Bottom Line: It is a quite useful tool in the diagnosis, staging, surgical planning, treatment response evaluation and follow-up of these 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.Abstract available from the publisher.

ABSTRACT
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.

Female, 64-year-old patient with diagnosis of pulmonary adenocarcinoma in theright upper lobe. Intense radiopharmaceutical FDG uptake (hypersignal) is observedin the right lung lesion and contralateral para-aortic lymph nodes, the latterwith standard uptake value (SUV) of 5.1, corresponding to clinical stage N3.

Intense radiopharmaceutical FDG uptake (hypersignal) is observedin the right lung lesion and contralateral para-aortic lymph nodes, the latterwith standard uptake value (SUV) of 5.1, corresponding to clinical stage N3.

Mentions: Functional imaging methods usually detect disease activity before the onset ofmorphological manifestations(15). Withthe development and dissemination of PET/CT, the functional tools gained more prominenceover the last years(16). This methodallowed for the recognition of regions avid for glucose and its molecular analogues suchas fluorodeoxyglucose (18FDG) (Figure1)(17). Such regions maycorrespond to sites of tumor involvement and their evaluation as a whole by conventionalmorphological imaging methods such as CT and MRI provides greater anatomical detail,improving the quality of the information and the management of the patients(18-20).
