Keywords: Heart, Diffusion/other diffusion imaging techniquesCardiac diffusion weighted imaging (DWI) is a novel tool that could provide non-invasive in-vivo microstructural assessment. However, cardiac DWI remains a challenging task due to low signal-to-noise-ratio (SNR) and motion artifacts. The second-order motion compensated (M2C) could be used to decrease the motion artifacts, and Compressed SENSE could improve the SNR of the echo planar imaging (EPI) based sequences. Hence, the combination of M2C DWI and Compressed SENSE was firstly proposed in the present study. We found that M2C DWI using Compressed SENSE showed better overall image quality and higher SNR.
