The bar chart shows the percentage of paired image assessments that were rated as “85 protocol better,” or “125 protocol better” by human graders, for the respective categories of image quality, noise artefact and vessel projection artifacts. All three qualitative parameters were statistically significant, with higher odds of graders preferring the 125 kHz protocol.
