摘　　要：目的比较全数字化乳腺X线摄影(FFDM)与数字化乳腺断层融合技术(DBT)在ACR-C类乳腺良恶性病变诊断中的实际应用效果。方法选取108例乳腺病变患者,同时给予FFDM及DBT技术摄影,依据乳房成像报告和数据系统(BI-RADS)评分,对照病理结果评估FFDM、DBT的诊断效能。结果FFDM诊断乳腺良恶性病变的灵敏度、特异度、阳性预测值、阴性预测值和准确度分别为53.85%、90.24%、63.64%、86.05%、81.48%,DBT诊断乳腺良恶性病变的灵敏度、特异度、阳性预测值、阴性预测值和准确度分别为84.61%、95.12%、84.61%、95.12%、92.59%。两种方法的灵敏度比较,差异有统计学意义(Z=-8.55,P<0.05),而特异度无明显差异(Z=-0.71,P>0.05)。DBT对乳腺肿块检出及清晰、遮蔽征象显示明显优于FFDM检测,差异均有统计学意义(χ^(2)分别=4.38、25.34、10.46,P均<0.05)。结论DBT对ACR-C类乳腺良性及恶性病变的诊断效能较FFDM明显提高。Objective To compare the actual application effects of full digital mammography(FFDM)and digital breast tomosynthesis(DBT)in the diagnosis of benign and malignant breast lesions of ACR-C class.Methods Totally 108 patients with breast lesions were selected.They were all received FFDM and DBT examination.The diagnostic efficacy of FFDM and DBT was evaluated refer to the pathological results according to the Breast Imaging Reporting and Data System(BI-RADS)score.Results The sensitivity,specificity,positive predictive value,negative predictive value,and accuracy of DBT in the diagnosis of benign and malignant breast lesions was 84.61%,95.12%,84.61%,95.12%,and 92.59%,which were better than those of FFDM(53.85%,90.24%,63.64%,86.05%,81.48%).The sensitivity between the two methods showed a statistically significant difference(Z=-8.55,P<0.05),while there was no significant difference in specificity(Z=-0.71,P>0.05).DBT was significantly better than FFDM in detecting breast masses and displaying clear and obscured signs,with statistically significant differences(χ^(2)=4.38,25.34,10.46,P<0.05).Conclusion The diagnostic efficacy of DBT for benign and malignant breast lesions of ACR-C class is significantly improved compared to FFDM.
