Spin echo based cardiac diffusion tensor imaging is
highly sensitive to cardiac motion. Second order motion
compensated diffusion encoding gradients are implemented
to reduce sensitivity to cardiac motion. In this study
the helix elevation angle in-vivo is compared to the
post mortem condition in the same pig. Good correlation
between in-vivo and post-mortem imaging was found
indicating, that bulk motion is sufficiently suppressed
by second order motion compensated diffusion encoding.
