超声弹性成像及硬环征、直方图分析鉴别乳腺肿块良恶性的诊断价值

目的：本研究旨在比较弹性成像、弹性成像联合“硬环征”、弹性成像直方图分析的诊断价值。方法：选取2017年1月至2019年1月间于陆军军医大学第二附属医院普通外科就诊的共59个乳房肿块构成本研究组。启动弹性成像功能采集数据,然后在弹性成像图上调节阈值显示硬环征,之后勾选直方图分析。结果：直方图分析的诊断性能(AUC=0.93)优于弹性成像联合“硬环征”(AUC= 0.87)和弹性成像(AUC=0.81)。结论：超声弹性成像直方图分析方法有助于乳腺良、恶性病变的分类,“硬环征”也可提高弹性成像的准确性,有助于提高医师鉴别乳腺肿块良恶性的能力。

Preliminary Study on the Histogram Analysis of Benign and Malignant Breast Masses by Ultrasonic Shear Wave Elastic Imaging

Objective: This study aimed to compare the diagnostic value of elastography, elastography combined with "stiff rim sign" and elastography histogram analysis. METHODS: A total of 59 breast lumps from the general surgery department of the Second Affiliated Hospital of the Army Military Medical University from January 2017 to January 2019 were selected to form this study group. Started the elastography function to collect the data, then adjusted the threshold on the elastography map to display the stiff rim sign, then started the histogram analysis. Results: The diagnostic performance of the histogram analysis (AUC = 0.93) was superior to the elastic imaging combined with "stiff rim sign" (AUC = 0.87) and elastography (AUC = 0.81). Conclusion: Ultrasound elastography histogram analysis method is helpful for the classification of benign and malignant breast lesions. The "stiff rim sign" can also improve the accuracy of elastography and help to improve the ability of physicians to identify benign and malignant breast masses.
