摘　　要：目的:探究采用弹性成像面积比值鉴别诊断乳腺BI-RADS 4类病变的价值。方法:回顾性分析113例接受超声乳腺检查且诊断为BI-RADS 4类的患者的临床资料,从最大横径切面、最大前后径及上下径切面(分别记为A面、B面、C面)测量肿块大小,以病理结果为对照,绘制受试者工作特征(ROC)曲线对弹性成像面积的诊断效能进行分析。结果:113例患者中共137个乳腺肿块,病理结果显示良性肿块98个分为良性组;显示恶性肿块39个分为恶性组;两组患者弹性成像不同切面面积比值有统计学差异(P<0.05);弹性成像不同切面面积比值诊断乳腺BI-RADS 4类病变,以C面的曲线下面积(AUC)值最高,为0.906,诊断敏感度与特异度分别为84.62%、95.92%,以A面的AUC值最低,为0.824,弹性成像不同切面面积比值ROC曲线两两对比均无统计学差异(P>0.05)。结论:弹性成像面积比值在乳腺BI-RADS 4类病变鉴别中诊断效能佳,具有良好的临床应用价值。Objective:To explore the value of area ratio of elastography in differential diagnosis of BI-RADS 4 breast lesions.Methods:Retrospective analysis of clinical data of 113 patients diagnosed with BI-RADS 4 who underwent ultrasound breast examination.The size of tumor was measured from the maximum transverse diameter section(A),the maximum anterior-posterior diameter section(B)and the maximum suprainferior diameter section(C).The diagnostic efficacy of area ratio of elastography was analyzed using the receiver operating characteristic(ROC)curve,with pathological results as control.Results:A total of 137 breast lumps were found in 113 patients.Pathological results showed that there were 98 benign lumps(benign group)and 39 malignant lumps(malignant group).The area ratios of different sections in elastography showed statistically significant differences between the two groups(P<0.05).In the diagnosis of BI-RADS 4 breast lesions using area ratios of different sections in elastography,the AUC of area ratio of section C was the largest,which was 0.906.Its diagnostic sensitivity and specificity were 84.62%and 95.92%.The AUC of area ratio of section A was the smallest,which was 0.824.Pairwise comparison of the area ratios of different sections in elastography found no significant difference in ROC curves(P>0.05).Conclusion:The area ratio of elastography is efficient in differential diagnosis of BI-RADS 4 breast lesions and has good clinical application value.
