摘　　要：目的:分析并比较数字乳腺三维断层摄影(DBT)和磁共振成像(MRI)检查在诊断致密型乳腺疾病中的应用价值。方法:选择在江苏大学附属医院进行检查的108例致密型乳腺疾病患者作为研究对象。对这些患者均进行DBT和MRI检查,分析获得的成像图片,并以组织病理学诊断结果为依据,统计DBT和MRI检查诊断致密型乳腺疾病的灵敏度、特异度、准确度、阳性预测值、阴性预测值、AUC值,并评估乳腺的BI-RADS分级情况。结果:通过对组织病理学资料进行分析显示,在108例致密型乳腺疾病患者中,乳腺恶性病变患者共有65例(占60.19%),乳腺良性病变患者共有43例(占39.81%)。DBT检查诊断乳腺良性病变、恶性病变的正确率分别是55.81%、58.46%,MRI检查诊断乳腺良性病变、恶性病变的正确率分别是74.42%、86.15%(P<0.05)。MRI检查诊断致密型乳腺疾病的灵敏度、准确度、阴性预测值、AUC值均明显高于DBT检查(P<0.05);两种检查方法的诊断特异度、阳性预测值比较(P>0.05)。在致密型乳腺疾病的乳腺BI-RADS分级评估中,MRI检查的4~5级检出率显著高于DBT检查(P<0.05)。结论:在致密型乳腺疾病的影像学诊断中,MRI检查的诊断价值显著高于DBT检查,为今后临床上更好地诊治该病提供了参考依据。Objective:To analyze and compare the application value of digital three-dimensional breast tomography(DBT)and magnetic resonance imaging(MRI)in the diagnosis of dense breast diseases.Methods:108 patients with dense breast disease who were examined in Affiliated Hospital of Jiangsu University were selected as subjects.DBT and MRI examinations were performed on all these patients.The imaging images obtained were analyzed,and the sensitivity,specificity,accuracy,positive predictive value,negative predictive value and AUC value of DBT and MRI in the diagnosis of dense breast diseases were counted based on the histopathological diagnosis results,and the BI-RADS grading of breast was evaluated.Results:Analysis of histopathological data showed that in 108 patients with dense breast diseases,there were 65 patients with malignant breast lesions(60.19%)and 43 patients with benign breast lesions(39.81%).The correct rates of DBT diagnosis of benign and malignant breast lesions were 55.81%and 58.46%,respectively,while the correct rates of MRI diagnosis of benign and malignant breast lesions were 74.42%and 86.15%,respectively(P<0.05).The sensitivity,accuracy,negative predictive value and AUC value of MRI in the diagnosis of dense breast diseases were significantly higher than those of DBT(P<0.05).The diagnostic specificity and positive predictive value of the two methods were compared(P>0.05).In the breast BI-RADS grading evaluation of dense breast diseases,the detection rate of grade 4 to 5 by MRI was significantly higher than that by DBT(P<0.05).Conclusion:In the imaging diagnosis of dense breast diseases,the diagnostic value of MRI examination is significantly higher than that of DBT examination,which provides a reference for better diagnosis and treatment of this disease in the future clinic.
