The researchers had decided to study the quality review process at their institution after noticing a number of radiographs that were too light and had too much mottle. However, after reviewing the images with the lead technologist on the technologist workstation, they found that the radiographs looked fine on the lower-resolution color monitor.
"We realized that there was a process issue that would perpetuate underexposed images, and that the technologists would not be able to improve with the current workstations," Brandser said.
They then elected to formally study the difference between grayscale and color monitors to see if there was a difference in quality assurance assessment, he said.
"We found a statistically significant difference, supporting our initial observation," Brandser noted.
