摘　　要：目的 探讨MRI对十二指肠乳头腺癌患者术前TNM分期的临床应用价值。方法 选取本院经手术病理证实为十二指肠乳头腺癌的48例患者术前进行TNM分期,并与术后病理结果相对照。结果 48例十二指肠乳头腺癌患者,MRI对肿瘤浸润深度T分期的总体诊断准确率为83.3%;对淋巴结转移情况N分期的总体诊断准确率为81.3%;对远处转移M分期的总体诊断准确率为95.8%。MRI对十二指肠乳头腺癌术前T、N分期与术后病理分期一致性较好(K=0.731,K=0.650),MRI对M分期与术后病理分期一致性很好(K=0.850)。结论 MRI检查可以较准确的判断肿瘤的浸润深度、淋巴结转移及远处转移情况,对于十二指肠乳头腺癌术前TNM分期具有一定优势。Objective To investigate the clinical value of TNM staging of duodenal papillary adenocarcinoma with MRI. Methods TNM stages of 48 patients with duodenal papillary adenocarcinomaconfirmed by psthology from January 2018 to January 2021 were studied with 3.0 T MRI, and compared with the pathological staging. The consistency of result was analysed with Kappa testing. Results In comparison with pathological results, the accuracy of MRI for T stage was 83.3%, for N stage was 81.3% and for M stage was 95.8% respectively. The T and N stages results of MRI and pathology were consisent well(Kappa=0.731, Kappa=0.656), and M stage result of MRI and pathology were consisent very well(Kappa=0.850). Conclusion MRI can accurately assess the depath of tumor infiltration, lymph node metastasis and distant metastasis, and has certain advantages in evaluating TNM stage of duodenal papillary adenocarcinoma before operation.
