Xenon MRI and Progressive ILD

The XENON ILD study is a single arm, un-blinded study at Duke University enrolling patients with non-idiopathic pulmonary fibrosis (IPF) progressive fibrosis (PF) interstitial lung disease (ILD). Patients who meet criteria for ILD-progression (defined below in inclusion/exclusion criteria) will be consented prior to the initiation of anti-fibrotic therapy. Subjects will undergo an approximately hour long comprehensive MRI protocol, including administration of multiple doses of hyperpolarized 129Xe. The subjects will have this initial study prior to initiation of anti-fibrotic therapies and repeat MRI studies at 3, 6 and 12 months following the initiation of therapy. If subjects do not decide to initiate anti-fibrotic therapy per discussion with their physician, then the 3, 6 and 12 months repeat studies will initiate based on time after enrollment.
