Diffusion magnetic resonance imaging (dMRI) is an advanced
clinical imaging technique based upon characterizing the water
flow within body tissues. Although models of higher order (HO)
than diffusion tensor imaging (DTI) have been successfully ap-
plied to brain dMRI, the peculiarities of the heart hinder its appli-
cation on this muscle. However, these models have been proven
as a powerful way to get insights in the microstructure of organs.
In this work we have applied both DTI and a HO model to two
ex-vivo pig heart acquisitions for measuring their differences in a
metric that we call “Non-Gaussianity” and then check how these
differences are gathered on infarcted tissue. Further researching
may be needed to both confirm this correlation and make these
models feasible to clinical practice.The authors acknowledge grants PID2020-115339RB-I00,
