Central airway abnormalities in neonates, e.g. dynamic collapse and stenosis, are serious complications often associated with preterm birth and congenital abnormalities, but have not been extensively studied. These conditions are most often assessed through clinical bronchoscopy, which can be unreliable and poses increased risks to patients. Here, we demonstrate novel visualization of static and dynamic neonatal airway abnormalities on virtual bronchoscopy from high-resolution, retrospectively respiratory-gated ultrashort echo-time MRI, which exhibits good agreement with clinical bronchoscopy. This virtual technique allows for assessment of neonatal airway abnormalities that is readily interpretable to clinicians familiar with clinical bronchoscopy.
