目的探讨超声弹性成像技术与常规超声在乳腺结节诊断中的比较。方法选取自2013年6月-2015年6月期间的80例乳腺结节患者,共98个乳腺结节采用超声弹性成像与常规超声成像进行检查,对比两种检查方法的灵敏度、特异度、阳性预测值、阴性预测值及诊断准确率。结果常规超声检查良恶性结节诊断的灵敏度为47.36%、特异度为69.62%、阳性预测值为27.27%、阴性预测值为84.61%及诊断准确率为65.31%明显低于超声弹性成像检查的84.21%、94.94%、80.00%、96.15%、92.85%,差异有统计学意义(P<0.05)。结论超声弹性成像对乳腺结节良恶性能作出及时且有效的诊断,是一种安全、准确率高的检查方法,在临床上对乳腺结节良恶性鉴别诊断具有重要价值。
Objective To investigate the ultrasonic elastography and routine ultrasound in the diagnosis of breast nodules. Methods Eighty patients with breast nodules from June 2013 to June 2015 were enrolled. A total of 98 breast nodules were examined by ultrasound elastography and conventional ultrasound imaging. The sensitivity, specificity, Positive predictive value, negative predictive value and diagnostic accuracy. Results The sensitivity, specificity, positive predictive value and diagnostic accuracy of 47.5%, 69.62%, 27.27%, 84.61%, and 65.31% of the diagnostic accuracy of conventional ultrasonography were significantly lower than those of echocardiography %, 94.94%, 80.00%, 96.15% and 92.85%, respectively. The difference was statistically significant (P <0.05). Conclusion Ultrasound elastography is a safe and accurate method for the diagnosis of benign and malignant breast nodules. It is clinically valuable in the differential diagnosis of benign and malignant breast nodules.
