摘　　要：目的探讨电子计算机断层扫描(CT)和磁共振成像(MRI)在十二指肠乳头癌上的诊断价值。方法选取我院2014年5月至2021年5月CT及MRI诊为十二指肠占位且经手术病理证实为十二指肠乳头癌的78例患者为研究对象,分析其CT和MRI检查的影像资料,比较两种检查方式的诊断效果。结果CT检查十二指肠乳头癌36例,与手术病理结果对照,CT诊断的准确率为75%(36/48),AUC值为0.713,敏感度为62.50%,特异度为80.00%。MRI检查十二指肠乳头癌42例,与手术病理结果对照,MRI诊断的准确率为87.50%(42/48),AUC值为0.829,敏感度为79.17%,特异度为86.67%。MRI检查的AUC值显著高于CT检查(P<0.05)。结论CT和MRI检查可以通过多种直接和间接征象来鉴别十二指肠乳头癌,在十二指肠乳头癌上诊断均有一定的价值,其中多序列MRI检查在一定程度上优于CT检查。Objective To investigate the diagnostic value of computerized tomography(CT)and magnetic resonance imaging(MRI)in duodenal papillary carcinoma.Methods From May 2014 to May 2021,78 patients with space occupying duodenum diagnosed by CT and MRI and confirmed by surgery and pathology as duodenal papillary carcinoma in our hospital were selected as the study objects,and the imaging data of CT and MRI examinations were analyzed to compare the diagnostic effects of the two examination methods.Results CT diagnosed 36 cases of duodenal papillary carcinoma.Compared with surgical pathological results,the diagnostic accuracy,AUC,sensitivity and specificity of CT were 75%(36/48),0.713,62.50%,and 80.00%,respectively.MRI diagnosed 42 cases of duodenal papillary carcinoma.Compared with surgical pathological results,the diagnostic accuracy,AUC,sensitivity and specificity of MRI were 87.50%(42/48),0.829,79.17%,and 86.67%,respectively.The AUC value of MRI was significantly higher than that of CT(P<0.05).Conclusion Both CT and MRI can identify duodenal papillary carcinoma through a variety of direct and indirect signs,and multi-sequence MRI is better than CT to a certain extent.
