摘要
目的探讨良恶性甲状腺结节采取彩色多普勒超声的诊断效果。方法研究对象为2019年11月至2020年11月在我院收治的90例甲状腺结节患者,对全部患者采取彩色多普勒超声检查,将手术病理结果作为金标准,对良恶性甲状腺结节的超声表现、诊断效果以及血流参数[血流收缩期峰值流速(PSV)、阻力指数(RI)、舒张末期血流速度(EDV)]进行比较。结果彩色多普勒超声诊断良恶性甲状腺结节的灵敏度为80.00%(20/25)、特异度为96.92%(63/65)、准确率为92.22%(83/90)。恶性结节的纵横比<1、边界模糊、结节内部低回声、结节内部钙化的占比均高于良性结节(P<0.05)。恶性结节PSV、RI高于良性结节(P<0.05),ESV低于良性结节(P<0.05)。结论对良恶性甲状腺结节采取彩色多普勒超声诊断效果确切,值得推广。
Objective To investigate the effect of color Doppler ultrasound in the diagnosis of benign and malignant thyroid nodules.Methods A total of 90 patients with thyroid nodules in our hospital from November 2019 to November 2020 were studied.All patients were examined by color Doppler ultrasound,and the surgical pathological results were taken as the gold standard.The ultrasound performance,diagnostic effect and blood flow parameters of benign and malignant thyroid nodules[peak systolic velocity(PSV),resistance index(RI),blood flow velocity(PSV),resistance index(RI)were analyzed end diastolic blood flow velocity(EDV)].Results The sensitivity,specificity and accuracy of color Doppler ultrasound in the diagnosis of benign and malignant thyroid nodules were 80.00%(20/25),96.92%(63/65)and 92.22%(83/90).The proportion of malignant nodules with aspect ratio<1,fuzzy boundary,hypoechoic and calcification inside the nodules was higher than that of benign nodules(P<0.05).PSV and RI of malignant nodules were higher than those of benign nodules(P<0.05),ESV was lower than that of benign nodules(P<0.05).Conclusion Color Doppler ultrasound diagnosis of benign and malignant thyroid nodules is effective and worthy of promotion.
