摘要

目的：

探讨超声造影灌注峰值强度在乳腺癌术前诊断中的应用价值及稳定性。

方法：

通过3名观察者分别对151例乳腺肿块的超声造影灌注强度进行定量分析，分析每一名观察者所得灌注峰值强度在良恶性肿块间的差异有无统计学意义，并通过3名观察者间组内相关系数（intraclass correlation coefficient，ICC）比较其稳定性。

结果：

3名观察者所测得良性组峰值强度均值分别为34.97、26.32和24.38，恶性组峰值强度均值分别为23.43、17.23和17.23，3名观察者所得良恶性肿块灌注峰值强度的组间差异均有统计学意义（

0.001）。恶性肿块的均值明显较良性肿块低。3名观察者间ICC=0.754（95%CI：0.693~0.807，

0.001）。

结论：

超声造影灌注峰值强度有助于乳腺癌的术前诊断，且不同观察者间信度良好，值得进一步深入研究。

Abstract

Objective:

To investigate the application value and stability of peak intensity of contrastenhanced ultrasound in preoperative diagnosis of breast cancer.

Methods:

The peak intensity of contrast-enhanced ultrasound of 151 breast masses were quantitatively analyzed by three observers. Whether peak intensity had statistically difference between benign and malignant tumors was investigated. The intraclass correlation coefficient (ICC) between three observers was compared for the stability.

Results:

The mean peak values in the benign group measured by three ob

servers were 34.97

26.32

24.38

and the mean peak values in the malignant group were 23.43

17.23

and 17.23

respectively. All P value for the peak intensity between benign and malignant tumors were

0.001 by three observers

and the peak intensity had statistically significant difference. The mean peak value of malignant tumors was significantly lower than that of benign tumors. ICC among three observers was 0.754 (95%CI: 0.693-0.807

0.001).

Conclusion:

Peak intensity of contrast-enhanced ultrasound contributes to the preoperative diagnosis of breast cancer

and the inter-observer reliability is good and worth of further study.
