Concordance Between Aspiration Detected on Upper Gastrointestinal Series and Videofluoroscopic Swallow Study in Bottle-Fed Children.

The increasing incidence of pediatric dysphagia has raised questions about how to identify children at risk for aspiration. Multiple investigative imaging modalities are considered in diagnostic algorithms, since dysphagia may involve any or all phases of swallowing. Although upper gastrointestinal (UGI) series and videofluoroscopic swallow study (VFSS) are common procedures, the utility of UGI for detection of aspiration and the impact of oropharyngeal imaging during UGI on radiation exposure have not been well described.
