摘　　要：目的:研究分析彩色多普勒超声(CDFI)与高频超声检查在甲状腺良恶性结节诊断中的影像学表现。方法:选取2022年1月~2023年10月在本院收治的94例甲状腺结节患者作为研究对象,所有患者均采取CDFI与高频超声检查,将病理检查结果作为金标准,对比分析检查结果。结果:经病理检查显示,良性、恶性结节分别为64例、30例,占比分别为62.50%、31.91%。良性组与恶性组的TI-RADS分级对比存在明显差异(P<0.05);淋巴结节转移、内部低回声、周围无回声、钙化灶、边界模糊良性组低于恶性组(P<0.05);血流分级、RI、PSV对比良性组低于恶性组(P<0.05)。敏感度、特异度、准确度、阳性预测值、阴性预测值高频超声、CDFI、联合诊断三种诊断方式对比均是联合诊断更高(P<0.05)。结论:在甲状腺良恶性结节诊断中,采用高频超声与CDFI诊断均有着确切应用优势,而联合诊断能够进一步提高诊断准确性,有效鉴别甲状腺结节性质。Objective:To study and analyze the imaging manifestations of color Doppler ultrasound(CDFI)and high-frequency ultrasound in the diagnosis of benign and malignant thyroid nodules.Methods:94 patients with thyroid nodules admitted to our hospital from January 2022 to October 2023 were selected as the study subjects.All patients underwent CDFI and high-frequency ultrasound examinations,and the pathological examination results were used as the gold standard for comparative analysis of the examination results.Results:According to pathological examination,there were 64 cases of benign and 30 cases of malignant nodules,accounting for 62.50%and 31.91%respectively.There was a significant difference in TI-RADS grading between the benign group and the malignant group(P<0.05);The benign group with lymph node metastasis,internal hypoechogenicity,absence of surrounding echoes,calcification,and blurred boundaries was lower than the malignant group(P<0.05);Blood flow classification,RI,and PSV were lower in the benign group than in the malignant group(P<0.05).The comparison of sensitivity,specificity,accuracy,positive predictive value,negative predictive value,high-frequency ultrasound,CDFI,and combined diagnosis among the three diagnostic methods showed that combined diagnosis had higher values(P<0.05).Conclusion:In the diagnosis of benign and malignant thyroid nodules,both high-frequency ultrasound and CDFI have definite application advantages,and combined diagnosis can further improve diagnostic accuracy and effectively distinguish the nature of thyroid nodules.
