目的:探讨自动乳腺全容积成像(automated breast volume scanner,ABVS)技术与X线钼靶(mammography,MG)对超声乳腺影像和数据报告系统(breast imaging reporting and data system ultrasound,BI-DS-US)4类乳腺小肿块良恶性诊断的应用价...目的:探讨自动乳腺全容积成像(automated breast volume scanner,ABVS)技术与X线钼靶(mammography,MG)对超声乳腺影像和数据报告系统(breast imaging reporting and data system ultrasound,BI-DS-US)4类乳腺小肿块良恶性诊断的应用价值。方法:利用ABVS及MG对常规超声(ultrasound,US)诊断为BI-DS-US 4类的103例患者共109枚小肿块进行扫查,以术后病理结果作为金标准,分析两者与US联合应用的诊断效能。结果:US,US联合MG,US联合ABVS,US与ABVS及MG三者联合诊断的敏感性分别为85.5%,86.8%,94.7%,96.0%;特异性分别为66.7%,69.7%,81.8%,84.9%;准确率分别为79.8%,81.6%,90.8%,92.7%;受试者工作特征(receiver operating characteristic,ROC)曲线的曲线下面积(area under curve,AUC)分别为0.76,0.78,0.88,0.90。US联合ABVS诊断准确率及AUC均高于US及US联合MG(P<0.05),特异性及敏感性差异无统计学意义(P>0.05)。US联合ABVS,US与ABVS及MG三者联合组间比较,其敏感性、特异性、准确性和AUC差异均无统计学意义(P>0.05)。结论:对于BI-DS-US 4类乳腺小肿块,ABVS联合US能提高其诊断效能,且优于US联合MG。展开更多
