摘　　要：目的:通过分析食管癌的影像学表现,并与手术和病理结果对比,明确MRI对食管癌手术可切除性的评估价值。方法:前瞻性分析了20例食管癌的MRI表现及其侵犯主动脉、气管支气管、心包的MRI表现,全部病例均行横断面及斜冠状面成像。结果:5例MRI显示主动脉受侵,其中2例与手术相符,3例手术示肿瘤与主动脉粘连;15例MRI提示主动脉未受累,与手术相符。3例MRI显示支气管受累,其中1例手术证实为受累,2例手术证实为粘连;17例MRI提示气管、支气管未受累,与手术相符。MRI诊断食管癌主动脉受累的敏感度、特异度及诊断符合率分别为100%、83%和85%,诊断气管、支气管受累的敏感度、特异度及诊断符合率分别为100%、89%和85%。结论:MRI能清楚显示食管癌与周围结构的关系,对食管癌手术可切除性的术前评估具有重要价值。Objective：To assess the value of MRI in resectability prediction of esophageal carcinoma. Methods：20 cases of esophageal carcinoma were performed MR scans by T1 WI serieses and T2WI series and enhancement. MR imaging included axial and oblique coronal. Tracheobronchial invasion and aortic invasion were diagnosed. Results： Two patients had been proved unresectable tumors for aortic invasion. Three patients had false positive findings about aortic invasion and the two about tracheobronchial invasion. All patients had no false negative findings. The sensitivity, specificity and accuracy rate of aortic invasion were 100% , 83 % ,85 %, respectively. The sensitivity, specificity and accuracy rate of tracheobronchial invasion were 100% ,89% ,85 %,respectively. Conclusion： It is fine for MR1 to reveal esophageal carcinoma and the relation to adjacent structures. It plays an important role in resectability prediction of esophageal carcinoma.
