Figure 1From: Reducing variability in dual bolus cardiac MRI by using empirical contrast ratiosa) The unsaturated portion of the full bolus AIF in a dual bolus experiment is used to empirically determine a contrast concentration ratio that best matches the dilute ("mini") bolus to the full bolus. b,c) Using the emprically derived ratios improves MRI perfusion measurements against gold standard microsphere data EditBack to article page
