Although R2* relaxation is a complicated process, our results suggest a nearly linear field dependence of cardiac R2*. Admittedly, at 7T the pronounced propensity to macroscopic susceptibility artefacts is challenging and it seemed to spare only the septal regions. The most severe artifact source was the heart-lung interface.
