摘要
目的探讨超声弹性成像与二维超声对肝脏良恶性病变的诊断价值,比较两者在肝脏良恶性病变超声诊断中的优势。方法选取2014年8月-2017年10月在宝坻区人民医院就诊的肝脏良性病变180例和肝脏恶性病变129例,均行超声弹性成像与二维超声检查。对相关指标进行测算,如敏感性、特异性、阳性预测值、阴性预测值以及准确度。结果二维超声检查对肝脏恶性病变的灵敏性为0.822、特异性为0.806、阳性预测值为0.752、阴性预测值为0.863、准确度为0.812;超声弹性成像检查对肝脏恶性病变的灵敏性为0.915、特异性为0.950、阳性预测值为0.929、阴性预测值为0.939、准确度为0.935。结论超声弹性成像在肝脏良恶性病变中的诊断价值明显高于二维超声检查。
Objective To evaluate the diagnostic value of ultrasound elastography and two-dimensional ultrasound in benign and malignant liver lesions,and to compare the advantages of the two methods in ultrasound diagnosis of benign and malignant liver lesions. Methods A total of 180 cases of liver benign lesions and 129 cases of liver malignancy were selected from August 2014 to October 2017 in Tianjin Baodi District People's Hospital,and all patients were performed with ultrasound elastography and two-dimensional ultrasonography detection. The related indicators were measured,such as sensitivity,specificity,positive predictive value,negative predictive value,and accuracy. Results The sensitivity of the two dimensional ultrasonography to hepatic malignant lesions was 0.822,the specificity was 0.806,the positive predictive value was 0.752,the negative predictive value was 0.863,and the accuracy was 0.812.The sensitivity of ultrasound elastography to liver malignant lesions was 0.915,specificity of 0.950,positive predictive value of 0.929,negative predictive value of 0.939 and accuracy of 0.935. Conclusion The diagnostic value of ultrasound elastography in benign and malignant liver lesions is significantly higher than that of two-dimensional ultrasound.
