We evaluated the feasibility of the combined use of MoSE CINE imaging (to determine exact TD as a preparation procedure), MoCo-TSE-DWI acquisition and FEIR post-processing (to register the respective diffusion images) for improving the robustness of quantitative cardiac IVIM mapping. Combined use of the MoSe-CINE procedure for determining the exact cardiac trigger delay, MoCo-TSE-DWI acquisition, and FEIR post-processing to register among all source images, could be useful to increase the robustness of image quality and improve the quantitative accuracy in myocardial IVIM mapping.
