摘　　要：目的:探讨磁共振成像(Magnetic resonance imaging,MRI)、MRI弥散加权成像(Diffusion weighted imaging,DWI)、动态增强磁共振成像(Dynamic contrast-enhanced MRI,DCE-MRI)检查用于诊断子宫内膜癌的价值。方法:选取2021年1月-2023年12月期间于本院就诊的80例高度疑似子宫内膜癌患者作为研究对象。患者均接受MRI、DWI及DCE-MRI检查,并接受子宫内膜活检,以子宫内膜活检结果作为金标准,比较MRI、DWI及DCE-MRI单独及联合对子宫内膜癌的诊断价值。结果:80例高度疑似子宫内膜癌患者经子宫内膜活检确诊65例子宫内膜癌,占81.25%。以子宫内膜活检为金标准,MRI对子宫内膜癌的检出率为63.07%(41/65),DWI对子宫内膜癌的检出率为80.00%(52/65),DCE-MRI对子宫内膜癌的检出率为72.31%(47/65),联合检查对子宫内膜癌的检出率为93.85%(61/65),联合检查的检出率高于各检查单独应用,且与金标准的一致性也高于各检查单独应用;联合检查对子宫内膜癌诊断的敏感度、准确率均高于各检查单独诊断,且联合检查诊断的阴性预测值均显著高于MRI、DCE-MRI单独检查(P<0.05)。结论:MRI、DWI及DCE-MRI联合检查对子宫内膜癌的诊断准确率高于单独检查,且与金标准有较好的一致性。Objective:Magnetic resonance imaging(MRI)and Diffusion weighted imaging(DWI)were discussed.The value of DWI and Dynamic contrast-enhanced MRI(DCE-MRI)in the diagnosis of endometrial cancer.Methods:80 patients with highly suspected endometrial cancer who were admitted to our hospital from January 2021 to December 2023 were selected as the study objects.All patients underwent MRI,DWI and DCE-MRI,and underwent endometrial biopsy.The results of endometrial biopsy were used as the gold standard to compare the diagnostic value of MRI,DWI and DCE-MRI alone and in combination with endometrial cancer.Results:In 80 patients with highly suspected endometrial carcinoma,65 cases(81.25%)were confirmed by endometrial biopsy.Using endometrial biopsy as the gold standard,the detection rate of endometrial cancer by MRI was 63.07%(41/65),that by DWI was 80.00%(52/65),and that by DCE-MRI was 72.31%(47/65).The detection rate of combined examination for endometrial cancer was 93.85%(61/65),and the detection rate of combined examination was higher than that of single examination,and the consistency with the gold standard was also higher than that of single examination.The sensitivity and accuracy of combined examination for the diagnosis of endometrial cancer were higher than that of each examination alone,and the negative predictive value of combined examination was significantly higher than that of MRI and DCE-MRI alone(P<0.05).Conclusion:The diagnostic accuracy of MRI,DWI and DCE-MRI combined examination is higher than that of single examination,and it is in good agreement with the gold standard.
