摘　　要：目的探究彩色多普勒超声在甲状腺结节良恶性鉴别诊断中的应用价值。方法选择2020年6月至2021年6月在我院接受治疗的80例甲状腺结节患者作为研究对象,根据病理学检查结果将其分为良性组(61例)、恶性组(19例)。两组均行彩色多普勒超声检查,并对两组的检查结果进行比较。结果以病理学检查结果为金标准,彩色多普勒超声诊断甲状腺结节的准确度为93.75%(75/80)。良性组的结节直径<2 cm、无钙化、边界清晰、血流缺乏的占比高于恶性组(P<0.05)。良性组的血流Ⅰ型、Ⅱ型占比高于恶性组,血流Ⅲ型、Ⅳ型占比低于恶性组,差异具有统计学意义(P<0.05)。良性组的收缩期峰值血流速度(PSV)、阻力指数(RI)低于恶性组,舒张末期血流速度(EDV)高于恶性组,差异具有统计学意义(P<0.05)。结论彩色多普勒超声可以将甲状腺结节患者的血流情况、结节形态、直径等清晰地呈现出来,从而对良恶性结节进行有效鉴别。Objective To explore the application value of color Doppler ultrasound in the differential diagnosis of benign and malignant thyroid nodules.Methods Eighty patients with thyroid nodules who were treated in our hospital from June 2020 to June 2021 were selected as the research objects.According to the results of pathological examination,the patients were divided into benign group(61 cases)and malignant group(19 cases).Both groups were examined by color Doppler ultrasound,and the examination results of the two groups were compared.Results With the pathological examination results as the gold standard,the accuracy of color Doppler ultrasound in the diagnosis of thyroid nodules were 93.75%(75/80).The proportion of nodules with diameter<2 cm,no calcification,clear boundary and lack of blood flow in the benign group were higher than those in the malignant group(P<0.05).The proportion of blood flow typeⅠand typeⅡin the benign group were higher than those in the malignant group,the proportion of blood flow typeⅢand typeⅣwere lower than those in the malignant group,and the differences were statistically significant(P<0.05).The peak systolic velocity(PSV)and resistance index(RI)in the benign group were lower than those in the malignant group,the end diastolic velocity(EDV)was higher than that in the malignant group,and the differences were statistically significant(P<0.05).Conclusion Color Doppler ultrasound can clearly present the blood flow,nodule morphology and diameter of patients with thyroid nodules,so as to effectively identify benign and malignant nodules.
