摘　　要：目的探讨高场磁共振成像（MRI）（starVIBE＋BLADE）在可切除性食管癌术前T分期中的价值。方法前瞻性连续收集2015年4月至2016年3月郑州大学附属肿瘤医院临床及活检病理证实为食管癌的66例患者的高场MRI检查资料。其中男48例、女18例，平均（62±7）岁。由两位具有5年以上胸部MR诊断经验的阅片者，根据食管癌AJCCTNM分期标准，对图像分别进行术前MRI的T分期，并对食管癌MRI的术前T分期结果与术后病理T分期结果进行对照分析。结果两位阅片者术前MRI分期与术后病理T分期一致性很好，两位阅片者对T分期各期评价均获得很高的敏感度、特异度及诊断符合率。结论高场MRI在食管癌术前T分期诊断方面具有很高的准确性，对于T1、T2及T3的诊断准确率优于T4a的诊断，高场MRI可以作为可切除性食管癌术前T分期无创的影像学检查方法。ObjectiveTo explore the value of 3.0 T MRI using multiple sequences （star VIBE＋ BLADE） in evaluating the preoperative T staging for potentially resectable esophageal cancer （EC）. MethodsBetween April 2015 and March 2016, a total of 66 consecutive patients with endoscopically proven resectable EC underwent 3.0T MRI in the Affiliated Cancer Hospital of Zhengzhou University.Two independent readers were assigned a T staging on MRI according to the 7th edition of UICC-AJCC TNM Classification, the results of preoperative T staging were compared and analyzed with post-operative pathologic confirmation. ResultsThe MRI T staging of two readers were highly consistent with histopathological findings, and the sensitivity, specificity and accuracy of preoperative T staging MR imaging were also very high. Conclusion3.0 T MRI using multiple sequences is with high accuracy for patients of potentially resectable EC in T staging. The staging accuracy of T1, T2 and T3 is better than that of T4a. 3.0T MRI using multiple sequences could be used as a noninvasive imaging method for pre-operative T staging of EC.
