Increased regional ventilation as early imaging marker for future disease progression of interstitial lung disease: a feasibility study

This is the authors' abstract. We don't add key points for this paper.

• Voxelwise correlation of serial CT scans suggests spatial correspondence between increased ventilation at baseline and structural changes at follow-up. • Regional assessment of pathologically increased ventilation at baseline has the potential to prospectively identify tissue at risk for developing fibrosis. • Presence and extent of pathologically increased ventilation may serve as an early imaging marker of disease activity.
