The accelerated motion compensation (aMC) using higher order motion compensated gradients with asymmetric bipolar diffusion waveform can improve the image quality of cardiac DTI compared with conventional method and provide the relatively constant DTI marker. In LVH patients, aMC-DTI derived possible preliminary insights into detection of abnormal changes in myocardial microstructures in-vivo, even in segments without LGE.
