超声征象评分系统对乳腺实性结节分类诊断的研究

The study of classification for breast solid nodular lesions using an ultrasonographic characteristic diagnostic score system

目的探讨超声征象评分系统对乳腺实性结节分类诊断的可靠性。方法分析205个乳腺实性结节的超声征象，建立超声征象评分系统，根据病变的评分值将其分类；用ROC曲线评价该评分系统的诊断价值。结果超声征象评分系统分类诊断的ROC曲线下面积为0．977，诊断的敏感性、特异性分别为92．0％、92．3％。结论应用超声征象评分系统对乳腺实性结节进行分类诊断可以提高诊断的准确率。

Objective To study the accuracy of an ultrasonographic characteristic diagnostic score system（UCDSS） which was used to classify the breast solid nodular lesions. Methods UCDSS were established by analyzing the ultrasonographic sign of the 205 breast solid nodular lesions. These lesions were classified according to the total scores of each ultrasonographic sign. ROC curve was used to evaluate the value of UCDSS. Results The area under ROC curve of UCDSS was 0. 977, the sensitivity and specificity was 92.0%, 92.3 % respectively. Conclusions The classification based on the UCDSS may increase the diagnostic accuracy of the differentiation between benign and malignant breast solid nodular lesions.
