Role of New Imaging Capabilities with MRI and CT in the Evaluation of Bronchiectasis

AbstractPurpose of ReviewBronchiectasis is the permanent abnormal dilation of the airways and can be associated with various pathogeneses and outcomes. Proper diagnosis and evaluation of bronchiectasis employs x-ray CT, though emerging research has also shown MRI to be sensitive to the disease. The goal of this article is to review recent research in CT and MRI of bronchiectasis and associated diseases.Recent FindingsTechniques in quantitative CT continue to improve and may improve consistency in bronchiectasis evaluation and reduce reader scoring load. While CT is the “gold standard” for evaluation of bronchiectasis, new techniques in magnetic resonance imaging have dramatically increased in sensitivity to bronchiectasis though without patient exposure to ionizing radiation. MRI may therefore be an attractive alternative to CT in some cases, yet further clini cal trials are necessary.SummaryAlthough bronchiectasis is an irreversible disease, new understanding of airway structure-function relationships may improve clinical management.
