Establishing a Functional Diagnostic Algorithm

Importance: Pediatric imaging carries the risk of radiation exposure. Children frequently undergo computed tomography with angiography (CTA) for findingsonbronchoscopywithlimitedknowledgeregarding the necessity of such imaging. Objective: To report our experience with all pediatric patients at our institution over an 8-year period with airway symptoms warranting bronchoscopy followed by CTA for potential vascular anomaly. Goals were to report the percentage of positive findings seen on CTA leading to surgery; discuss relative radiation exposure risk and sedation risk for additional radiologic studies; and propose a functional diagnostic algorithm.
