摘　　要：探讨低场MRI诊断肺癌的方法及价值。方法:收集65例经临床及病理确诊的肺癌病例,行低场(0.16T)MRI检查,15例T_1WI加心电门控。结果:非门控短TE序列效果较好。低场MRI对某些发生J特殊部位的肺癌,如肺尖、肺边缘、膈肌附近的肿块显示良好,可判断肺癌侵犯纵隔、心包、血管;鉴别中央型肺癌与其继发改变;确定Pancost's瘤的侵犯范围较为清晰。对纵隔、肺门淋巴结肿大及胸壁侵犯显示非常满意。结论:低场MRI同样适用于了解肺癌有无肺门、纵隔淋巴结转移,明确中央型肺癌或肺门。To study the methods and value of low field MRI diagnosis of lungcarcinoma. Methods: 65 cases of lung carcinoma with clinical or pathologic identification were studied by low field (0. 16T) MRI, of which 15 cases were also studied by cardiac getting on T1 WI. Results: Low field MRI could better present some kinds of lung carcinoma which positions were special, such as apex pulmonis, lung brink, near diaphragm: could diagnosis lung carcinoma penetrated mediastinum, pericardium, vessels: could distinguish central type lung carcinoma and its following change, could clearly determine the penetrated rage of Pancost's carcinoma: could clearly present the lymphadenectasis of mediastinum or hilum pulmonis and pleura penetration. Conclusion: Low field MRI was also suit for investigation if lung carcinoma had milum or mediastinum lymph metastasis, and for determination the relationship between central lung carcinoma or hilum, mediastinum lymph metastasis and hilum, mesiastinum big vessels.
