Desempenho da ressonância magnética para avaliação das alterações pulmonares em crianças com fibrose cística

Abstract

Introduction : Cystic fibrosis is a chronic disease that requires regular monitoring and testing. Chest CT is the gold standard to the evaluation of the pulmonary parenchyma, but because of the risk caused by radiation, technical alternatives should be evaluated. MRI is a test that does not use radiation. The aim of this study is to evaluate the performance of MRI chest and correlated with clinical parameters such as spirometry, Shawchman clinical score and the 6-minute walk test. Methods : 19 patients with cystic fibrosis Clinic underwent magnetic resonance of the chest, 6-minute walk test, FEV1 and clinical Shwachman score. MR score was evaluated and correlated with other parameters. Results : MRI correlated with the 6-minute walk test and the clinical score of Shwachman, but not with FEV1. Conclusion : MRI is a good alternative for airway and lung parenchyma assessment in patients with CF, showing a significant correlation with the6-minute walk test and the clinical score of Shwachman.
