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 analyze the imaging findings of esophageal cancer and compare it with the results of surgery and pathology to determine the value of MRI in evaluating the resectability of esophageal cancer. Methods: MRI findings of 20 cases of esophageal cancer were analyzed prospectively. MRI findings of aorta, tracheobronchial and pericardium were analyzed prospectively. All the cases were performed transverse and oblique coronal plane imaging. Results: MRI showed aortic invasion in 5 cases, of which 2 cases were consistent with surgery, 3 cases showed tumor and aorta adhesion, 15 cases showed aortic involvement without MRI, which was consistent with surgery. Bronchus involvement was found in 3 cases of MRI, of which 1 case was proved to be involved and 2 cases proved to be adhesions. 17 cases of MRI showed tracheal and bronchial involvement, which was consistent with the operation. The sensitivity, specificity and diagnostic coincidence rate of MRI in diagnosis of aortic involvement of esophageal cancer were 100%, 83% and 85% respectively. The sensitivity, specificity and diagnostic coincidence rate of tracheal and bronchial involvement were 100%, 89% And 85%. Conclusion: MRI can clearly show the relationship between esophageal cancer and the surrounding structures, and it is of great value in the preoperative evaluation of resectability of esophageal cancer.
