51例食管癌作了MRI检查。对其中手术的14例进行了MRI与手术及病理的对照观察。MRI分辨率高并能够多方向扫描，因而能显示肿瘤的大小、范围，有无外侵及有无淋巴结转移。对估计癌瘤能否手术切除有重要作用。肿瘤侵及气管支气管，侵及主动脉；或侵及心包为不能切除的指征。本组诊断气道受侵的符合率及主动脉受侵的符合率均为92．8％。因此食管癌术前行MRI检查十分重要，可减少不必要的开胸探查。15例食管癌手术后作了MRI随诊，其中14例有阳性发现，最多见的为纵隔淋巴结转移，其次为吻合口区复发，残段食管癌、肋骨及肺转移。术后MRI随诊可及早发现复发及转移，以使病人能得到及时的治疗。
MRI was performed in 51 cases of esophageal cancer. Of the 14 patients undergoing surgery, MRI was compared with surgery and pathology. MRI has high resolution and can scan in multiple directions, so it can display the size and range of the tumor, with or without external invasion and lymph node metastasis. It is important to estimate whether the cancer can be surgically removed. Tumors invade the trachea and bronchus and invade the aorta; or invading the pericardium are indications of unresectable. The coincidence rate of diagnosis of airway invasion and aortic invasion in this group was 92.8%. Therefore, preoperative MRI examination of esophageal cancer is very important, which can reduce unnecessary exploration of thoracotomy. Fifteen cases of esophageal cancer were followed up by MRI. Among them, 14 cases had positive findings. Mediastinal lymph node metastasis was the most common, followed by anastomotic recurrence, residual esophageal cancer, ribs, and lung metastases. Postoperative MRI follow-up can be found early recurrence and metastasis, so that patients can receive timely treatment.
