In cardiac diffusion imaging, spin echo (SE) and stimulated echo (STE) diffusion sequences measure diffusion at very different diffusion time. It has been reported that the resulted diffusion parameters are different. In this work, we investigate how the difference in derived diffusion parameters from SE and STE experiments, if exists, affects the estimation of myocardial fiber organization through the assessment of the cone of uncertainty (COU) of the major eigenvector of the diffusion tensor.
