目的探讨乳腺MR影像报告和数 据系统(BI-RADS-MRI)在基层医院的应用 价值，从而提高基层医院乳腺MRI的报告 书写规范及诊断水平。方法 回顾性分析 我院2014年5月至2018年2月行乳腺MRI检 查并做手术的患者的资料，共计201名患 者，共计217处病灶，由2名经验丰富的副 主任医师根据BI-RADS-MRI分类标准阅片 作出BI-RADS-MRI分类，以IV类作为判读 阳性评价的阈值，将BI-RADS-MRI分类结 果与病理结果作对照，并计算BI-RADSMRI分类对病变良恶性判断的敏感性、 特异性、阳性预测值与阴性预测值。结 果 201名患者共计217处病灶的BI-RADSMRI分类对病灶良恶性判断的灵敏度、特 异度、阳性预测值、阴性预测值分别为 99.0%、51.8%、65.0%、98.3%。结论 乳 腺MR影像报告和数据系统(BI-RADS-MRI) 值得在基层医院推广使用。

Objective To explore the application value of MR image report and data system (BI-RADS-MRI) in the primary hospital, to improve the report writing standard and diagnosis level of breast MRI. Methods 201 patients, a total of 217 lesions, were enrolled in the study, from May 2014 to February 2018,who undergone breast MRI examination and surgery. BI-RADS-MRI classification was analyzed by 2 deputy director of the physician according to the classification criteria of BI-RADS-MRI reading, taking IV as positive interpretation evaluation threshold. BI-RADS-MRI classification and pathological results were compared, and sensitivity, specificity, positive predictive value, negative predictive value of the BI-RADS-MRI classification in malignancy judgment was calculated. Results The sensitivity, specificity, positive predictive value and negative predictive value of BI-RADS-MRI classification for 217 lesions in 201 patients were 99%, 51.8%, 65%, 98.3%. Conclusion MR image report and data system (BI-RADSMRI) of the breast should be popularized in the primary hospital.
