Abstract
BACKGROUND:
Many image-intensifier fluoroscopy systems have been replaced by flat-panel detectors in recent years.
OBJECTIVE:
To compare the level of contrast, image resolution and radiation dose between an image-intensifier and a newer-generation flat-panel detector system in a pediatric radiology unit.
MATERIALS AND METHODS:
We compared two systems - a conventional image intensifier and a newer-generation flat-panel system. We measured image quality and radiation dose using a technical phantom. Additionally, we retrospectively compared age-matched fluoroscopic pediatric voiding cystourethrography (n = 15) and upper gastrointestinal investigations (n = 25).
RESULTS:
In phantom studies image contrast was equal while image resolution was higher and mean radiation dose lower using the flat-panel system (P
