A navigated, simultaneous slice excitation
implementation for accelerated free-breathing cardiac
diffusion imaging using STEAM is proposed. By using an
improved navigator gating strategy and dual-slice
excitation, significant gains in scan efficiency are
demonstrated. Diffusion tensor maps acquired using the
proposed method compare favourably with data from
conventional sequential slice breathhold acquisitions.
