Stimulated echo acquisition mode (STEAM)  imaging has been used to probe myocardial microstructure in-vivo. However STEAM imaging requires 2 R-R intervals, sophisticated respiratory navigator gating  and is subject to myocardial strain [3, 4]. Spin-echo (SE) based single-shot diffusion weighted sequences present an appealing alternative [5, 6]. In this work the sensitivity to bulk motion of cardiac SE diffusion tensor imaging is addressed by using second order motion compensated (MC) diffusion encoding.
Second order motion compensated cardiac SE diffusion encoding significantly decreases the sensitivity to bulk motion compared to first order motion compensated diffusion gradients across the heart.
