摘　　要：目的:探讨MRI对Vater壶腹癌术前T分期的诊断价值,并评估肿瘤的可切除性。方法:回顾性分析Vater壶腹癌患者62例,根据MRI平扫及增强扫描图像确定肿瘤的T分期。结果:MRI T分期与病理分期的一致性较高(K=0.763)。不同MRI T分期的肿瘤最大径及病理分化程度差异均有统计学意义(均P<0.05)。结论:Vater壶腹癌的MRI T分期与病理分期有较高的一致性,能够评估肿瘤的可切除性,并指导临床术式的选择。Objective:To explore the diagnostic value of MRI in preoperative T stages in cancer of the ampulla of Vater and to evaluate the resectability of the tumor.Methods:A retrospective analysis was performed on 62 patients with cancer of the ampulla of Vater.The T stages of the tumor were determined according to the characteristics of the MRI plain scan and enhanced scan.Results:There was a high consistency T-stages in cancer of the ampulla of Vater by MRI and pathology(K=0.763).There were significant differences in tumor maximum diameter and pathological differentiation at different T stages by MRI(P<0.05).Conclusions:MRI can provide a more accurate T-staging for cancer of the ampulla of Vater,evaluate tumor resectability and guide the selection of clinical surgical procedures.
