摘　　要：目的探讨弥散加权成像(DWI)联合磁共振动态增强(DCE-MRI)技术鉴别乳腺良性病变和乳腺癌的临床价值。方法回顾性分析2015年6月-2017年12月间收治的102例乳腺病变患者临床资料,患者均经DWI、DCE-MRI检查,以病理检查结果为金标准,比较不同检查方式及DWI、DCE-MRI联合检查评估乳腺良恶性病变的准确性和应用价值(灵敏度、特异度、准确率、阳性预测值和阴性预测值)。结果①DWI、DCE-MRI、DWI联合DCE-MRI诊断乳腺良恶性病变的灵敏度、特异度、准确率、阳性预测值和阴性预测值为90.00%、71.88%、84.31%、87.50%、76.67%,91.67%、80.00%、88.24%、91.67%、80.00%,95.71%、84.38%、92.16%、93.06%、90.00%。结论DWI联合DCE-MRI技术鉴别乳腺良性病变和乳腺癌效果良好,有利于提高诊断准确性,临床应用价值可观。Objective To explore the clinical value of diffusion-weighted imaging(DWI)combined with dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI)in the differential diagnosis of benign breast lesions and breast cancer.Methods The clinical data of 102 patients with breast lesions admitted between June 2015 and December 2017 were retrospectively analyzed.All patients were examined by DWI and DCE-MRI.The results of pathological examination were used as the gold standard to compare and evaluate the accuracy and application value(sensitivity,specificity,accuracy,positive predictive value and negative predictive value)of benign and malignant breast lesions by different examination methods and DWI combined with DCE-MRI.Results The sensitivity,specificity,accuracy,positive predictive value and negative predictive value of DWI,DCE-MRI and DWI combined with DCE-MRI in the diagnosis of benign and malignant breast lesions were 90.00%,71.88%,84.31%,87.50%,76.67%,and 91.67%,80.00%,88.24%,91.67%,80.00%,and 95.71%,84.38%,92.16%,93.06%,90.00%.Conclusion DWI combined with DCE-MRI can have good effects in the differential diagnosis of benign breast lesions and breast cancer,and it is helpful to improve the diagnostic accuracy,and has considerable clinical application value.
