Fig. 1. —Graph shows results of Brunner and Langer's test
[14] comparing accuracy of
standard digital chest radiography (CXR) alone and in combination with
dual-energy (CXR + DE) review. Values between 0 and 1 are calculated for each
individual reviewer (A–D). Improvement contributed by adding DE images
was significant (p < 0.01). Slope of line connecting reviewers'
scores inclines upwards, reflecting increase in accuracy of detection.
