In this presentation, researchers will describe how using an antiscatter grid in adult bedside chest exams significantly improved perceived image quality for both mobile digital radiography (DR) and computed radiography (CR).

More than 100 intensive care patients were included in this German study. Patients received bedside chest radiographs using four acquisition techniques: CR and DR with and without a grid. Image quality was then evaluated by four radiologists using a nine-point visibility scale. They evaluated lung parenchyma, soft tissues, thoracic spine, foreign bodies, and overall image quality.

Image quality of the DR images with a grid was significantly higher than quality without a grid for all structures, the researchers found. The use of a grid in CR significantly improved overall image quality and lung parenchyma and soft-tissue delineation, but foreign body delineation was better without a grid.

The visibility scores for DR images were significantly higher than the CR scores for all structures.

"We are very interested in improving the diagnostics in intensive care medicine, [and] we have now improved the technological basis especially for the flat-panel technology," Dr. Thomas Vogl, PhD, from the University of Frankfurt, told AuntMinnie.com.

The system also already has high clinical acceptance, he added.
