摘　　要：目的:探讨动态对比增强(DCE)-磁共振成像(MRI)在肺部良恶性病变鉴别诊断中的应用价值。方法:选取绵阳市中心医院2020年1月至2021年10月期间收治的75例肺部占位性病变患者,对其均进行MRI、DCE-MRI检查,分析DCE-MRI鉴别诊断肺部恶性病变的临床价值,比较良恶性病变DCE-MRI参数的差异。结果:DCE-MRI诊断肺部恶性病变的敏感度、特异度及准确率分别为93.75%、96.30%、94.67%,均高于MRI平扫(68.75%、74.07%、70.67%),差异有统计学意义(P<0.05)。肺部恶性病变的ktrans、Kep、iAUC均高于良性病变,差异有统计学意义(P<0.05)。肺部良恶性病变的Ve相比,差异无统计学意义(P>0.05)。结论:DCE-MRI在肺部良恶性病变鉴别诊断中的应用价值较高。Objective:To investigate the application value of dynamic contrast enhancement(DCE)-magnetic resonance imaging(MRI)in the differential diagnosis of benign and malignant pulmonary lesions.Methods:A total of 75 patients with pulmonary spaceoccupying lesions admitted to Mianyang Central Hospital from January 2020 to October 2021 were selected.MRI and DCE-MRI were performed on all of them.The clinical value of DCE-MRI in differential diagnosis of malignant pulmonary lesions was analyzed,and the difference of DCE-MRI parameters between benign and malignant lesions was compared.Results:The sensitivity,specificity and accuracy of DCE-MRI in the diagnosis of pulmonary malignant lesions were 93.75%,96.30%and 94.67%,respectively,which were higher than those of MRI plain s can(68.75%,74.07%,70.67%),and the differences were statistically significant(P<0.05).The Ktrans,Kep and iAUC of malignant lung lesions were higher than those of benign lung lesions,and the differences were statistically significant(P<0.05).There was no significant difference in Ve between benign and malignant lung lesions(P>0.05).Conclusion:DCE-MRI has a high value in the differential diagnosis of benign and malignan t pulmonary lesions.
