DOI: 10.1002/jmri.29383
Abstract: Cardiac diffusion‐weighted imaging (DWI) using second‐order motion‐compensated spin echo (M2C) can provide noninvasive in‐vivo microstructural assessment, but limited by relatively low signal‐to‐noise ratio (SNR). Echo‐planar imaging (EPI) with compressed sensitivity encoding (EPICS) could address these… read more here.
