The purpose of this study is to determine if measurements of active collagen deposition using \[68Ga\]CBP8 positron emission tomography (PET) and tissue injury using dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) can predict an individual patient's pace of disease progression in non-idiopathic pulmonary fibrosis interstitial lung disease (non-IPF ILD) and identify which individuals will develop progressive pulmonary fibrosis.
