3D MRI of the myocardium after an ischemic attack could provide an accurate scar segmentation, much needed by the clinicians. However, this type of acquisition, usually obtained by late gadolinium enhancement (LGE), is very time consuming. We combined a wave acquisition with an inversion pulse and a variable density Poisson undersampling strategy to accelerate 3D cardiac imaging. Retrospectively subsampled images of a sheep heart were successfully reconstructed with an acceleration factor of 4, opening the path to a fast high-resolution 3D LGE acquisition.
