Recent work in assessing patients with idiopathic pulmonary fibrosis suggests that vascular changes, as assessed by dynamic contrast enhanced lung MRI, are a useful marker to assess disease progression. Therefore this work aimed to develop an image processing pipeline to assess same-day intra-participant reproducibility of quantitative perfusion metrics in a cohort of patients with idiopathic pulmonary fibrosis. From the data here it suggests that these quantitative metrics are not reproducible, even when patients are scanned on the same day.
