From: Diffusion MRI tractography of the human heart In Vivo at end-diastole and end-systole
Bar plots of MD, FA and diffusion tensor eigenvalues computed across all 12 sectors within the LV of 3 normal human hearts. As the myocardium contracts (from end-diastole to end-systole), extracellular volume decreases and the myocytes thicken, resulting in concomitantly reduced MD and FA. The reduction in diffusivity and anisotropy is confirmed by a proportional decrease in all three eigenvalues.
