【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。更多还原

【Abstract】 Objective:To assess the value of MRI in resectability prediction of esophageal carcinoma.Methods:20 cases of esophageal carcinoma were performed MR scans by T₁WI 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 MRI to reveal esophageal carcinoma and the relation to adjacent structures.It plays an important role in resectability prediction of esophageal carcinoma.更多还原
