Serial Decline in CT Markers of Lung Volume Demonstrates IPF Progression
An observational study published in the journal European Radiology found that serial decline in computed tomography (CT) markers of lung volume—specifically, annualized 25% reduction in aortosternal distance (ASD)—provides evidence of disease progression in patients with idiopathic pulmonary fibrosis (IPF). This evidence, the study notes, is not always identified by forced vital capacity (FVC) trends or…
