摘要
目的:探讨BI-BADS分类系统在乳腺X线及超声诊断中的价值。方法:搜集2007年12月-2008年12月均行X线及超声检查、有病理证实或临床随诊1年以上者共1432例患者。年龄23～83岁,均值49.5岁。绝经565例(39.5%),未绝经867例(60.5%)。根据BI-RADS系统对两种检查的结果进行评价。结果:共检出1500个病灶,737个(49.1%)良性病灶,763个(50.9%)恶性病灶。X线BI-RADS 1至5类的恶性百分比分别为12.9%、3.1%、8.9%、70.9%和98.3%;超声分别为3.9%、3.9%、6.3%、62.8%和95.7%。X线、超声BI-RADS分类ROC曲线下的面积分别为0.901和0.945(P=0.000)。X线摄影及超声检查的敏感度分别为90.0%和95.4%,特异度为83.0%和84.8%,准确度为86.6%及90.2%。结论:X线及超声BI-RADS分类系统能很好预测乳腺恶性肿瘤的风险,对于临床有指导价值。
[Abstract] Objective：To investigate the performance of digital mammography （DM） and ultrasonography （US） with BI-RADS categories. Methods： From December 2007 to December 2008,1432 patients suspected of breast carcinoma had DM and US examinations, with pathological confirmation or 1 year follow-up. The patients aged from 23 to 83 years, average 49.5 years. 867 （60.5%） patients were menstruous and the other 565 （39.5%） were menopausal. Both modalities were as sessed according to BI-RADS categories. Results：In 1432 patients, 1500 lesions including 737 benign and 763 malignant were found. The positive predictive value of DM BI-RADS category 1-5 were 12.9%,3. 1%,8.90% ,70.9% and 98.3%,respec tively,and of US were 3.9%,3.9%,6.3% ,62.8% and 95.7%,respectively. The area under ROC of DM and US BI-RADS was 0. 901 and 0. 945, respectively. Conclusion： BI-RADS categories are useful for predicting the presence of malignancy. US has shown better performance than DM for clinical patients.
