The diagnostic value of ultrasound elastography in breast tumor and analyze the significance of joint DWI / 重庆医学

ABSTRACT

Objective To evaluate the value of ultrasound elastography in the diagnosis of breast tumor ,and compared with imaging analysis .Methods To collect the image data of 160 patients ,confirmed by pathology ,a total of 182 ,preoperative ultra-sound elasticity imaging and DWI ,ultra sonic elastography diagnosis by five points method ,DWI on the basis of the measured ADC value in the diagnosis of lesions ,respectively compared with pathology .Results Ultrasound elastography diagnosis of 89 malignant tumors ,of which the correct diagnosis of 78 malignant tumors ,7 misdiagnosis ,11 benign misdiagnosed as malignant diagnosis;93 benign tumors ,86 of correct diagnosis ,11 misdiagnosis ,7 malignant misdiagnosed as benign ,sensitivity was 87 .6% ,specificity of 92 .5% ,the Accuracy was 93 .9% ;ultrasound elastography and DWI combined imaging diagnosis of 86 malignant tumors ,81 correct diagnosis of malignant tumors ,4 misdiagnosis ,5 from the benign misdiagnosed as malignant diagnosis ,96 benign tumors ,92 correct diagnosis ,5 misdiagnosis ,the sensitivity was 94 .1% ,specificity of 95 .8% ,the accuracy was 97 .2% .Conclusion Ultrasound elas-tography in breast benign and malignant tumor diagnosis with higher sensitivity and specificity ,accuracy ,joint DWI can significantly improve the sensitivity and specificity of breast benign and malignant tumor diagnosis ,accuracy .
