超声弹性成像技术与二维灰阶+CDFI超声诊断乳腺疾病对照研究

Comparative study of ultrasonic elsatography with two-dimensional gray scale +CDFI ultrasound in diagnosing of breast diseases

目的探讨超声弹性成像与二维灰阶+CDFI超声在诊断乳腺疾病中的价值。方法以手术病理为诊断标准,对比分析超声弹性成像与二维灰阶+CDFI超声诊断乳腺疾病的准确性。结果超声弹性成像诊断乳腺恶性病变的敏感性、特异性和准确性分别为83%、98%、95%。二维灰阶+CDFI超声诊断乳腺恶性病变的敏感性、特异性和准确性分别为82%、78%、79%。结论超声弹性成像诊断乳腺病变的准确性高于二维灰阶+CDFI超声,但两者结合可望提高乳腺良恶性病变诊断的准确性。

Objective To investigate the value of ultrasonic elastography and two-dimensional gray scale ＋CDFI ultrasound in diagnosing breast diseases.Methods To compare the accuracy of ultrasonic elastography and two-dimensional gray scale ＋CDFI ultrasound for diagnosing breast diseases using pathology as the golden criteria.Results The sensitivity,specificity,accuracy of ultrasonic elastography were 83%,98%,95%,and those of two-dimensional gray scale ultrasound were 83%,78%,79% respectively.Conclusion The accuracy of ultrasonic elastography is much higher than that of two-dimensional gray scale＋CDFI ultrasound.The combination of the two methods can elevate the accuracy for differentiating the benign and malignant breast tumors.
