DAH is radiologically characterised by a nonspecific alveolar-filling pattern. Diagnosis or suspicion of DAH needs to be supported by the evidence of haemoptysis and/or rapid-onset anaemia. CT is superior in detecting ground-glass opacities and is required in cases of suspected DAH with normal CXR findings.
Our results demonstrate the limited usefulness of chest radiography in the diagnosis of ABPA in patients with cystic fibrosis. The most significant abnormalities are nonspecific and commonly seen on baseline films in cystic fibrosis without ABPA and persist after treatment in most cases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
