甲状腺癌采用超声仪的诊断价值及准确率分析

Diagnostic Value and Accuracy of Ultrasound in Thyroid Cancer

目的:探析甲状腺癌患者采用超声仪诊断的效果及准确率。方法:选取2019年8月~2021年8月收治的96例甲状腺结节患者作为研究对象,所有患者均接受超声仪检查,以病理诊断结果作为金标准,统计超声仪对甲状腺癌的诊断准确率,评估其诊断价值。结果:超声仪诊断甲状腺癌的敏感度为89.71%(61/68),特异度为85.37%(35/41),准确性为88.07%(96/109),阳性预测值为91.04%(61/67),阴性预测值为83.33%(35/42);在接受超声仪检查所得声像图中,良性结节与甲状腺癌血流信号比较差异不大(P>0.05),与良性结节相比,甲状腺癌边界欠清晰,病灶直径更大,内部回声多为低回声,钙化现象更严重,淋巴结增大更明显,两者存在明显差异(P<0.05)。结论:应用超声仪诊断甲状腺癌可获得良好的诊断效能,诊断准确率较高,能够明确甲状腺结节声像特征,从而为临床诊断提供可靠依据。

Objective:To explore the effect and accuracy of ultrasound diagnosis in patients with thyroid cancer.Methods:96 patients with thyroid nodules treated from August 2019 to August 2021 were selected as the research object.All patients were examined by ultrasound.Taking the pathological diagnosis results as the gold standard,the diagnostic accuracy of ultrasound in thyroid cancer was counted and its diagnostic value was evaluated.Results:The sensitivity,specificity and accuracy of ultrasonography in the diagnosis of thyroid cancer were 89.71%(61/68),85.37%(35/41),88.07%(96/109),91.04%(61/67)and 83.33%(35/42);In the ultrasonogram obtained by ultrasonography,there was little difference in blood flow signals between benign nodules and thyroid cancer(P>0.05).Compared with benign nodules,the boundary of thyroid cancer was not clear,the diameter of lesion was larger,the internal echo was mostly low echo,calcification was more serious,and the enlargement of lymph nodes was more obvious(P<0.05).Conclusion:The application of ultrasound in the diagnosis of thyroid cancer can obtain good diagnostic efficiency and high diagnostic accuracy,and can clarify the ultrasonic characteristics of thyroid nodules,so as to provide a reliable basis for clinical diagnosis.
