摘　　要：目的:探讨乳腺病变的超声、钼靶和增强磁共振检查3种最常用影像学检查方法的诊断效能。方法:收集术前完成乳腺超声、乳腺钼靶和乳腺增强磁共振检查的378个乳腺病灶。对比分析超声、钼靶、增强磁共振检查的准确性、特异性、敏感性、阳性预测值和阴性预测值以及BI-RADS分级后各级的阳性预测值和阴性预测值。采用卡方检验计算P值,P<0.05为具有显著差异。结果:超声、钼靶和增强磁共振的敏感性、特异性和准确性分别为92.81%、89.52%、90.83%,66.67%、58.20%、60.98%和98.55%、78.50%、86.43%。超声和增强磁共振的敏感性、特异性和准确性显著高于钼靶。结论:增强磁共振检查的敏感性最高,超声检查的特异性最高,两者对恶性和良性病灶的诊断各有其优势。而钼靶对恶性病灶的预测具有一定价值。Objective： To investigate the diagnostic efficacy for breast lesions by ultrasound, mammography and enhanced- MR examinations. Methods： We collected 378 breast lesions, all had breast ultrasound, mammography and breast enhanced- MR examinations before surgical excision. The accuracy, specificity, sensitivity, positive predictive value and negative predictive value of each modality were compared. Results： The sensitivity, specificity and accuracy of breast ultrasound, mammography and enhanced-MR examinations was 92.81%, 89.52%, 90.83% and 66.67%, 58.20%, 60.98% and 98.55%, 78.50%, 86.43% respectively. The sensitivity, specificity and accuracy of breast ultrasound and enhanced-MR were higher than mammography. Conclusion： Enhanced-MR had the highest sensitivity, ultrasound had the highest specificity. They both had advantages to diagnose malignant or benign lesions. Also mammography was useful to predict malignant lesions.
