Fig. 7From: In vitro optimization and comparison of CT angiography versus radial cardiovascular magnetic resonance for the quantification of cross-sectional areas and coronary endothelial functionLimit of detection (LOD) or smallest detectable cross-sectional area (CSA) difference obtained using the optimized computed tomography angiography (CTA) protocol for the different voxel sizes investigated in our study. Line plots show the mean and standard deviation. For the reader’s convenience, the LOD axis (vertical axis) is provided in absolute CSA differences (in mm2) and difference relative to a 3-mm nominal diameter (in %) in parenthesisBack to article page
