摘　　要：目的探讨肺癌的磁共振影像学表现。方法分析42例经病理证实的肺癌MRI资料。42例患者均进行MRI常规轴位T_1WI、T_2WI,冠状位T_2WI、轴位DWI扫描。结果 42例肺癌:中央型14例,周围型26例,纵膈型2例;13例有胸腔积液,8例有肺内转移,8例有肋骨转移;病灶T_1WI 64%呈等信号,T_2WI 97.6%呈高信号,DWI呈高信号。结论MRI可以显示肺癌外部和内部影像特点,在纵膈、胸壁侵犯方面有很好的优势。Objective To explore the performance of lung cancer with magnetic resonance imaging. Methods 42 cases of lung cancer which was confirmed by pathology had been analysed their informations of MRI. MR examinations were done at 3.0T MR. Scan sequences were as followed, T2WI/TSE-BLADE, HASTE（ axial andcoronal） , T1WI/VIBE-DIXON （axial）, DWI/EPI （axial）. Results There were 14 cases of central lung neoplasms, 26 cases of perihheral pulmonary cancer, 2 cases of mediasti- num-typed lung cancer in the 42 cases of lung carcinoma; The thorax effusion was found in 13 cases, the lung metastasis in 8 ca- ses, the bone metastasis in 8 cases; 64% lesions of T1WI were shown equal signal; 97.6% lesions of T2 WI were shown high sig- nal ; lesions of DWI were shown high signal. Conclusion MRI can display the external and internal image characteristics of lung cancer, which shows good advantages in the mediastinum and chest wall invasion.
