Dynamic Airway CT is Diagnostic for Tracheomalacia in Children

Dynamic Airway CT is Diagnostic for Tracheomalacia in Children

The purpose of this pilot interventional study is to evaluate the use of Dynamic Airway Computed Tomography (DA-CT) for diagnosis of tracheomalacia in children 0-18 years for whom flexible bronchoscopy has been performed. The primary aims are to evaluate the diagnostic accuracy, image quality, and radiation exposure of DA-CT as a potential noninvasive alternative to the gold standard of flexible bronchoscopy in the diagnosis of tracheomalacia. The results from this pilot study will help to estimate sample size for a larger-scale study with more precise estimates of DA-CT diagnostic potential.

Inclusion Criteria:

• Participants 0-18 years old, with
• Clinically indicated flexible bronchoscopy has been performed

Exclusion Criteria:

• Pregnancy or breastfeeding
• Unable to undergo CT scanning without sedation
• Patients with tracheostomy
