Spin-echo based diffusion weighted sequences allow for
single-shot acquisitions but are highly sensitive to
cardiac motion. In this work second order motion
compensated diffusion encoding was implemented and
compared to first order motion compensation during
systolic contraction of the heart. Second order motion
compensation was found to yield an extended systolic
window suitable for imaging when compared to first order
motion compensation (210 vs. 90 ms) thereby enabling
spin-echo DTI at various points during the cardiac
cycle.
