The clinical use of lung MRI in cystic fibrosis: what, now, how?

abstract：:Patients with HES and pulmonary infiltrates may pose certain diagnostic problems as the infiltrates may be attributed to infection, infarction, congestive heart failure, or HES itself. We report an 87-year-old woman with idiopathic HES presenting with bibasal alveolar infiltrates. Differential cell count in BAL fluid ...
