在甲状腺声像图的基础上,结合血流动力学S、D、PI、RI指标数据及患者临床资料,可为临床医师提供更可靠和有价值的参考依据。

[Objective]To evaluate the value of doppler ultrasound in evaluating the hemodynamic parameters of patients with thyroid cancer.[Methods]Patients with thyroid cancer hospitalized in one hospital from December 2017 to December 2019 were selected as the observation group(n=71),and patients with benign thyroid tumor-diagnosed and treated in our hospital were selected as the control group at the same time(n=68).The hemodynamics of patients in each group were compared with the systolic peak velocity(S),end-diastolic velocity(D),pulse index(PI)and resistance index(RI).[Results]The S and D indexes of the observation group were significantly higher than those of the control group,and the differences between groups were significant(P<0.05).The PI and RI indexes in the observation group were significantly lower than those in the control group,and the differences between the groups were significant(P<0.05).[Conclusion]It is value in the diagnosis of benign and malignant thyroid nodules by using doppler ultrasonography.On the basis of thyroid ultrasonography,combined with hemodynamic S,D,PI,RI index data and patient clinical data,it can provide clinicians with more reliable and valuable reference basis.
