Magnetic resonance imaging (MRI) has several advantages in the evaluation of cancer patients with thoracic lesions, including involvement of the chest wall, pleura, lungs, mediastinum, esophagus and heart. It is a quite useful tool in the diagnosis, staging, surgical planning, treatment response evaluation and follow-up of these patients. In the present review, the authors contextualize the relevance of MRI in the evaluation of thoracic lesions in cancer patients. Considering that MRI is a widely available method with high contrast and spatial resolution and without the risks associated with the use of ionizing radiation, its use combined with new techniques such as cine-MRI and functional methods such as perfusion- and diffusion-weighted imaging may be useful as an alternative tool with performance comparable or complementary to conventional radiological methods such as radiography, computed tomography and PET/CT imaging in the evaluation of patients with thoracic neoplasias.
磁共振成像（MRI）在评估患有胸部病变的癌症患者时具有多项优势，这些病变包括胸壁、胸膜、肺、纵隔、食管和心脏受累情况。它在这些患者的诊断、分期、手术规划、治疗反应评估及随访中是一种非常有用的工具。在本综述中，作者阐述了MRI在评估癌症患者胸部病变方面的相关性。鉴于MRI是一种广泛可用的方法，具有高对比度和空间分辨率，且不存在与使用电离辐射相关的风险，其与电影MRI等新技术以及灌注加权成像和扩散加权成像等功能方法相结合，在评估胸部肿瘤患者时，可能作为一种替代工具，其性能与传统放射学方法（如X线摄影、计算机断层扫描和PET/CT成像）相当或互补。
