Excerpt

The ability to interrogate cardiac microstructure has led to much recent interest in in-vivo cardiac diffusion tensor imaging (cDTI). However, when compared to studies performed in neuro-imaging, very little work has been done to determine the optimal diffusion encoding schemes. Previous work has suggested that accuracy is improved by increasing the number of diffusion encoding directions(N_dirs)^1,2, but comparisons in the heart have been limited to fixed animal specimens³. Here we compare parameters derived from cDTI using data acquired in vivo with an increasing N_dirs. …
