摘　　要：目的探讨数字乳腺断层摄影(DBT)与超声弹性成像(UE)联合在乳腺癌诊断中的应用价值。方法回顾性分析本院350例乳腺结节的DBT、UE及MRI影像学资料,与手术病理结果为金标准,比较DBT和UE联合与MRI在诊断敏感度、特异度、阳性预测值、阴性预测值及准确率上的差别。结果 DBT、UE与MRI三者在诊断敏感度、特异度、阳性预测值、阴性预测值及正确率上差别明显(P﹤0.05),将DBT和UE联合后与MRI比较则诊断敏感度、特异度、阳性预测值、阴性预测值及正确率上分别为97.7%vs 98.8%、82.8%vs 74.2%、94.0%vs91.4%、96.3%vs 95.8%、93.7%vs 92.3%,两者差别不大(P﹥0.05)。结论 DBT和UE联合经济、便捷,可靠性高,可有效提高乳腺癌诊断效能。Objective The aim of this study was to explore thediagnostic value ofdigital breast tomosynthesis(DBT)combined with elastography in the breast cancer.Methods 350 patients with breast nodules confirmed by pathology underwent DBT,ultrasound elastography and MRI,the imaging characteristics were analyzed,and the sensitivity,specificity,positive predictive value,negative predictive value and coincidence rate of MRI and digital breast tomosynthesis combined with elastography were compared.Results There were significant statistical differences(P﹤0.05) between the sensitivity,specificity,positive predictive value,negative predictive value and coincidence rates of these three imaging exams,but there was no statistical significance(P﹥0.05) between MRI and digital breast tomosynthesis combined with elastography(97.7% vs 98.8%,82.8% vs 74.2%,94.0% vs 91.4%,96.3% vs 95.8%,93.7% vs 92.3%).Conclusion The combination of digital breast tomosynthesis and elastography was more economical,convenient and feasible,the diagnostic value of breast cancer could be effectively improved.
