目的 探讨磁共振成像 (MRI)在食管癌中的应用价值。方法 均于 MRI前进行食管钡餐和食管镜检查 ,并取活组织经病理学诊断证实为癌变。 30例均于 MRI1周内经手术治疗 ,8例为开胸探查术。MRI同手术及病理进行对照。结果 T1 加权像对食管癌肿本身及其周邻近器官之间的关系有良好的显示作用。 MRI可以显示隆突下肿大淋巴结 ,对纵隔其他部位和膈下淋巴结的探测帮助不大。结论 MRI能够区别食管壁正常组织和癌组织 ,并有助于判断肿瘤的可切除性。
Objective To investigate the value of magnetic resonance imaging (MRI) in esophageal cancer. Methods All patients underwent esophageal barium meal and esophagoscopy before MRI, and confirmed the pathological diagnosis of cancerous tissue. Thirty patients were surgically treated within 1 week after MRI and 8 patients underwent thoracotomy. MRI with surgery and pathological control. Results T1-weighted images of the esophageal cancer itself and adjacent organs have a good relationship between the display. MRI can show lymph nodes under the bulge, the mediastinal and other parts of the subdiaphragmatic lymph node detection is not helpful. Conclusion MRI can distinguish normal esophageal tissue from cancerous tissue and help to determine the resectability of the tumor.
