摘要
目的：探讨在不同切面中应用超声弹性成像面积比值法对BI-RADS 4级乳腺肿块良恶性判断的价值。方法：对97例患者共116个BI-RADS 4级乳腺肿块分别进行肿块横径最大切面（A切面）、纵横比最大切面（B切面）、感兴趣部位最大面积切面（C切面）弹性成像检查，对弹性成像图像进行面积比值法分析。以病理诊断为金标准，绘制受试者工作特征曲线，判断三个不同切面对BI-RADS 4级乳腺肿块的诊断价值。结果：A、B、C三个切面BI-RADS 4级乳腺肿块良、恶性组间面积比值差异均具有统计学意义。三个切面所构建ROC曲线间比较差异无统计学意义。A切面面积比值以1.33为临界点判断肿块良恶性的敏感性、特异性、准确性分别为75.8%、95.2%、89.7%；B切面面积比值以1.25为临界点判断肿块良恶性的敏感性、特异性、准确性分别为84.8%、85.5%、85.3%；C切面面积比值以1.55为临界点判断肿块良恶性的敏感性、特异性、准确性分别为81.8%、95.2%、91.4%。结论：A、B、C三个不同切面超声弹性成像面积比值均有助于提高BI-RADS 4级乳腺肿块良恶性鉴别诊断。
Abstract
Objective: To explore the diagnostic value of area ratio on ultrasonographic elastography with different planes in differentiating benign from malignant BI-RADS 4 breast tumors. Methods: Ninety-seven patients with 116 BI-RADS 4 breast tumors were examined by ultrasonographic elastography with the plane of the maximum diameter(plane A), the plane of maximum aspect ratio(plane B) and the maximum area plane of interest(plane C). The ultrasonographic elastography images were analyzed in area ratio method. The pathologic diagnosis was the gold standard. The diagnostic value of the 3 planes was evaluated with receiver operating characteristic(ROC) curve. Results: The area ratios of benign and malignant BI-RADS 4 breast tumors were significantly different in plane A, B and C. The ROC curve of the three planes showed no significant difference. The cut-off point of area was 1.33 by ROC cure in plane A. The sensitivity, specificity and accuracy of area ratio in plane A were 75.8%, 95.2% and 89.7%, respectively. The cut-off point of area was 1.25 by ROC cure in plane B. The sensitivity, specificity and accuracy of area ratio in plane B were 84.8%, 85.5% and 85.3%, respectively. The cut-off point of area was 1.55 by ROC cure in plane C. The sensitivity, specificity and accuracy of area ratio in plane C were 81.8%, 95.2% and 91.4%, respectively. Conclusion: Area ratio on ultrasonographic elastography image with different planes can help to differentiate benign from malignant BI-RADS 4 breast tumors.
