Figure 2.

a-c. Ranking of acquisition and reconstruction parameters. The image in (a) represents the best overall z-scores (lumen and stent z-score). The image in (b) shows the best z-score for the depiction of the stent (sharpness and stent width z-score) and the best z-score for the visualization of the lumen (lumen width, CNR, and pseudoenhancement). The image in (c) shows the best z-scores for the categories: sharpness, lumen width, stent width, CNR, and pseudoenhancement. Z-scores were obtained statistically by standardization. In square brackets listed are [the mode of acquisition; the monoenergetic photon energy setting in case of DE; the tube voltage; the reconstruction kernel]. CNR, contrast-to-noise ratio; DE, dual-energy; SE, single-energy; Sn, tin-filtered.
