In-vivo cardiac diffusion using either the Intra-Voxel
Incoherent Motion (IVIM) model or the Diffusion Tensor
Imaging (DTI) model shows promise to provide new
insights into heart pathologies. However, due to the
combined challenge of respiratory and heart motion,
currently proposed acquisition methods are quite
demanding for unhealthy patients. In this study, we
propose to use the motion information provided by a
navigator to prospectively update in real time the
position of the diffusion-weighted slices in order to
offer an efficient free-breathing strategy for rapid and
improved cardiac diffusion acquisition using a
single-shot Spin-Echo EPI sequence (SE-EPI).
