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.
