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、纵隔淋区结转移与肺门和纵隔大血管的关系
Methods and Value of Low Field MRI in Diagnosis of Lung Cancer. Methods: A total of 65 cases of lung cancer were collected from clinical and pathological examination. Low-field (0.16T) MRI examination and T_1WI plus ECG were performed. Results: The non-gated short TE sequences performed better. Low-field MRI of some of the occurrence of J special parts of lung cancer, such as the lung tip, lung margin, near the diaphragm showed good mass, can determine lung invasion of the mediastinum, pericardium, blood vessels; to identify the central lung cancer and its secondary changes; to determine Pancost’s tumor The scope of violations is clear. On the mediastinum, hilar lymph nodes and chest wall invasion showed very satisfied. Conclusions: Low-field MRI is also suitable for understanding whether there is hilar and mediastinal lymph node metastasis in lung cancer, and to clarify the relationship between central lung cancer or hilar and mediastinal lymph node metastasis and hilar and mediastinal vessels
