Ressonância magnética de pulmão: um novo passo no estudo das doenças pulmonares

Abstract

Magnetic resonance imaging (MRI) of the lung has progressed tremendously in recent years. Because of improvements in speed and image quality, MRI is now ready for routine clinical use. The main advantage of MRI of the lung is its unique combination of structural and functional assessment in a single imaging session. We review the three major clinical indications for MRI of the lung: staging of lung tumors; evaluation of pulmonary vascular disease; and investigation of pulmonary abnormalities in patients who should not be exposed to radiation.Keywords: Magnetic resonance imaging; Lung; Lung diseases; Carcinoma, non-small-cell lung; Lung diseases, interstitial; Pneumonia. ResumoA ressonância magnética (RM) de pulmão progrediu tremendamente nos últimos anos. Devido a melhorias na velocidade e na qualidade de imagens, a RM de pulmão hoje está pronta para a utilização clínica de rotina. A principal vantagem da RM de pulmão é a sua combinação exclusiva de avaliação estrutural e funcional em uma única sessão de imagens. Revisamos aqui as três principais indicações clínicas da RM de pulmão: o estadiamento de tumores pulmonares, a avaliação de doença vascular pulmonar e a investigação de anormalidades pulmonares em pacientes que não podem ser expostos à radiação.Descritores: Imagem por ressonância magnética; Pulmão; Pneumopatias; Carcinoma pulmonar de células não pequenas; Doenças pulmonares intersticiais; Pneumonia.

Endometriose pleural: achados na ressonância magnética

“…Because of improvements in speed and image quality, MRI is now ready for routine clinical use. (7)(8)(9) In both of the cases presented here, chest MRI revealed hydropneumothorax and well-defined, rounded nodules on the pleural surface in the right hemithorax. In Case 1, the pleural effusion had intermediate signal intensity on T1-weighted images, suggesting high protein content, probably related to hemorrhagic products.…”

Magnetic resonance imaging of the chest in the evaluation of cancer patients: state of the art

“…Such a gain in quality represented a progress in the diagnostic performance of the method, allowing for a more appropriate evaluation of chest lesions as compared with the performance observed in the past ( 8 , 9 ) . The evaluation of the traditional morphological parameters such as size, shape, contours and relationship with adjacent structures, has significantly evolved, improving the therapeutic planning ( 6 ) . The introduction of dynamic parameters such as cine-MRI has added new information regarding infiltration of chest wall, mediastinal and vascular structures, strengthening the resectability criteria during the therapeutic planning ( 26 ) .…”

“…However, patients with focal disease should be submitted to treatments that offer real possibilities of healing ( 4 , 5 ) . Therefore, it is important the imaging diagnosis tools provide accurate information about the location, number of lesions, tumor extent, disease activity and biomarkers ( 6 ) . Currently, the set of such information is imprescindible for the most appropriate management of cancer patients, including those with malignant chest tumors ( 6 , 7 ) .…”

Pulmonary capillary hemangiomatosis: an uncommon cause of pulmonary hypertension

“…( 3 - 5 ) We would like to report another uncommon cause of PH, pulmonary capillary hemangiomatosis (PCH), and describe the important role of imaging methods in establishing the diagnostic suspicion of this condition.…”

“…Other complaints are chest pain, chronic cough, peripheral edema, cyanosis, and syncope. ( 3 ) Hemoptysis can be a very useful sign in order to differentiate PCH from pulmonary veno-occlusive disease (PVOD), because it is not found in PVOD.…”
