Diffusion tensor cardiovascular magnetic resonance can provide insight into the function and microstructure of the scar and adjacent region in myocardial infarction (MI). Imaging the thinned infarcted myocardial wall requires a high-resolution acquisition while frequent arrhythmia, shortness of breath and fatigue make the cohort especially challenging for imaging. A high-resolution STEAM acquisition with an interleaved variable density spiral readout and an off-resonance and T2* correction was previously demonstrated in a healthy cohort. Here, this sequence was successfully applied in 7 MI patients at a spatial resolution of 1.8x1.8x8mm³ and compared to a standard resolution EPI sequence.
