摘　　要：目的:探讨基于灰阶超声图像纹理分析在乳腺影像报告和数据系统(BI-RADS)3类或4a类乳腺小结节定性诊断中的应用价值。方法:选取首次发现的乳腺小结节(最大直径≤20 mm)、常规超声诊断为BIRADS 3类或4a类的患者225例,将良恶性病例分为测试集和验证集,分别进行灰阶超声影像纹理分析并对比。结果:对于乳腺小结节,正态判别分析-FPM的误判率最低,测试集误判率为13.3%,验证集误判率为13.4%。Logistic回归分析结果表明,WavEnLH_s-3及Sigma为区分BI-RADS 3类或4a类乳腺小结节良恶性的独立影响因子。结论:基于灰阶超声图像纹理分析的线性判别分析/正态判别分析或Logistic回归分析对BI-RADS 3类或4a类乳腺小结节均有较好的定性诊断价值,可为临床诊治提供较为客观的参考。Objective:To explore the application value of grayscale ultrasound image texture analysis in the qualitative diagnosis of breast small nodules categorized as BI-RADS 3 or 4a.Methods:A total of 225 patients with newly detected breast small nodules(maximum diameter≤20 mm)and diagnosed as BI-RADS 3 or 4a by conventional ultrasound were enrolled.Benign and malignant cases were divided into a test set and a validation set.Grayscale ultrasound image texture analysis was performed and compared between the two sets.Results:For breast small nodules,the Normal Discriminant Analysis-FPM(NDA-FPM)model demonstrated the lowest misclassification rate,with 13.3%in the test set and 13.4%in the validation set.Logistic regression analysis revealed that WavEnLH_s-3 and Sigma were independent influencing factors for distinguishing benign and malignant BI-RADS 3 or 4a breast small nodules.Conclusion:Linear discriminant analysis/normal discriminant analysis or logistic regression models based on grayscale ultrasound image texture analysis exhibit significant value in the qualitative diagnosis of breast BI-RADS 3 or 4a small nodules,providing an objective reference for clinical decision-making.
