超声弹性及断层成像对甲状腺良恶性病变的诊断价值

目的探究超声弹性及断层成像对甲状腺良恶性病变的诊断价值。方法选择2015年1月至2018年1月本院接受治疗的98例(121个结节)甲状腺结节患者为研究对象,分别对其实施超声弹性成像及计算机断层成像检查,以病理学检测结果为金标准,评估两种单独检测及联合检测对良恶性甲状腺结节评估的敏感度、特异度、准确度并进行对比,同时以病理检查结果为标准,将结节区分为良性组(75个)和恶性组(46个),对比两种结节超声弹性检查时弹性评分及SR值的差异。结果①超声弹性成像对甲状腺结节良恶性鉴别一致性为86.78%,灵敏度为86.96%,特异度为86.67%,阳性预测值为80.00%,阴性预测值为91.55%;②计算机断层成像对甲状腺结节良恶性病变鉴别的一致性为75.21%,灵敏度为67.39%,特异度为80.00%,阳性预测值为67.39%,阴性预测值为80.00%;③联合检测对甲状腺良恶性结节鉴别的一致性为92.56%,灵敏度为93.48%,特异度为92.00%,阳性预测值为80.00%,阴性预测值为91.55%;④对比发现联合检测鉴别的一致性、灵敏度、特异度均高于两种单独检测方式;⑤分析显示恶性病变结节弹性评分及SR值均明显高于良性结节(P<0.05)。结论相比于计算机断层成像,超声弹性成像对甲状腺结节良恶性病变具有更好的鉴别价值,同时弹性评分及SR值可作为评估甲状腺结节良恶性病变指标,但仍建议联合应用超声弹性成像及计算机断层成像技术实施鉴别。

Diagnostic value of ultrasound elastography and tomography in benign and malignant thyroid lesions

Objective To investigate the diagnostic value of ultrasound elasticity and tomography for benign and malignant thyroid lesions.Methods 98 patients(121 nodules)with thyroid nodules who were treated in our hospital from Jan.2015 to Jan.2018 were enrolled in the study.Ultrasound elastography and computed tomography were performed respectively.The pathological test results were used as the gold standard.To evaluate the sensitivity,specificity and accuracy of two separate and combined tests for the assessment of benign and malignant thyroid nodules.In contrast,the results of pathological examination was used as the standard,and the nodules were divided into benign group(75)and malignant group(46).The differences in elasticity score and SR value between the two nodules were compared.Results①The consistency of ultrasound elastography for the differentiation of benign and malignant thyroid nodules was 86.78%,the sensitivity was 86.96%,the specificity was 86.67%,the negative predictive value was 91.55%,and the positive predictive value was 80.00%.②The consistency of computed tomography in the differential diagnosis of benign and malignant thyroid nodules was 75.21%,the sensitivity was 67.39%,the specificity was 80.00%,the negative predictive value was 80.00%,and the positive predictive value was 67.39%.③The consistency of the joint detection for the differentiation of benign and malignant thyroid nodules was 92.56%,the sensitivity was 93.48%,the specificity was 92.00%,the positive predictive value was 80.00%,and the negative predictive value was 91.55%.④The consistency,sensitivity and specificity of the combined detection were higher than the two separate detection methods.⑤The analysis showed that the malignant lesions nodule elasticity score and the SR scores were significantly higher than the benign nodules(P<0.05).Conclusion Compared with computed tomography,ultrasound elastography has a better value in the differential diagnosis of benign and malignant thyroid nodules.At the same time,the elasticity score and SR value can be used as indicators to evaluate benign and malignant lesions of thyroid nodules.However,it is still recommended to use ultrasound elastography together.Computerized tomography technology is used to identify.
