Fig. 3From: In vitro optimization and comparison of CT angiography versus radial cardiovascular magnetic resonance for the quantification of cross-sectional areas and coronary endothelial functionLinear regression analyses between cross-sectional area (CSA) measurements from computed tomography angiography (CTA) images and known drilled CSAs. For readability, only the regressions corresponding to the same subset of CTA data acquisition and image reconstruction parameters as in Fig. 2 are shown.
