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.
