To 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). Between 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. The 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. 3.0 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.
探讨3.0T磁共振成像（MRI）多序列（星状容积内插屏气检查法+刀锋技术）在评估可切除食管癌（EC）术前T分期中的价值。2015年4月至2016年3月，郑州大学附属肿瘤医院对66例经内镜证实可切除的EC患者连续进行3.0T MRI检查。两名独立阅片者根据UICC-AJCC TNM分类第7版对MRI进行T分期，将术前T分期结果与术后病理证实结果进行比较分析。两名阅片者的MRI T分期与组织病理学结果高度一致，术前T分期MR成像的敏感性、特异性和准确性也非常高。多序列3.0T MRI对可切除EC患者的T分期具有较高准确性。T1、T2和T3期的分期准确性优于T4a期。多序列3.0T MRI可作为EC术前T分期的无创成像方法。
