Longitudinal Functional Magnetic Resonance Imaging to Assess Lung Disease in Cystic Fibrosis.
RATIONALE Matrix pencil decomposition magnetic resonance imaging (MP-MRI) enables quantitative assessment of lung ventilation and perfusion and was shown to correlate with contrast-enhanced (CE) perfusion MRI. OBJECTIVES To determine the longitudinal course of MP-MRI parameters in people with cystic fibrosis (pwCF)....
