摘　　要：目的:探讨超声鉴别诊断甲状腺良恶性结节的应用价值。方法:回顾性分析我院2019年5月至2022年5月期间接受甲状腺超声检查且最终获得手术病理结果的220例甲状腺患者。将超声诊断与术后病理结果比较,明确超声诊断的灵敏度、特异度及准确性,以病理结果为金标准,绘制ROC曲线图,分析其在基层医院的优势。结果:超声诊断甲状腺结节良恶性的灵敏度98.35%,特异度97.37%,准确性98.18,阳性预测值99.44%,阴性预测值92.5%。其AUC为0.979(95%CI:0.947-1.000,P<0.001)。甲状腺恶性病变的多项超声特征(形态、内部回声、纵横比、微钙化、边界及血流)与良性病灶比较,差异有统计学意义(P<0.05)。结论:超声鉴别诊断甲状腺病变的良恶性效果极佳,具有非常好的诊断效能。Objective:to explore the advantage of ultrasonography in dfferentiating benign and malignant thyroid nodules:Methods:A retrospective analysis of 220 patients who underwent thyroid ultrasonography and received operation in our hospital from May 2019 to May 2022 was carried out.The sensitivity,specificity and accuracy of ultrasonic diagnosis were confirmed by comparing the ultrasonic diagnosis with the postoperative pathological results.According to the pathological results,the ROC curve was drawn and the advantages of ROC were analyzed.Results:The sensitivity,specificity,accuracy,positive predictive value and negative predictive value of ultrasonography in the diagnosis of benign and malignant thyroid nodule were 98.35%,97.37%,98.18%,99.44%and 92.5%,respectively.The AUC was 0.979(95%CI:0.947-1.000,P<0.001).There were significant differences between malignant and benign thyroid lesions in many ultrasonic features(shape,internal echo,aspect ratio,microcalcification,boundary,and blood flow)(P<0.05).Conclusion:Ultrasonography is an effective method in the diferential diagnosis of thyroid diseases.
