Computed radiography (CR) has various advantages such as dynamic range. Diagnostic accuracy with CR using reduced radiation dose is considered comparable with that of conventional film-screen radiography in diagnosing apparent chest abnormalities. In addition to reducing the radiation dose, delineation of the various structures in infants can be obtained with CR using postprocessing. Even in cases involving inadequate exposure, appropriate information can be obtained by postprocessing. For these reasons, the cumulative dose of radiation exposure will be reduced. Thus, reduction of the radiation dose is the greatest advantage of using CR in pediatrics.
