Fig. 1. —Graph shows mean difference scores between scanning techniques for observer confidence, image graininess, and artifacts at each anatomic location (reformatted helical CT scores versus conventional CT scores). Whiskers represent standard error of mean values. Note that confidence and graininess bars project in opposite direction from artifact bars, indicating that reformatted helical CT was associated with higher confidence and more graininess but fewer artifacts than conventional CT.
