Fig. 3

Absolute and quantitative iodine-based analysis of myocardial dynamics derived from 1-compartment fitting of iodine density-to-time attenuation curves in the active myocardium-like tissue area. The phantom’s spongy myocardium-like tissue in axial view is imaged. a Iodine density image at 12 s of the perfusion protocol in greyscale to distinguish it from perfusion maps. b Image with blood flow normalised to the tissue volume (mL/min/100 mL). c Image showing the volume fraction representing the compartment volume relative to the total volume of the region of interest (e.g., mL/100 mL). d Mean transit time map. Image parts, which appear bright red in d are classified as haemodynamically affected myocardium-like tissue (blue arrow)
