彩色多普勒超声在甲状腺癌淋巴结转移中应用价值观察

Application value of color Doppler ultrasound in lymph node metastasis of thyroid cancer

目的:探究彩色多普勒超声在甲状腺癌淋巴结转移中应用价值。方法:选取2019年1月—2022年9月于日照市人民医院就诊的92例甲状腺癌患者。按手术病理结果显示是否发生淋巴结转移分为转移组(n=37)和未转移组(n=55)。记录并比较两组患者彩色多普勒超声图像特征、血流分布情况及血流参数,计算彩色多普勒超声诊断甲状腺癌淋巴结转移的特异度和灵敏度。结果:彩超对甲状腺癌淋巴结转移的诊断灵敏度(89.19%)与特异度(94.55%)、准确度(89.47%)均高于二维超声[(70.27%)、(74.55%)、(72.83%)],差异有统计学意义(P<0.05);未转移组甲状腺癌患者的边界不清、淋巴结融合、皮质增厚、淋巴结偏移和纵横比<2的检出率均低于转移组,差异有统计学意义(P<0.05);未转移组甲状腺癌患者的血流分布优于转移组,差异有统计学意义(P<0.05);未转移组患者的PSV、RI值均低于转移组,差异有统计学意义(P<0.05);两组PI值对比,差异无统计学意义(P>0.05)。结论:彩色多普勒超声诊断甲状腺癌淋巴结转移的价值高,结合彩超图像特征及血流信号分型、血流参数等综合分析,能提升临床诊断效能,为后续治疗方案的制定提供科学依据。

Objective To explore the application value of color Doppler ultrasound in lymph node metastasis of thyroid cancer.Methods A total of 92 patients with thyroid cancer were selected from January 2019 to September 2022 in Rizhao People's Hospital.Lymph node metastasis was divided into metastatic group(n=37)and non-metastatic group(n=55)according to pathological results of operation.Color Doppler ultrasound image features,blood flow distribution and blood flow parameters were recorded and compared between the two groups,and the specificity and sensitivity of color Doppler ultrasound in the diagnosis of lymph node metastasis of thyroid cancer were calculated.Results The diagnostic sensitivity(89.19%),specificity(94.55%)and accuracy(89.47%)of color ultrasound for lymph node metastasis of thyroid cancer were higher than those of two-dimensional ultrasound[(70.27%),(74.55%),(72.83%)],the difference was statistically significant(P<0.05).The detection rates of boundary ambiguity,lymph node fusion,cortical thickening,lymph node migration and aspect ratio<2 in the non-metastatic group were lower than those in the metastatic group,with statistical significance(P<0.05).The blood flow distribution of thyroid cancer patients in the non-metastatic group was better than that in the metastatic group,and the difference was statistically significant(P<0.05).The PSV and RI values of patients without metastasis were lower than those of patients with metastasis,and the difference was statistically significant(P<0.05).There was no significant difference in PI values between the two groups(P>0.05).Conclusion Color Doppler ultrasound is of high value in the diagnosis of lymph node metastasis of thyroid cancer.Combined with the comprehensive analysis of color Doppler image features,blood flow signal typing and blood flow parameters,it can improve the clinical diagnosis efficiency and provide scientific basis for the formulation of follow-up treatment plans.
