摘要
目的探讨超声对甲状腺良恶性结节诊断中的应用价值。方法选取2019年12月至2021年4月本院收治的106例甲状腺结节患者作为研究对象,所有患者均行超声检查,以手术病理学检查作为金标准,分析超声与手术病理学检查甲状腺良恶性结节的结果,比较良性结节与恶性结节的超声影像学特征及血流动力学参数。结果手术病理学检查发现病灶138个,其中良性结节78个,恶性结节60个。超声检查,真阴性76例,真阳性57例。超声诊断甲状腺良恶性结节的灵敏度为95.00%、特异度为97.44%、准确率为96.38%,与手术病理结果接近。恶性结节超声影像学特征无钙化、无回声、高回声、边界清晰及血流信号周边丰富、无信号占比均低于良性结节,砂粒体样微钙化、低回声、血流信号内部丰富占比均高于良性结节,差异有统计学意义(P<0.05);良恶性结节粗大钙化占比比较差异无统计学意义。恶性结节收缩期峰值血流速度(PSV)快于良性结节,阻力指数(RI)大于良性结节,差异有统计学意义(P<0.05)。结论超声在甲状腺良恶性结节的诊断中具有较好的应用价值,可为甲状腺良恶性结节的鉴别提供丰富的病理信息,有助于提高其诊断准确性,值得临床推广应用。
Objective To investigate the application value of ultrasound in the diagnosis of benign and malignant thyroid nodules.Methods 106 patients with thyroid nodules admitted to our hospital from December 2019 to April 2021 were selected as the research subjects,all patients underwent ultrasound examination,and surgical pathological examination was used as the gold standard,the results of ultrasound and surgical pathological examination of benign and malignant thyroid nodules were analyzed,and the ultrasound imaging characteristics and hemodynamic parameters of benign and malignant nodules were compared.Results Surgical pathological examination revealed 138 lesions,including 78 benign nodules and 60 malignant nodules.Ultrasound examination showed 76 cases of true negative and 57 cases of true positive.In the diagnosis of benign and malignant thyroid nodules by ultrasound,the sensitivity was 95.00%,the specificity was 97.44%,and the accuracy rate was 96.38%,which is close to the results of surgical pathology.The proportion of malignant nodules with ultrasound imaging features of no calcification,no echo,high echo,clear boundary,rich blood flow signal surrounding and no signal was lower than that of benign nodules,and the proportion of psammoid microcalcification,low echo and rich blood flow signal inside was higher than that of benign nodules,and the differences were statistically significant(P<0.05);there was no significant difference in the proportion of gross calcification between benign and malignant nodules.The peak systolic velocity(PSV)of malignant nodules was faster than that of benign nodules,and the resistance index(RI)was higher than that of benign nodules,and the differences were statistically significant(P<0.05).Conclusion Ultrasound has good application value in the diagnosis of benign and malignant thyroid nodules,which can provide rich pathological information for the differentiation of benign and malignant thyroid nodules,help to improve the diagnostic accuracy,and is worthy of clinical promotion and application.
