Reducing the Radiation Dose During Excretory Urography: Flat-Panel Silicon X-Ray Detector Versus Computed Radiography

Abstract

With half the exposure dose of computed radiography, the flat-panel X-ray detector produced urograms with an image quality equivalent to or better than computed radiography.

Prospective study of digital radiographs versus conventional screen films in Small Bowel Follow-Through examination

“…There are some studies that indicate that the same principles of better image quality and possible radiation dose reduction are applicable in abdominal radiographs as well [9,10]. Nevertheless, we are not aware of any studies that prospectively compared DR and conventional SF radiography of the abdomen after ingestion of contrast material, as was done in this work.…”

“…There are numerous studies that evaluate and demonstrate improved image quality concurrent with reduced radiation doses for chest [1,[5][6][7] and skeletal radiography [3,8] yet only a small number of studies have addressed this issue for abdominal radiography [9,10], and none of them compare the digital radiographs to the conventional ones following ingestion of contrast material.…”

Reducing dose in urography while maintaining image quality—a comparison of storage phosphor plates and a flat-panel detector

“…A presentation of images on hard copies could probably solve this problem. However, an evaluation of images presented on hard copies as Zähringer et al [7] did in a recently published study does not exploit the full benefit of the digital technique since the ability to view and adjust image settings directly on a monitor is one of its major advantages. The image viewing tools on a workstation, such as window and level settings and zoom functions, may give even better representation of lowcontrast objects such as kidney and psoas outlines.…”
