Abstract:Free-breathing lung MRI has been shown to be a responsive measure to CF pulmonary exacerbations treatments but have not been used to track stable disease progression longitudinally. In this study we determined the intra- and inter-scan reproducibility of free-breathing lung MRI in healthy and stable pediatric CF across 2 visits and compared to hyperpolarized Xenon MRI (Xe-MRI). Xe-MRI and free-breathing lung show a high intra-scan reproducibility in stable CF subjects, but free-breathing lung MRI showed a low … Show more
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.
