Cardiac diffusion-weighted imaging (CDWI) is an emerging method for non-invasive assessment of cardiac microstructure. In CDWI, averaging and triggering are routinely used to mitigate motion artefacts, which results in long acquisition times. We have developed a novel motion-compensated spherical tensor encoding technique that reduces the acquisition time by a factor of up to three. Quantitatively, the method yields similar mean diffusivity as conventional methods, but enables accurate measurements in less than a minute.
