常规彩色多普勒超声与弹性成像技术在诊断乳腺肿块中的价值

Conventional ultrasound and elastography in the diagnosis of breast nodules

目的探讨联合应用常规彩色多普勒超声与弹性成像技术在诊断乳腺肿块中的价值。方法对超声检查发现91例患者的98个乳腺肿块进行超声弹性成像与常规彩色多普勒超声检查,以术后病理结果作为金标准,对常规超声诊断,弹性成像诊断及两者联合诊断对乳腺肿块的鉴别价值分别采用SPASS18.0统计软件进行分析,率的比较采用χ2检验,P<0.05为差异有统计学意义。结果诊断乳腺肿块的敏感性、特异性及准确率比较:常规彩色多普勒超声分别为83.9%、68.7%及73.5%;超声弹性成像分别为:83.9%、59.7%及67.3%;而联合应用超声弹性成像与彩色多普勒超声检查诊断乳腺肿块优于前2种,分别为90.3%、91.0%及90.8%,三种检查方式在乳腺良恶性肿块的鉴别诊断中,差异均有统计学意义P<0.01。结论在运用超声诊断乳腺肿块时,联合应用常规彩色多普勒超声与弹性成像技术明显提高了准确率。

Objective To investigate the clinical value of combined application of B mode ultrasound and elastography in the diagnosis of breast nodules. Methods Clinical characteristics of 98 nodules in 91 patients were examined by conventional ultrasound and elastography, with postoperative pathology results as ＂gold standard＂. Comparison was made between the diagnosis of the ultrasound and pathology results by using SPASS 18. 0 software to evaluate clinical value of combined application of conventional ultrasound, and elastography in the differential diagnosis of breast nodules. The test was used in the ratio comparison, and P 〈 0.05 was considered statistically significant. Results The diagnostic sensitivity, specificity and accuracy of breast nodules was 83.9% ,68.7% and 73.5% respectively by using B mode ultrasound, 83.9% ,59.70/0 ,and 67.3% by using elastography. However, these diagnostic indexes were 90. 3%, 91. 0% and 90. 8% respectively by using the combination of B mode ultrasound and elastography. There was significant difference between these three diagnostic performances in the differential diagnosis of benign and malignant breast nodules （ P 〈 0.01 ）. Conclusion The combination of B mode ultrasound and elastography improved the diagnostic accuracy of breast nodules.
